“Integral Relativity, as an extension of General Relativity, has three proposed Tenets: (a) The Equation of Energy with Consciousness; (b) The Law of Conservation of Consciousness; (c) The Integral Relativity of Energy, Consciousness and Mind via the Kosmic Constant.

It is corroborated by E. Rauscher’s Complex Eight Dimensional Model of Minkowsky Space; Haramein’s Holographic Resonance; the instantaneous conveyance of information in Locality by the Non-local wave function, by Pusey, Barrett and Rudolph; the work of Penrose and Hameroff in Quantum Consciousness, and that of Dean Radin at IONS; and the Afterlife Experiments of Gary Schwartz.

Introduced was an extension of Wilber’s Integral All Quadrants, All Levels (AQAL) model called the AQAL Cube, which correlates non-physical existence with physical existence in order to map the Integral Relativity of Energy, Consciousness and Mind; and which also differentiates Consciousness as a non-local AQAL Domain.

Also proposed was an experiential code for the conveyance of information between Consciousness and Quantum Mind in compliance with Hameroff’s gamma synchrony.

The differentiation between Consciousness and Mind is made by the AQAL Cube’s Third Axis Injunction, introducing the radical notion that Consciousness is non-local or Subtle awareness, and Mind is its correlated local or Concrete means of inaction.

And Proposed that just as this Concrete physical Domain is full-spectrum, so is the correlated Subtle Domain, where the two spectrums function and correlate as parallel universes embedded in and embodied by each other, in compliance with modern science.

All the scientific evidence brought to bear corroborates this hypothesis of a Heaven-Earth polarity, as well as corroborating the tenets of Critical Realism, in expanding and explaining its paradigm of the Domain of the Real and the Domain of the Actual – the Subtle mechanisms (former) that underlie Concrete manifestation (latter) – to enable the mapping of those polarities as an integral whole.

Proposed that the terms Consciousness and Mind be no longer used synonymously in the scientific community, but differentiated as an integral Energy continuum.

Integral Relativity predicts that the observer and observed are a mutually inclusive Consciousness/Mind/Energy continuum, which expands as an evolving holarchy of knower and known all the way to a Supreme Knower of a Supreme Knowledge.

“The ‘Quantum Soul’ hypothesis (Hameroff and Chopra, 2009) has produced a new wave of thinking as NDE/OBEs indicate the existence of soul which is so far being stapled as religious tradition and shunned by conventional science.

However, the time is right to reinvestigate and formulate this hypothesis up to a law, which is distinctively verifiable. Penrose-Hameroff ‘ORCH-OR’ model is also a quantum approach dealing of consciousness (microtubule quantum computations inside the neuron) to fluctuation in fundamental space time geometry, the fine-scale structure of the universe.

NDE/OBEs could conceivably exist independent of biology in various scalar plans in space time geometry. Not only in eastern religion but also in western religion for thousands of years theory like reincarnation, tele-transportation and re-birth have been recorded at many times.

The near death experience and embodiment of spirit (Van lommel et al 2001, Parnia et al 2007) have been recorded most typically in patients who have been resuscitated after cardiac arrest, similarly (Prakash 2010) has depicted the presence of soul in all her attire (what she has on her body at the time of unnatural death) in a depiction of disembodiment case study.

The patients describe similar experiences of vision of white light, passing through a tunnel, serenity, conversing with deceased one, loved one and out of the body experiences. Also, the death or fear of death vanishes (Chopra, 20060, (Greyson, 1993). Modern science is unable to explore and actually ignoring and denying such experiences (Blanke et al 2004) as unscientific folly, illusion etc.

Therefore, still we are unable to produce a theory of consciousness. The hard produce theory of consciousness. The hard problem (Chalmers 1996) is a real question: how cognitive process we accompanied is driven by phenomenal conscious experience?

There is still no accounting for conscious experiences, the self, free will or ‘qualia’- the essence of experienced perception. The theory of enlightment is nowhere to actually delineate the process involved.

The first person experiences: Many of the western workers consider that consciousness occurs is merely a an illusion or the ride (Dennett 1991, Wegner 2002), which Huxley (1893) said ‘helpless spectators’. Also, unconventional theory of ‘Gap Junction’ is that when various neurons open and close, enabling mobile zone of gamma synchrony to move about the brain, mediating consciousness (Hameroff 2006, 2010).

That is also not sufficient to explain consciousness mechanism in brain. The approaches of chemical reaction, electric signals and biological functions of neuroscience are unable to explain it alone therefore seeking convincing answers at the quantum level.

Since the quanta of soul is a quantum reality, as part of whole system. The summation of every part cannot have greater value than the whole system as the system scientist have realized also (Prakash 2011). A theory new shall be proposed that how soul and its experience, universe and its evolution is of quantum in nature with the help of electro magnetic bio field theory (Richa and Prakash 2011,12,1314,15).

If the path that photons take through a double-slit interferometer is known by any means, then the photons will behave like particles, otherwise they will behave like waves. Numerous interpretations of this observational effect, associated with the “quantum measurement problem,” have been proposed.

Overall the evidence strongly supported the hypothesis, but with a surprise. It was not the case that observation always “collapsed” the wave function, as the authors originally expected. But rather that the interference pattern became sharper or more diffuse depending on the observers’ intentions, where intention was operationally defined by the nature of the feedback used to link the observers to the optical system.

This outcome is consistent with consciousness as an active “steering force” rather than as a passive factor. It is also consistent with a half-century of prior empirical research using other targets of mental intention. These studies therefore suggest, in accordance with interpretations of quantum mechanics discussed by von Neumann along with Bohr, Schrodinger, Eddington, Jordan, Pauli, Planck, Jeans, Godel, London, Bohm, Wheeler, Squires, and more recently Stapp, that the observer is an inextricable part of the measurement process.

Discussions about the quantum measurement problem have tended to focus on philosophical and theoretical arguments. This has led to over a dozen different interpretations and strongly held opinions on all sides. Our experiments are important because they offer a means of empirically informing, and possibly resolving, this long-standing debate.

“The nature of consciousness is a mysterious concept with many medical and spiritual implications. Investigation of consciousness can be performed by making an interference between this criterion and any level of living matter. A recently presented method of action on consciousness is Faradarmani that introduced by Mohammad Ali Taheri since 2005. Faradarmani, by definition, is connection between universal consciousness and elemental consciousness.

In other word, Faradarmani is the interference in the conduction of consciousness at the non vital and vital levels (organism, cell and molecule). In this method, the main concept is to make a special connection between the consciousness of subsystem (object of study) and the source of consciousness of the ecosystem (the universal consciousness).

The mechanism of this connection at the typical experiment is a mental interaction between three elements: universal observer (researcher), intermediate observer, and the universal consciousness.

After observation of many medical advantages of the Faradarmani method in the treatment of various physical and mental disorders in our country and some other countries, we had decided to investigate this interference at the lower levels of complexity of biological systems.

Therefore, our candidates for examination of this interference was on the two levels: the cellular level, Hela cell lines, and the molecular level, microtubule protein polymers, consisting of alpha and beta tubulins, known as the consciousness linked proteins of biological system.

Our experiments on the Hela cell line by cell survival and cell cytometry analysis show a significant decrease in the cell growth efficiency (~30%) without any changes in the cell viability; moreover, the effect of Faradarmani on the tubulin polymerization was investigated spectrophotometrically and a remarkable increasing in the polymerization rate was observed.

The results indicate the effect of Faradarmani on the cellular and molecular levels which could provide evidence for the observed cases of treatment of various disorders.

“The issue of the connection between the physically described activities of a person’s brain and his or her psychologically described conscious perceptions and intentions is examined within the Freeman-Vitiello quantum framework based on recent neuroscience data.

This framework, in concordance with the ideas of Niels Bohr as refined by the work of John von Neumann, elevates the role of human consciousness from a mechanical by-product of a deterministic classical physically describable process to a psychologically describable input into the physically described aspects of an evolving psycho-physical reality.

The orthodox quantum idea that the aspects of reality described in the terminology of classical mechanics are embedded in a reality that is not describable in classical physics terms is manifested in the fact that the classically describable neuronal structure is embedded in a neuropil substrate that has the dynamical character of a superfluid that makes a second-order phase transition in conjunction with each conscious experience.

This adds detailed mathematical structure to the basic quantum idea that the classically described aspects of reality are embedded in an not-classically-describable reality closely connected to causally efficacious conscious experiences. [P1 300 Quantum Neuroscience and Consciousness Henry P. Stapp (Lawrence Berkeley Laboratory, University of California at Berkeley, Berkeley, CA )

“Hameroff and Penrose theorized that consciousness derives from fine scale activities inside neurons (Hameroff & Penrose, Physics of Life Reviews, 2014).

This theory is now corroborated by a recent discovery of quantum vibrations in microtubules (i.e. a cell’s structural skeleton) through work led by Bandyopadhyay.

One important question to pose is regarding the originating source of these quantum vibrations – where did they originate from? Could all cells in the brain be entangled with one another? If yes, how did it all begin? Before we were adults, we were babies; and before that, we were fetuses in wombs. A human being is first formed when a sperm impregnates an egg, and thereby fertilizing it to life.

Our human brain and body started merely as a single cell, which subsequently divided, multiplied and grew, until an entire brain and body is formed. It is therefore not too far fetched to consider the possibility that every cell in the entire brain is entangled to the quantum vibrations from the original single fertilized egg cell.

If we were to take another step back and ponder about the sperm and the egg, each of these was part of a male and female adult (i.e. the parents of the child), and therefore, entangled with their respective quantum vibrations.

These adults, in turn, have their own parents. Going along this chain of thoughts, it does make one wonder how widespread entanglement could be; from the current human generation to the previous; back up all the ancestral

family trees to the beginning of the Homo sapiens species; stretching wide throughout the entire animal kingdom (via Darwinian evolution theory).

{The ancestral family tree would then include the 1st Homo sapien-saiens’ uterances, grunts, language and singing, Pentatonic Scales.

This opens up the possibility and the plausibility that the entire human population and all biological life forms on this planet at the present time are entangled with each other – perhaps to varying degrees.

So, just how much further back could this entanglement go? It could go as far back as the beginning of time – the Big Bang itself, where everything was a one.

It is as if quantum entanglement is a means of perpetuating the vibrational “essence” of whatever it was that created life more than 13.8 billion years ago.

Everything began from one; everything was entangled; everything is still entangled. We are all connected together, with each other, to the vastness and entirety of the universe, as One Mind (Dossey, 2013).

The current notions of quantum vibrations, entanglement and consciousness are assumed confined just to the brain, a 1.35 kg piece of neurobiological mass.

Here, I propose to broaden these notions beyond consciousness and the brain to the entire body itself, via quantum biology.

After all, microtubules are the skeletal support structures for cells, and cells are the basic building block of the human body.

Furthermore, the human body is associated with notions such as energy fields, chakras and auras.

I will share a few thoughts on consciousness, energy and healing, from the perspective of Core Energetics – a psychotherapy modality that integrates the body, emotions, mind, will and spirit.

Lao Tzu (or ‘Laozi’) was the ancient Chinese founder of Taoism, one of 3 major Chinese philosophies (alongside Buddhism and Confucianism). His many famous quotes include ‘the key to growth is the introduction of higher dimensions of consciousness into our awareness’, and he advocated living in harmony with ‘the Tao’, the ‘path’ or ‘principle’, a set of values intrinsic to nature and reality.

Lao Tzu also formalized the ‘I Ching’, a system of human behaviors and mental states based on hexagrams, sets of 6 binary symbols with 64 possible states. These three aspects of Lao Tzu’s ancient wisdom appear consistent with modern quantum approaches to consciousness.

For example (1)’higher dimensions of consciousness’ may relate to fractal-like patterns at different spatiotemporal scales in the brain, extending from the EEG (~ 0 to 100 hertz, ‘Hz’) at the slow, large-scale end, inward to deeper-level, faster (‘higher’) quantum level dynamics, e.g. in cytoskeletal microtubules inside neurons. (2) The notion of ‘path’ or ‘principle’, a set of values intrinsic to nature and reality, is comparable to ‘Platonic values’ (closely associated) suggested by Roger Penrose to exist in the structure of spacetime geometry, able to influence conscious perceptions and choices. (3) The ‘I Ching’ suggests mental states and behaviors relate in some way to hexagrams of symbols composed of 6 binary ‘bits’, with 64 possible states per hexagram.

Biological memory, language and consciousness may rely on information in hexagonal lattices of microtubule polymers.

Craddock et al (2012) have shown how synaptic information may be encoded in microtubules by CaMKII enzymes, each containing hexagons of 6 bits of information.

Hexagon-based mental processes are also seen in the Nobel prize-winning (Moser et al, 2008) work on ‘grid cells’, showing how spatial location is represented in hexagonal grids with different scales at different layers in the brain’s entorhinal cortex.

In this presentation we compare the 64 states of the I Ching with 64 information states of a microtubule lattice region mediated by CaMKII phosphorylation.

If Lao Tzu and many others were correct, wisdom and knowledge may be gleaned from subtle quantum harmony with the structure of the universe. 1) Hameroff & Penrose Phys Life Revs (2014) 11 (1), 39-79, 2) Sahu et al, 2013a, Biosensors and Bioelectronics 47, 141-148. 3) Sahu et al, 2013b, Applied Physics Letters 102, 123701. 4) Sahu et al, 2014, Scientific Reports 4, 7303. 5) Craddock et al, 2012, PLoS Comput Biol 8(3): e1002421.

Neural oscillation is rhythmic or repetitive neural activity in the central nervous systemNeural tissue can generate oscillatory activity in many ways, driven either by mechanisms within individual neurons or by interactions between neurons.

In individual neurons, oscillations can appear either as oscillations in membrane potential or as rhythmic patterns of action potentials, which then produce oscillatory activation of post-synaptic neurons. At the level of neural ensembles, synchronized activity of large numbers of neurons can give rise to macroscopic oscillations, which can be observed in an electroencephalogram.

Oscillatory activity in groups of neurons generally arises from feedback connections between the neurons that result in the synchronization of their firing patterns. The interaction between neurons can give rise to oscillations at a different frequency than the firing frequency of individual neurons. A well-known example of macroscopic neural oscillations is alpha activity.

Neural oscillations are observed throughout the central nervous system at all levels, and include spike trainslocal field potentials and large scale oscillations which can be measured by electroencephalography (EEG). In general, oscillations can be characterized bytheir frequencyamplitude and phase. These signal properties can be extracted from neural recordings using time frequency analysis.

In large-scale oscillations, amplitude changes are considered to result from changes in synchronization within a neural ensemble, also referred to as local synchronization.

In addition to local synchronization, oscillatory activity of distant neural structures (single neurons or neural ensembles) can synchronize.

Neural oscillations and synchronization have been linked to many cognitive functions such as information transfer, perception, motor control and memory.[2][3][4]

Neural oscillations have been most widely studied in neural activity generated by large groups of neurons. Large-scale activity can be measured by techniques such as EEG.

In general, EEG signals have a broad spectral content similar to pink noise, but also reveal oscillatory activity in specific frequency bands. The first discovered and best-known frequency band is alpha activity (7.5–12.5 Hz)[5] that can be detected from the occipital lobe during relaxed wakefulness and which increases when the eyes are closed.[6]

Other frequency bands are: delta (1–4 Hz), theta (4–8 Hz), beta (13–30 Hz) and gamma (30–70 Hz) frequency band, where faster rhythms such as gamma activity have been linked to cognitive processing. Indeed, EEG signals change dramatically during sleep and show a transition from faster frequencies to increasingly slower frequencies such as alpha waves.

In fact, different sleep stages are commonly characterized by their spectral content.[7] Consequently, neural oscillations have been linked to cognitive states, such as awareness and consciousness.[8][9]

Although neural oscillations in human brain activity are mostly investigated using EEG recordings, they are also observed using more invasive recording techniques such as single-unit recordings.

Neurons can generate rhythmic patterns of action potentials or spikes. Some types of neurons have the tendency to fire at particular frequencies, so-called resonators.[10]

Bursting is another form of rhythmic spiking. Spiking patterns are considered fundamental for information coding in the brain. Oscillatory activity can also be observed in the form of subthreshold membrane potential oscillations (i.e. in the absence of action potentials).[11] If numerous neurons spike in synchrony, they can give rise to oscillations in local field potentials. Quantitative models can estimate the strength of neural oscillations in recorded data.[12]

34 Dark Energy: New Possibilities for The Science of Consciousness Gavin Rowland (School of Medicine, Monash University, Australia, Castlemaine, Victoria Australia) Dark energy appears to occupy all space, and therefore presumably also occupies the subatomic spaces within the atoms of our brains. Yet very little is known about it. Could dark energy be the extra ingredient we require to understand consciousness? In this work, I present a new and detailed theory of the mind, in which nonmaterial consciousness interacts quantum mechanically with the brain. Dark energy offers a number of possible interesting properties. Firstly, being nonmaterial, dark energy is not necessarily bounded by the speed of light. Nonlocal activity escapes the usual restrictions of causality, enabling passage of nonmaterial information backwards in time and instantaneously across distances. This is proposed to introduce new insights to problems such as free will and the binding problem. The ‘otherness’ and intentionality of conscious experiences may not be as hard to explain if they are occurring in a separate, nonmaterial realm. I suggest that existence can be defined as a ‘what’, a ‘when’ and a ‘where’. It is proposed that the ‘what’ of our universe (i.e. complexity – atoms, molecules, life forms) is actually a fundamental dimension comparable to space and time. If it is a dimension then, similar to space, it should be capable of an ongoing expansion in the direction of increasing degrees of complexity. And indeed it is – as Stuart Kauffman puts it, our universe is “indefinitely open ‘upward’ in complexity.”(1) I then suggest that the laws and constants of the universe (seemingly finely tuned for the eventual existence of complex life) are all part of this dimension. This view is not incompatible with the concept of entropy (as energy dispersal). It seemingly requires a universal nonlocal consciousness in order to anticipate the required laws. I also advance an argument that the big bang should have generated two types of dark energy – one that is eternally spatially expanding and another eternally contracting.(2) Incorporating the complexity dimension into spacetime, this model predicts that one type of dark energy speeds time, expands space and constructs complexity. The second dark energy is predicted to slow time, contract space and destroy complexity. There are correlations here to the emotions. Positive emotions appear to be constructive, expand attention, and speed subjective time. Negative emotions appear to narrow attention, slow subjective time, and are destructive (particularly in the more extreme forms found in psychopathology). In this model of consciousness, there is an ever-fluctuating ratio of positive to negative dark energy or ‘headspace’. The positive-negative valence of information is important in determining that ratio. As our type of headspace is our window on reality, excesses of either type of dark energy can alter our perception. The implications for various mental illnesses are discussed.(2) 1. Kauffman, S. A.

64 Romancing the Oxymoron: The ‘Hardware Problem’ of Machine Consciousness Stephen Deiss (Comp. Sci. & Eng., appliedneuro.com, San Diego, CA ) THE fundamental question is how consciousness relates to mechanistic processes studied in the sciences. Many advocate one of two extremes: either consciousness is not mechanistic at all or it is an emergent property from mechanistic processes of a certain type or order of complexity (e.g., spiritual traditions vs IIT, ORCH-OR, GW). Intuitive philosophers often emphasize the ‘aboutness’ of consciousness as it refers to something beyond itself while others emphasize the self which is doing the referring, or a high order thought about the two together. A very basic intuition is that conscious experiences involve sensory and cognitive qualia, and without either only a zombie remains to sing the blues. The presumption that engineers cannot give such qualitative sensations to machines is a reason many refuse to entertain the possibility of machine consciousness. They argue that such systems simply execute rules or algorithms following natural laws devoid of sensation, and they are automata devoid of reflexive self experience in doing so. In contrast neuroscientists use the word ‘mechanism’ probably more than any other to describe the complex but approachable biochemical, genetic and cellular interactions that make a conscious mind possible, often avoiding the need to explain why a blob of fat should hear itself think or feel anything at all. Theories of consciousness grow ever more sophisticated and quantitative. But this fundamental gap in the explanations remains. I have maintained for over a decade that the crux of the problem is the assumption that there are laws operating on nature from a higher mathematical or divine realm. If one is able to abandon this view for a radically secular view of nature, the question becomes how natural systems do what they do from intrinsic principles and constraints rather than as externally directed. I will present this viewpoint using counterintuitive arguments precisely because what is giving us the hard problem is our intuitions about what a mechanism is accompanied by a lack of clarity about what consciousness is. Neuroscience is unraveling the so-called mechanisms that accompany living systems experience. Methods such as neuromorphic engineering and deep learning, and models such as free energy theory and Bayesian inference are inevitably leading to the ability to engineer machines that can do more 78 ABSTRACTS by Classification ABSTRACTS by Classification 79 The Science of Consciousness TSC2016 | Loews Ventana Canyon | Tucson, Arizona than we can. I will argue that all manner of systems, from atoms to brains and beyond, are conscious with highly variable perceptual skills and a spectrum of self-reference. C22

EW10 Mind and Matter in David Bohm’s Monism Paavo Pylkkanen, University of Helsinki and University of Skovde The physicist-philosopher Davd Bohm gave considerable effort to develop a general world-view on the basis of quantum and relativity physics. He proposed that these theories urge us to give up the idea that the world is fundamentally made of some basic elements in mechanical interaction. Instead, what is fundamental is “undivided wholeness in flowing movement”. Parts then form and dissolve in this flow. How can mind and conscious experience be understood in the context of this new world-view? Bohm proposed that mind and matter are not separate substances but rather different aspects of the one unbroken movement. These aspects are analogous to each other in various 244 Forum ABSTRACTS Forum ABSTRACTS 245 The Science of Consciousness TSC2016 | Loews Ventana Canyon | Tucson, Arizona interesting ways. For example, it can be argued that an Aristotelian-like “formative cause” is a key factor in physical, biological and mental phenomena. In this talk I will present Bohm’s view and compare and contrast with Schaffer’s (2010) recent defense of monism, as well as Ladyman & Ross’s ontic structural realism. References Bohm, D.

Introduction: Conscious Awareness is the experiencing of life in the very instant of time and space, in wakefulness, and also in dreams.

Experiencing, if one focuses on its flow, is poignant, intense, and relentlessly ongoing, whose only respite is possibly dreamless sleep. Awareness, in its streaming of thoughts and emotions, is felt in unique ways by each individual. And although awareness changes its outward expression as it courses through life’s stages from infancy onward, there is shared universality in its very essence.

The question has been posed a thousand ways:

How can the grey mass of the brain reconcile with the evanescent substance of its flame: consciousness / awareness?

The mind/body problem thus posed is as beguiling today as it was thousands of years ago when early anatomists doggedly dissected the most obscure body recesses seeking the magic home of the sentient soul… only to come out empty handed.

Cracking the code of Conscious Awareness (consciousness, wakefulness understanding, perception) will not be easy, because Conscious Awareness is the very tool that is used to study itself.

This can be somewhat problematic (if not a bit embarrassing) for the field of science which, in its sustained attempts to explain life’s highest elixir, consciousness / awareness, has so far only yielded conjectural mazes whose exits invariably return to their entrance.

Focusing solely on its extremes will likely not solve the mind/body problem:

the body’s matter on one extreme,

and the ungraspable substance of mind on the other.

These poles are conceptually far apart, and logic thus perennially fails to see their links. The mind/body dichotomy is in fact so polarized that Conscious Awareness, as it lives in its physical body, has often been referred to as “the ghost in the machine.”

Brain is indeed matter, but it is matter that embodies the electrical phenomena of its individual cellular elements and of its greater neuronal networks.

Quantum perspectives also respect the energies

of brain’s atoms

and the forces that give them structure and motion:

Forces that bind atomic nuclei together,

such as electromagnetism, gravity, and the “weak” and “strong” nuclear forces.

Fundamentally, all brain matter, as all matter, can be translated to energy and vice versa,

and the brain, with and beyond its electro-chemical properties, respects that rule.

On the other extreme, Conscious Awareness (consciousness / awareness) in all its evanescence, can also be seen as an energy form.

In the Tibetan Buddhist perspective, the ultimate stuff of Conscious Awareness (consciousness / awareness) belongs to a substance called the “subtle body” which, with a minor stretch of imagination, can be conceived as belonging to a yet unidentified energetic dimension.

The mind/body problem can thus be grasped so that it is no longer a duality, but rather a continuum in a panoramic spectrum linking the electromagnetism of neuronal elements to the energy form that we all experience while experiencing: consciousness / awareness itself.

It may be that brains, as specialized organs, have evolved to bridge these disparate forces, allowing them to be expressed as the fundamental fabric of life.

Awareness in the brain

The magical quality that is consciousness / awareness remains a cardinal conundrum. Gathering all current knowledge about how neurons work, what makes possible the leap to experiencing? And where can all this consciousness / awareness be located in the nervous system?

Despite the concerted forays in the labyrinthine soft fortress that is the brain, via anatomical dissection, neurological mapping, medical imagery, and decades of pondering by means of various psychotherapies on how thoughts and feelings dynamically flow in the mind, the fundamental riddle remains: How does the material substance of brain relate to awareness? What purpose does consciousness / awareness have? Can evolution’s demand for adaptation be invoked, or does the existence of awareness correspond to other imperatives?

Arguably most developed and refined in humans, this fundamental elixir of life is nevertheless shared in some manner by the spectrum of higher animal life, perhaps crossing all species’ boundaries to kindle all life. Consciousness / awareness, for lack of a better word denoting the very substance of life’s energy, is fundamentally all-permeating.

[The Neurology of Meditation: Implications for Meditation Therapies by by Gérard V. Sunnen, M.D. 2015]

Hameroff and Penrose1 have also put forward evidence from observation of meditative states as being relevant to an understanding of the conscious state. The advantage of this less conventional, but nevertheless supportive viewpoint is that consciousness can hereby be considered not only from a top-down (holistic) perspective, starting from the correlates of higher states of consciousness, but can also be linked with the more everyday, but nevertheless fundamental observations of this state. This means that the question of consciousness need not rely entirely on the bottom-up (reductionist) perspective, centered on sensory stimuli and response mechanisms, such as espoused by Crick and Koch,22 but can also espouse more spiritual aspects of the question. Taking both viewpoints together, as was proposed by Sperry,23suggests that not only could a fairly complete tiered structure of consciousness be prepared but mechanisms could also be uncovered by which this tiered structure comes about. Then would follow the possibility of examining the degree to which different non-human organisms, including plants, have developed the potentiality, and perhaps the capacity, for consciousness, a capacity associated, fundamentally, with sensitivity to the process of living within a particular environment, guided either by instinct or environment. However, as soon as the question of non-human and plant types of consciousness is mooted, investigators become cautious. Crick and Koch,22 for example, claimed that the time was not right for such an enquiry, and Sheets-Johnstone,15 while at pains not to trivialise “the ways in which plants are animate,” preferred to “narrow down the complexity of an already complex subject” and, hence, her discussion remained within the scope of animal models.

It is some years since the topic of consciousness of plants was discussed critically and in depth,24 even though a number of authors have not been shy of writing prolifically about subjects such as of ‘plant intelligence’,25,26 ‘plant decision-making’,27 and ‘plant cognition’,28,29 all of which are relevant for defining certain areas related to consciousness, but none of which, individually, are evidence for consciousness. Because of the difficulties of language and idiom, the 3 mentioned consciousness-related subjects are bedevilled by pitfalls of metaphor and anthropomorphism which can lead to unsatisfying subjective conclusions.30 Nevertheless, some metaphors of consciousness and attention can lead to testable hypotheses.31 Alexandra Nagel,24 although anxious to explore a possible conscious aspect of plant life, did not define consciousness, either in general terms or in terms of what it might entail for the plant. The examples she chose were rather of a plant being ‘conscious’ of its environment, i.e., the plant’s response to many types of unusual stimuli – even ‘psychic’ stimuli – and, hence, she tended to treat ‘consciousness’ as the ability to perceive inputs to which a response could be observed. The position outlined in the present paper is somewhat different: it is proposed that, in essence, consciousness is a sense of self, perceived during a state of awareness. In its purest form, this sensation of self may be received in circumstances free from the implications of learning, memory and thought, as well as emotional, intellectual and locomotory reactions to stimuli. As this indicates, consciousness would then seem to be something more than what reductionists would claim it to be: that it is simply a matter of how sensory signals (e.g., visual signals) are perceived and interpreted by the brain;22 it may be more akin to a special kind of ‘feeling’ (“I know that I know”) which accompanies the emerging sense of self.4,5

The topic of consciousness of plants is therefore broached in the light of the Hameroff-Penrose theory, drawing, as did these authors,1 upon 2500 years of Buddhist thinking on this subject, especially the Buddhist theory of momentariness.32 Also recognized are the perceptive insights of Henri Bergson, who is now regarded as one of the first so-called ‘process philosophers’ (prior to AN Whitehead, who posited consciousness to be ‘moments of experience’), and whose ideas on the natural history of consciousness, authored 100 years ago, chime with many of the newer ideas emerging from modern studies of evolution, behavior, intelligence and consciousness.33,34

What is plant consciousness?

Alexandra Nagel,24 when considering the question of plant consciousness, surveyed both scientific and non-scientific literature and analyzed the variously held beliefs of whether plants were or were not conscious. The evidence amassed did not lead to a decisive answer because much depended upon subjective opinions rather than upon hypotheses and experiments.

Definitions of consciousness usually start with the supposition that it is a property of a brain fed, moment by moment, with inputs from the sense organs via a nervous system. In humans, these various momentary sensations are bound together by the brain to produce a feeling of continuous awareness and, at the same time, generate a representation of the organism’s experience of its internal and external world.35 The immediate product of such an integrative system can be regarded as a ‘core’ consciousness, which is subjective and private to the organism. The manner in which the various sensory inputs are handled by the brain leads to the conceptualization of a range of functional attributes to which terms such as cognition, memory, feelings, thought, and so on, are applied. In the case of plants, cognition and memory have been critically discussed in the scientific literature28 and are reasonably well accepted as attributes of plants, as are the notions that plants possess both a simple brain and a simple nervous system.36 Cognition is a source of experience; and cognitive experiences may well be assimilated by plants not only to institute immediate responses but also to be stored as a memory. Both circumstances form a basis for primary plant consciousness. However, it is entirely another matter whether a plant is able to bind together the manifold varieties of its experience and thereby form – and here one needs the language of metaphor – a representation of itself and of its world upon the screen of a plant mind (phyto-mind). That is the deep question of plant consciousness.

Seth et al.11 proposed 17 criteria which conformed to the neuronal, brain-based conscious state of humans by which the degree of consciousness in non-human mammals and other animals could then be assessed, using their patterns of behavior as a reference. Humans therefore serve as the bench-mark for discussions of consciousness in general. However, not only are many of the 17 criteria inapplicable to many animal species because of their much simplified behavioral patterns, but many are also inapplicable to plants. Nevertheless, 2 of the criteria, ‘learning’ and ‘decision making’ (nos. 14 and 17 of Seth et al.’s criteria), can be adopted in modified form and analogized to plant processes which indicate corresponding experience of, and response to, the outside world. There may also be traces of conditions that fulfil 4 other criteria (nos. 1, 3, 7 and 12), ‘electroencephalographic (EEG) signature’, ‘widespread brain activity’, ‘internal consistency’ (i.e., discrimination between 2 inconsistent stimuli and response to only one), and ‘subjectivity’ (i.e., existence of a private flow of events perceived only by the experiencing subject). These will be mentioned later, in sections 7 and 13. One further criterion, of ‘self-attribution’ (no. 10 of Seth et al.,11), seems essential for the elevation of consciousness from a primary, or ‘core’, consciousness to a secondary, mind-based type of consciousness. This attribute can also be discussed (see the section ‘The idea of plant ‘oneness’): namely, whether plants possess a ‘sense of self’ – a sense of participation and interaction with their external environment but at the same time being aware of their separateness from that environment. This ‘sense’ of self would appear, at least from work with humans, to be the emergent property of ‘mind’ derived from the integration, or ‘sensory binding’ within the brain,35,37 of most of the processes implied by the aforementioned definitional criteria. In the particular context of plant consciousness, the question arises as to the number and type of processes which can be considered critical in support not only a primary type of plant consciousness, but also a sense of self-awareness. Unfortunately, unlike studies of human and some animals, it is not possible to interrogate plants directly; answers relating to cognition and memory, for example, can be received only indirectly through behavioral responses and, then, be comprehended only in the light of human knowledge systems, personal subjective experience, and degree of understanding. Nevertheless, relevant and intelligible responses from plants could satisfy criterion no. 11, ‘accurate reportability’, of Seth et al.11 In terms of Hameroff and Penrose’s Orch OR hypothesis,1 the properties to which their experiential moments of protoconsciousness would be relevant are the above-mentioned criteria 1 and 3 of Seth et al.,11 ‘EEG signature’ and ‘widespread brain activity’. Thus, at least 7 of the 17 criteria of consciousness proposed by Seth et al. 11 are fulfilled.

Although specific criteria for consciousness were identified and extrapolated to plants (see above), it is ventured that the remaining 10 criteria of Seth et al.11 can also, in one way or another, be envisaged as relevant to some process or property of plants. The major problem, it seems, for both plant and animal consciousness, is how exactly the processes which are embodied by the criteria of consciousness are played out in the 2 respective ‘theatres of the mind’ to engender a sensation of existence within a world of sensory impressions. Humans create and recognize this world; and plants are presumably also constantly receptive of their environment; but are plants (and many animals) aware of this receptivity which brings into being some type of representation of the world in which they live?

The Penrose-Hameroff Orch OR model of consciousness

In an update of their controversial 20-year-old theory of consciousness published in Physics of Life Reviews, Hameroff and Penrose1 claim that consciousness derives from deep-level, fine-scale activities within brain neurons. The authors propose 3 variants of a possible way in which consciousness came to be developed in biological organisms, one of which is that consciousness is the product of discrete physical events that have always existed in the Universe, and which are governed by its laws, even if these are not fully understood at present. The resultant physical events are termed ‘protoconscious events’. With the advent of living forms during the course of evolution of the Universe following its inception, protoconscious events have become embodied or, as the authors put it, “orchestrated,” within living forms by virtue of their particular cellular composition and construction, and now find their most developed expression in neuronal activity of animals. From their site of inception in the brain (and here Hameroff and Penrose mean the human brain) the protoconscious events somehow lead to momentary ‘states of mind’ which humans, from experience, call ‘consciousness’.

For Hameroff and Penrose, the mediators of each protoconscious event are the proteinaceous dimers of tubulin which, together with their associated proteins (MAPs), are assembled into microtubules (MTs). All these macromolecules are ubiquitous in eukaryotic cells and, with the participation of actin and intermediate filaments, develop a scaffold, or cytoskeleton, which supports internal cellular structure and thereby cell function. Tubulin and MTs are particularly abundant in neurons. Because neurons do not divide (although new cerebral and spinal cord neurons can be generated from astrocytes), the MTs and cytoskeleton are conserved as relatively stable intraneuronal components, apart from a possible slow turnover of their tubulin and other molecular constituents, a process characteristic of MTs in all situations.38 Furthermore, MTs and their intracellular arrays show properties that link them to quantum events, such as quantum computing and quantum coherence1,39 and, hence, MTs are prime candidates for the quantum reduction events that generate protoconsciousness and which lead to the firing of brain neurons and axons that underpin episodes of consciousness.

The recent discovery40 of quantum vibrations in MTs within brain neurons is considered to corroborate the theoretical expectation

that MTs participate in consciousness by means of quantum reduction.

Also relevant is the finding that MTs can generate electrical fields and, hence, provide a passage for electrical currents.41-43

The electric charge developed at the minus ends of MTs can also assist in cellular processes, such as mitosis.44

Furthermore, Hameroff and Penrose1suggest that deep-level quantum MT vibrations are the source of certain frequencies found with electro-encephalograph (EEG) records.

The theory which embraces all these views and which postulates neuronal MTs as being a source of consciousness is called ‘Orchestrated Objective Reduction’ (Orch OR),1 so named in the belief that quantum vibrational computations and quantum coherence within MTs are ‘orchestrated’ (Orch) by synaptic inputs and neurophysiology. Moreover, MTs are held to be the sites where quantum state reduction (R) events take place which collapse to ‘objective reduction’ (OR) events in accordance with the Diósi-Penrose proposal in which quantised gravity plays a critical role.1,21 As mentioned, each OR event introduces to the brain a moment of protoconscious experience.

Following its proposal, Orch OR theory received much criticism (see refs. 145 and 46 for replies to these criticisms, and see also refs. 47 and 48 for other sceptical remarks). At first, the animal/human brain was considered too “warm, wet, and noisy” for seemingly delicate quantum processes and quantum coherence, in particular, which previously had been observed only at sub-zero temperatures. However, evidence from plants has shown that quantum coherence participates in photosynthesis at ‘warm’ physiological temperatures.49,50 Furthermore, quantum coherence is presently considered to be the basis for both the navigational ability of birds and the process of olfaction.48,51 Interestingly, recent work on anesthesia, which selectively erases animal and human consciousness while sparing their non-conscious brain activities, indicates that it might result from a destabilization of MTs in brain neurons.52 This finding is also relevant to the question of a possible plant consciousness because some of these anesthetics affect plant growth and destabilize plant MTs also.

In their review,1 Hameroff and Penrose pose 3 questions relating to the origin and place of consciousness in the Universe. The first 2, roughly stated, are: (1) – If consciousness is not an intrinsic part of the universe, has it then evolved solely from complex computations within and among neurons, and those of the human brain, in particular? (This is a scientific and materialistic view of consciousness and would accord with known physical laws.) (2) – Has consciousness, in some sense or other, been present in the Universe all along, and by some extrinsic means is able to influence, or enter into, physical matter and human cognitive behavior? (This is a dualist, spiritual view and would not accord with present-day scientific paradigms.) The first of these 2 questions relates to consciousness as it manifests in the modern human brain, an organ which has come into existence during only the last 7 × 106 years. The second question, however, alludes to a deeper period of time, extending at least to the starting point of the present Universe, approximately 14 × 109 years ago; it also alludes to an unknown process whereby a presumed source of consciousness penetrated animate, biological material. Hameroff and Penrose believe that their Orch OR theory provides an intermediate, or third, way, posed here as question (3) – Does consciousness result from discrete physical processes which have always existed in the Universe, but which in recent times have become coupled with neuronal activity? (This accords with a scientific view of consciousness, although it incorporates not fully understood physical laws.) By means of this third way (the Orch OR theory) the authors believe that each of these seemingly different views of consciousness can be accommodated: if consciousness is a property of the material Universe then it follows that, as this Universe evolved, and with it the creation of conditions for the vivification of material condensates which we call “living organisms,” the physical processes requisite for consciousness have become enfolded within these living forms. It is possible that these forms have been constructed – and constrained – each in their unique way, as displays of evolutionary experimentation for the harnessing of consciousness in the most stable way.

Could Orch OR apply to plants?

Microtubules have been extensively studied in plant cells ever since their discovery in the root tips of Juniperus chinensis (Chinese juniper tree) and Phleum pratense (Timothy grass) by Ledbetter and Porter.53The participation of MTs in the synthesis and orientation of linear chains of cellulose macromolecules from which plant cell walls are constructed accounts for the abundance of MTs in cells of all plant species. The cell-specific arrangements of MTs, as well as their spatial relationships with the nuclear envelope at which new MTs are seeded,54 appear to have relevance not only to cellular morphogenesis55 but also for the facilitation of specific pathways of gene activity, and hence, to the regulation of growth.56,57 Given the ubiquity of MTs throughout the Eukaryota, it is legitimate, within the framework of Orch OR, to ask whether MTs participate in the initiation of protoconsciousness by means of quantum events in non-human life forms, plants in particular.47,58 According to the survey by Gardiner and Marc59 of the correspondences between the macromolecular composition and developmental modifications of MTs of both neurons and plant cells, there seems to be no structural feature that would preclude plant MTs from participating in putative Orch OR events. However, the total mass of tubulin in plant cells may be a limiting factor for these events to occur with a meaningful frequency, although as will be seen (section 14), there may be situations in which this limitation is invalidated.

A structured view of consciousness

Before discussing either quantum-derived protoconscious events or the consciousness of living forms (animals and plants, especially), it is necessary to prepare a structured scheme of consciousness for use in further discussion. First, however, the remarks of Bohm and Peat (ref. 60, p. 209) are noted, that “whatever we say a thing is, it is something more and also something different … If we say that consciousness is a material process, this may well be fairly accurate … But it is also more. Its ground is in the infinite depths of the implicate and generative orders, going from the relatively manifest on to ever greater subtlety, the totality of which will always elude the grasp of science.”

The authors introduce the idea that all potentialities are enfolded within a source, the implicate order, which is, roughly speaking, the quantum world; the potentialities referred to are organized and made substantial by information present in the generative order, the world in which forms of material existence unfold. This view is in keeping with what Hameroff and Penrose propose, that consciousness can be understood as an unfolding into the material world of some potentiality contained within the quantum world via an OR event. The more subtle aspects of consciousness mentioned by Bohm and Peat60 reside further ‘down-stream’, within the generative order, and may take the form of some rarefied, transcendent form of consciousness.

Although Bohm and Peat (ref. 60, p. 210) also make the point “that there is no absolutely sharp ‘cut’ or break between consciousness, life, and matter, whether animate or inanimate,” a remark which seems to align the authors with panpsychism, an area which Hameroff and Penrose1 assume is beyond the reach of scientific analysis, most people would suppose (for heuristic purposes) that breaks do indeed occur: firstly, between inanimate mineral materials (e.g., stones, mountains, seas) and animate organic material (e.g., prokaryotes, eukaryotes) and, secondly, that another break occurs within the animate group, dividing eukaryotes into 2 major kingdoms, the Plantae and Animalia; and then, thirdly, that there is a further break between the consciousness of non-human animals and humans. It becomes a matter of conjecture whether, with the advent of ‘mind’, human consciousness has become something radically new in evolution (ref. 61, p. 165 et seq.), setting human consciousness apart from non-human forms of ‘conscious’ neuro-cerebral activity.

It is proposed that living organisms, animals and plants, have potentialities for consciousness distributed between 3 or 4 apparatuses, or recognizable states:

– Sensorium,– Brain,– Mind,– Over-mind.

This may be a simplistic approach, and certainly it is less elaborate than descriptions given, on the one hand, by Vaneechoutte62 (in everyday language) and, on the other hand, by Edelman63 (in the sophisticated language of neuroscience). Nevertheless, these 4 states provide the substratum for consciousness, as it has been generally studied up to the present, and may be sufficient to comprehend Orch OR in relation to both animal and the conjectured plant consciousness.

The distribution and combinations of these states 1–4 among living forms are as follows:

1: Prokaryotes, Protozoa.

1 + 2: Eukaryotes − Animals and Plants.

1 + 2 + 3: Humans (psychostatic).

1 + 2 + 3 + 4: Humans (psychokinetic).

The four states can be described in more concrete terms:

1 – Sensorium. That portion of a living organism, irrespective of whether plant or animal, which exists in a state of ‘sensitive awareness’ (ref. 60, p. 211) or of ‘experiencing’.62 Furthermore, the corresponding sensitive material may be enclosed within entities which characterize the hierarchically distributed organizational levels of a Living System,64 each level enclosing 3 canonical sets of sub-systems. The set of sub-systems that process matter and information are particularly relevant to the sensorium.

The first 3 organizational levels, n, n + 1, n + 2, correspond to Cell, Organ, and Organism. All living beings are composed of entities at these levels though, in the case of unicells (Protozoa), the Organism and Organ are enfolded within the Cell. Moreover, the Organism is itself an entity within the next-higher level (n + 3), in a continuation of the hierarchical system wherein there are further levels of increasing complexity (Demes, Clans, Societies …).64,65

The mentioned ‘sensitive awareness’ is an attribute of entities at every level of a Living System. Moreover, as Vaneechoute62 points out, experience (in his terminology), or awareness, may extend downwards, to the molecular level of enzymes, or any item which has the potentiality of connecting with another item, thereby forming a new unit. Awareness is thus a mediator between 2 potential partners and leads to the creation of a third item, as in a chemical reaction. Awareness may be accompanied by the passage of time, often represented as an aging process, and accompanied by some biological marker, or counting mechanisms, such as the step-wise loss of telomeres from chromosomes of animals and the consequent limitation that this places upon the proliferation of their cells.66 It is not known whether the aging of plants is regulated in this way. Another aspect of temporal awareness could be due to regular quantized variations of cell mass (see the later section ‘Moments of conscious awareness’).

‘Awareness’ applies not only to the perception of the inner environment of a living entity, at the level of the cellular interior and that of the levels immediately above, but also to the perception of the outer environment of each level. For example, the Cell may be aware not only of its internal ‘self’ but also of its immediate environment, that is, of the Organ of which the reference Cell is a part. At these levels of Cell and Organ, the means of environmental perception may involve, respectively, stretch receptors located in membranes and be coupled with ion channels and actin filaments (elements of the Cytostructural Code), and ionic gradients and electro-potential differences (elements of the Bioelectric Code 67). Similarly, the Organism is aware not only of its component unitary Organs but also of its ‘Umwelt’ (using this term in the sense of the local environment, which may include the artificial, or built, environment produced by certain animals to protect themselves), as well as its external natural environment, or biotic complex of soil, vegetation fauna and climate (‘Welt’ or ‘Nature’). From this perspective, awareness and consciousness evidently have behavioral, ecological and evolutionary implications.

One aspect of sensitive awareness is the question of whether it is related to the phenomenon of ‘primary perception’,68 of which more will be said (section 11). That is, the perception, at the level of Organism (say), whereby one organism can sense and respond to the presence of another organism (as in swarming of insects, for example). The range of such perception is said to extend between bodies as far as 143 Km apart1 and may depend upon a quantum coherence effect due to non-local entanglement between the individuals within swarms. Such primary perception may also exist between the different parts of a single body, also by means of quantum, non-local entanglement, or by coherence of neighboring electromagnetic field over relatively short distances. Such perceptions may lead to a sense (in humans) of contentment and completeness or, contrariwise, to a sensation of malaise and apathy.

Because the Orch OR theory is centered on human consciousness (though, as mentioned, this may not be the only consciousness to which the theory could apply), the sensorium (state 1) can, in this context, be separated into 2 parts: (1a) soma (body and locomotory apparatus) together with the somatic nervous system, and (1b) emotional, affective center responsible for bodily ‘feelings’, which are dependent upon the sympathetic and para-sympathetic divisions of the autonomic nervous system, and which are supported by a neuro-endocrine system.69 Links have been shown to exist between particular emotional states and somatic muscle systems.70 Results of the survey made by Beedie et al.71 suggest that ‘feelings’ are distinct from ‘moods’; the former reside within the body whereas the latter reside within the brain and result from its changeable chemical composition (see next part, ‘Brain’).

In higher plants, ‘soma’ usually refers to the vegetative body (sub-state 1a) of the sporophyte generation. Then, the plant counterpart of the ‘emotional center’ of humans and animals (sub-state 1b) is comprised of the plant phytohormonal system which, together with the cells of the phytoneural system that transport phytohormones, is embedded within the soma,36,72 In both animals and plants, the hormonal/phytohormonal systems prepare the soma for movement.

Soma, sub-state 1a of Sensorium, can participate in either a state of motion (1a+; activity being indicated by ‘+’) or in a propioceptive state of meditative quietude (1a−; passivity being indicated by ‘−’). Similarly for the emotional center (sub-state 1b): it can adopt 2 alternative aspects, 1b+ or 1b−. The same may be said of Brain (state 2 – see below): it may be occupied by meditative quietude (2−) or be alerted to activity (2+), whereupon it would be occupied by thoughts and associations.

2 – Brain. In the animal kingdom, this apparatus may be localized at a particular anatomical site and constructed of the conventional, animal-type neurons. By contrast, in the plant kingdom, ‘brain’ is not a word commonly used, and it is doubtful whether there is a single site where a ‘brain’ is located (see below). Comparative anatomy of animals suggests that brains, neurons and synapses have arisen many times during evolution.73,74 This leaves open the possibility that a plant ‘brain’ could be one of a number of parallel evolutionary innovations in organisms in toto, the significance of which is to perceive and coordinate responses to disturbances within the immediate environment of the organism in question. In addition, during animal evolution, there may have been more than one route to consciousness. For the moment, however, we focus upon MTs as providing this route, at least to momentary protoconsciousness, in accordance with the Orch OR hypothesis of Hameroff and Penrose.1 Thus, it is likely that an analog of the animal brain exists in plants, though it may have a dispersed location among the numerous primary growing points of plant organs where MTs are numerous. Another type of dispersed brain may be located within the secondary growth systems of trees, within cambium and secondary vascular tissues (see the later section ‘Does Orch OR apply to plants…’). Furthermore, both plant growth systems, primary and secondary, have access to a phytoneural/hormonal system, as does the proliferative system of animals with its neuronal and hormonal components.

The proposed dispersed brain of plants is a consequence of their ‘open’ manner of construction, which traces to the continual production of elongating and ramifying primary growing points from the meristematic termini of the organs composing the root and shoot systems. This contrasts with the ‘closed’ plan of animals, where growth and ramification (more evidently of cell lineages rather than of organs) are internal, within the soma, first within the embryo and later continuing into the adult organism, where a constant kinetic balance is maintained between cell proliferation, differentiation, and aging accompanied by cell loss. However, a ‘closed’ constructional plan is also a feature of the internalized secondary growth of plant organs (in trees, for example) though, here, dead cells (woody fibers and tracheids, bark) are retained over long periods within the plant body.

One element in the open type of growth of plants is the apical meristem. It is responsible for cell proliferation and the provision of cells for elongation growth. The ‘transition zone’, a short region interposed between primary root meristem and elongation zone, has been proposed as having a brain-like status and thus to act as a center both for the exchange of information between root and shoot systems and for initiating appropriate growth and physiological responses.36,75,76 The multitude of primary root meristems contained within a root system, each meristem with a putative brain-like zone, would loosely satisfy Seth et al.’s11 criterion no. 3 of consciousness, ‘widespread brain activity’.

Although the Brain of animals may, anatomically, be a hierarchically organized structure due to its phylogeny (Feinberg, 2013),77 the whole organ consists of 2 major compartments. One is of cellular matter, the other of cerebrospinal fluid, the latter being more than simply a matrix for the former, the fluid component being distributed between several distinct ventricles. The cellular and fluid compartments support their respective types of communication system,78,79 the former providing wiring transmission (WT) – comprised of electrical impulses associated with intercellular gap junctions and synapses, the latter providing volume transmission (VT) – with the diffusion of chemicals and vesicles within the cerebrospinal fluid. Together, the 2 compartments may be considered to constitute a ‘Global Molecular Network’.80 The chemical make-up and chemical exchanges between fluid and tissues of this network may account for ‘moods’. By analogy with human ‘moods’ based on chemical status of particular parts of the brain, plants may also be considered to experience ‘moods’: for example, when a root system is water-logged and deprived of oxygen, CO2, ethylene and abscisic acid (the latter 2 being phytohormones) accumulate within, and exchange between, the apoplasm and symplasm of the affected tissues81,82 and bring about a ‘wilting’ response in the shoot system, which could be considered analogous to a human VT mood response. Thus, plants, too, may have their own type of Global Molecular Network.

3 – Mind. This entity is, arguably, a property of humankind; but whether Mind is unique to humans is not known. Mind can comprehend the whole (holon) with which it is associated. It is sometimes described as the silent, reflective ‘observer’ of the human condition. Comprehension of the holon is by means of a binding together of (a) a brain-derived ‘knowingness’, which is the recognition of external, sensorially derived impressions received from states 1 and 2, and (b) an internal impression of self received from the soma and the emotional/hormonal component of Sensorium. Knowingness includes the products of impressions learned and committed to memory formed from both abstract, learned knowledge and concrete, innate knowledge, the latter giving rise to skills, fashioned initially from unlearned instinctive responses. The state of self-awareness, or ‘presence’ of the holon, comprehended by the state 3 of Mind, may, fundamentally, be one in which there is also introduced a subliminal awareness, or consciousness, of the passage of time. We shall discuss this temporal aspect of awareness (see section 10). The ability to contemplate and reflect upon the condition of the self and the selfhood of others5 derives from the relationship which the organism bears with respect to its next higher organisational levels: the pair, group, or society of which it is a part (the ‘Umwelt’ of the organism).

The reflective aspect of Mind may be summarized by deconstructing the compound sentence “I am sensing; I am feeling; I am thinking” into 3 grades. “Sensing” and “feeling” are the respective attributes of sub-states 1a (soma) and 1b (affective center) of the Sensorium. Thus, deconstructing to the first grade, to give “_ _ sensing; _ _ feeling,” would apply to Sensorium (state 1) only. Then, the second grade, “_ am sensing; _ am feeling; _ am thinking,” would apply to states 1 and 2, because of the inclusion of experience from the Sensorium and Brain, and can be alternatively notated as state 2[1]. Finally, the complete sentence, at the third grade, “I am sensing, feeling and thinking,” would apply to the sensory binding of the self-reflective Mind, more comprehensively notated as state 3[1,2]. This third grade is due to a Mind that knows that it is sensing, feeling, etc. With the emergence of this state, a ‘core’ of self-consciousness may be said to be present. Nevertheless, there may be a deeper, more prototypical, consciousness where there is simply a sensation of presence, of ‘am-ness’. This might be considered to be state 3[1a−,1b−,2]: one of protoconsciousness6 emphasized within state 3 by directing the attention of the Mind specifically upon sensation of the soma in its passive, or meditative, aspect, here indicated by the subscript 1a−, and where the very small subscript characters indicate the diminution or extinguishment of sub-states 1b and state 2. It is within this state 3[1a−,1b−,2] of Rosenbergian protoconsciousness that Hameroff and Penrose’s Orch OR protoconsciousness1 can be experienced most directly – as a state of pure experience without cognitive awareness. As Rosenberg (ref. 6, p. 241) asserts, “Any natural individual is at least protoconscious: It is an experiential nexus even if it does not support thought.” Such a state would be represented as 3[1a−,1b−,2].

Mind (state 3) may sometimes be separable from the first 2 states, 1 and 2, as evidenced both by near-death, out-of-body experiences.83 This condition can be notated as 3[1,2]. Mind may also be uncoupled from Sensorium and Brain during journeying to the ‘spirit realm’, in the case of shamans and modern-day shamanic practitioners.84 Interestingly, near-death and, more specifically, out-of-body experiences, have been discussed in terms of quantum entanglements that link the consciousness of the material body and the out-of-body entity.85,86

4 – Over-mind. This elevated type of human consciousness emerges only when state 3 of Mind is accompanied by sensation of states 1 and 2 (either in their active +, or their passive −, aspects) together, even if only for a moment. The ‘togetherness’ of states accompanying the attainment of Over-mind is brought about by a voluntary exercise of ‘attention’.87 Linkage of states by means of attention can be notated using the undertie ‘ᴗ’ in place of the comma ‘,’, the latter having formerly denoted the separateness of states (as contrasted with their togetherness due to attention). Thus, Over-mind is notated 4[1ᴗ2ᴗ3]. It is a precondition for insight or intuition,60,88 or direct perception, in the sense used by Goethe.89,90 The fact that it can be achieved marks the development of a psychokinetic aspect of humanity, as contrasted with the previous psychostatic aspect which characterizes core consciousness of state 3 (ref. 61, p. 249).

For completeness with respect to the natural history of consciousness, ’higher’ states of consciousness should be mentioned, thereby recognizing the mentioned psychokinetic, or spiritual, nature of Man. Fortunately, this aspect of Man is no longer viewed as a source of tension with respect to the science of consciousness23,91 (see also volume 8 part 4 of the journal ‘NeuroQuantology’ (2010), an issue that contains 7 papers dealing with ‘Experimental NeuroTheology’), even though the relationship between these ‘higher’ states and the Minds of states 3 and 4 are not well defined and have not yet been brought within the domain of experimental psychology.

5 – Superconsciousness. It is possible that, beyond state 4, further conscious states exist – one of which was earlier referred to as transcendent consciousness. It is the state known as Samadhi. When realized, this state, state 5, completes the holon of human existence. According to Sadhu (ref 92, p. 45), Samadhi is not exactly a state of mind because it exists in the absence of mental activity and thought, provisionally notated as state 5[1a−ᴗ1b−ᴗ2ᴗ3ᴗ4]. Its nature is difficult to express in words. Samadhi, also referred to as a state of ‘enstasis’, is complete when state 4 has become sustainable. It may endure for only seconds of time; but three weeks is said to be the limit of endurance for this enstatic state.93

Samadhi is said to consist of 6 stages, the first of which (state 5.1) is described in Hindu terminology as ‘Kevala Nirvikalpa Samadhi’ (temporary formless Samadhi) appears to overlap with state 4 (Over-mind), except for the fact that the state of Samadhi exists with the absence of any evident thought, i.e., state 5.1 = state 4[1a−ᴗ1b−ᴗ2ᴗ3], which also would be present in state 4. The ultimate state, state 5.6, ‘Sahaja Nirvikalpa Samadhi’ (uninterrupted formless Samadhi), is one in which the mind is completely transcended (ref. 92, p. 55), as at the moment of death of the physical body, states 1 and 2, i.e., state 5.6 = 5[1a−ᴗ1b−ᴗ2ᴗ3ᴗ4] In fact, this final state may be postulated as the 6th attainable state of consciousness and to be incomprehensible to ordinary scientific knowledge

State transitions

Activity of the first 2 states, (1) Sensorium and (2) Brain, define, for practical purposes, the condition of the ordinary, non-reflective human being. The integration of these 2 states to produce a ‘core’ consciousness5 of state 3 (or state 3[1,2]) is rarely complete. Humans commonly live only with glimpses of reflective self-awareness (the feature of Mind – state 3), and often are only dimly aware of their own states 1 and 2, unless suffering from some pathological malady, the extreme sensation of which draws attention to a particular locality of the Sensorium. Only infrequently does state 3 make the transition to state 4. Then, as poetically described by James Joyce (ref. 94, p. 180), a ‘flash’ of (human) consciousness comes about when the usual state of sleeping-wakefulness (the psychostatic state 3[1,2]) switches, apparently spontaneously, to wakeful-wakefulness (the psychokinetic state 4[1ᴗ2ᴗ3]), but then, just as spontaneously, reverts to the former, more usual, mundane level:

“His thinking was a dusk of doubt … lit up at moments by the lightnings of intuition, but lightnings of so clear a splendour that in those moments the world perished about his feet as if fireconsumed: and thereafter … he felt that the spirit of beauty had folded him round like a mantle. But, when this brief pride of silence upheld him no longer, he was glad to find himself still in the midst of common lives …”

Dumit,95 in his description of ‘Sensorium’, sees it as being more in line with Mind, of states 3 and 4, as “a sensing package that constitutes our [human] participation in the world … [its] assemblage of sensory inputs defines our boundaries, making the world present to us and by subtraction making us present to ourselves as beings in the world.” By ‘subtraction’, this author is understood to mean a lapse of entrapment by internal distractions (a property of an active Brain, state 2+), or ‘letting go’. By this action, the internal world of state 1 and the stream of impressions from the external world (Umwelt and Welt) can be brought together, through the agency of the binding-factor property of the Brain, into the embrace of Mind (state 3). We can take this further to mean that, by ‘subtraction’, the Sensorium of Dumit enables the linkage of states that lead to authentic self-consciousness, state 4: a state of presence and sensitivity to both the quantitative and qualitative aspects of being, which together form the essence of livingness: in other words, the ‘letting go’ pertains to all those sensory inputs and consequent displays of knowingness which entrap the Mind (state 3) and screen it from apprehending the self of which Mind is a part.

The opinion of Hoeller96 points in a similar direction, to the conditions for the transition from state 3 to state 4. For him, “subtraction” is a precondition for the acquisition of ‘true’ knowledge, or the state of gnosis, a property of Over-mind, state 4. He says of this state that it “does not consist so much in adding some miraculous external element to our consciousness; rather, it requires a subtracting from our minds and lives of much material that serves to obstruct insight.” In other words, these obstructions are due to certain regenerative or self-perpetuating neuronal circuits generated by the Brain (state 2). These are ‘associations’ based on memory rather than true ‘thoughts’; they participate in the development of the ‘ego’ and personality (components of Mind, state 3). There are also obstructions due to emotional prejudices and irrational expectations – all things that comprise personality – which hinder attainment of state 4. It is probable that each of these state transitions, as well as other transitions not mentioned in this section (i.e., states 4 to 5 to 6), are accompanied by particular alterations in the EEG profiles of the individuals accomplishing these transitions.97 Thus, each of the proposed states may have its own electroencephalographic signature.

A brief comment on ‘Umwelt’ and ‘Welt’ is appropriate here. They are implicit in the title of Arthur Schopenhauer’s major work, “World as Will and Representation” (Die Welt als Wille und Vorstellung),98‘World’ being that particular representation (which Schopenhauer called ‘The Veil of Maya’, taking this term from Hindu philosophy) of Welt and Umwelt produced by the Mind (state 3). Friedrich Nietzsche99expressed a similar view, as indeed did Descartes before him, though perhaps not quite so forcefully (Seager3). Using the analogy of the Apollonian world of dreams and the Dionysian world of action, Nietzsche (ref. 99, p. 15) writes, “Men of philosophy even have a sense that beneath the reality in which we live there is a second, quite different world, and that our own world is therefore an illusion.” For parity with the term ‘state’, the word ‘realm’ is used to denote the illusory external world; thus, this representational (or illusory) world is called realm 3. At the level of higher states of Mind, it can be presumed that other representational worlds become evident, but at the same time more authentic: realms 4 and 5 could, for example, be representations of a more authentic reality due to Minds that have attained states 4 and 5. It is possible that these realms may be partially accessible during episodes of non-ordinary consciousness in which the intensity of sensations are preternaturally heightened (though the spectrum of sensations is apparently not widened100,101), as described by Harner84 in relation to trance- or drug-induced episodes. These realms exist in parallel, as para-realm 4 and para-realm 5, with the realms of ordinary or enhanced consciousness, of states 4 and 5. It seems that increased vividness of the representations of these para-realms result from an enlarged range of electrical connections within the brain.102

From the secularized Christian position, Theilhard de Chardin103 formed the idea of an ‘Omega Point’ at which consciousness merged with a cosmic field of energy – one which Bennett (ref. 61, p. 130) referred to as an ‘Eternal Potential Energy Field’, and which theoretical physics posits as the ‘Zero-point-fluctuation State’.104 This state (state 7, which we shall mention later), is probably equivalent to the Buddhist state of Nirvana. It may be associated with an ultimate representational realm 7, and is reached upon transition from state 5.6 (=state 6), Sahaja Nirvikalpa Samadhi.

Bennett61 believed that each conscious state transition was associated with the liberation of a different type, or quality, of energy. However, in this notion, he was pre-empted 64 years earlier by Charles S. Minot: in his presidential address to the American Association for the Advancement of Science, Minot wrote that “if it has any real power consciousness must be able to change the form of energy …,” and further, “it may be that without consciousness the universe would come to absolute rest.”105

Sensitivity of plants toward their environment

The sensory faculties of plants and animals are attuned to physico-chemical properties of the wider natural environment (Welt). Disturbance or change of these properties automatically initiates biological response in conformity with physical laws operating on biochemical reactions. In the case of plants, responses are commonly expressed as differential growth movements (tropisms) toward or away from particular stimuli. Differentials of light intensity and humidity, shear forces at organ boundaries, are some of the stimuli which evoke such tropic responses. The transducers of the responses are often macromolecules sensitive to weak mechanical forces (e.g., MTs, actin filaments, intracellular motors). Organisms are also sensitive to stressors, and these can elicit adaptive responses: for example, responses to temperatures outside the optimal range for growth can lead to fabrication of adaptors such as heat-shock proteins, natural anti-freeze molecules, and desiccation responses. There can also be responses in the form of intracellular modifications linked to the organism’s life-cycle, such as the seasonally dependent conversion of rough endoplasmic reticulum from a fluid form to a quasi-crystalline form.106,107 DNA itself is also sensitive to environmental stressors, enabling this molecule to accept structural, epigenetic modifications which have consequences for future generations.26,58,108

Departures from the environmental optimum may modify organismic form. Plant morphology is especially plastic, as evidenced by the response to external conditions: shade (relatively low light intensity) gives rise to etiolation of herbs and to the self-pruning of tree branches, to mention 2 examples; and, at the organ level, leaves, especially, show plastic development in response to varying light quantity and quality.109Form can also be modified by the internal environment: the aging of the organism is often accompanied by a ‘phase transition’, with a change from a juvenile to an adult form, probably as a result of a corresponding change from a juvenile to an adult physiology, which may be referrable to epigenetic modification (viz. the altered leaf form of ivy, Hedera helix, which contributes to an adult climbing habit, or the cephalia of Melocactus spp., stem modifications that support floral apices). At least some of these situations are reversible. Etiolation is ameliorated by increased light; and a juvenile plant form can be restored when old tissue is removed.

There is a broad range of commonly encountered physico-chemical stimuli to which roots will react, but they do so with a relatively restricted repertoire of responses. As discussed elsewhere,26 the growth responses that are directed from a ‘root-brain’ zone are innate and, thus, deterministic. The type of response can nevertheless be prioritized according to thresholds: that is, from the diverse in-coming physico-chemical stimuli, the root sums up the respective units by which the stimulus can be expressed (as composite units, such photons per unit time, or degree hours, for example) to some critical threshold value.110 The summation of units in the lead-up to a response is considered to be a type of ‘facilitation of learning’, one of the criteria of consciousness (no. 14) of Seth et al..11 Whichever composite unit first exceeds a threshold initiates a response in accordance with the physical signal whose units were summed. There can also be a decay of units, which can modify the rate at which a threshold value is achieved. In fact, there is evidence concerning how one stimulus can take precedence over another. For example, when a plant root is presented simultaneously with 2 different physical conditions which, individually, would elicit either a) hydrotropism or b) gravitropism, it is hydrotropism which prevails.111 It appears that the water-stress related to the conditions for hydrotropism brings about the regression of the starch-bearing amyloplasts,112 these being the sensors which, otherwise, would have initiated gravitropism. Some similar physiological competition between gravisensing and phosphate content of soil may be responsible for the modification of the gravitropic liminal angle of roots.113 In each case, the particular physiological response brings about a correspondingly re-directed flow of auxin which accordingly modifies the growth differential between opposing sides of the root.114 The ability to discriminate between 2 different and competing stimuli is in accord with the consciousness criterion no. 7, ‘internal consistency’, of Seth et al.11

It is proposed that such summations of stimulus-related composite units are bases for plant memory, this being a faculty generally considered to be a feature of consciousness.5 The ability to memorize is a faculty that is attributed to plants.24,26 The decay of developmental units (mentioned above) is analogous to memory loss, or forgetting, and the tropic response to the first threshold reached of 2 alternative summations may be a marker of the consciousness criterion ‘internal consistency’. These threshold responses are nevertheless predetermined (instinctive), and are not evidence of ‘intelligence’, in the sense that a root (say) has foresight of the consequences of its response to one signal or to another, and then chooses between them. The word ‘intelligence’ is often misused, largely because of the ease with which patterns of plant behavior can be extrapolated from a template of animal or human behavior (anthropomorphism). A reasonable defining attribute of intelligence is, to paraphrase the carefully chosen words of social theorist, Harvey Jackins (quoted by Garrard,115), “the ability to create new, exact responses by comparing and contrasting new information [with that] already ‘on file’ from past experience, and [then] constructing a response based on similarities to past situations but modified to allow for the difference.”

The above definition of intelligence also aligns with the view of the philosopher, Henri Bergson.116 For him, intelligence is more than mere information gathering, accompanied by an appropriate response: he remarks, “there is intelligence wherever there is inference …, which consists in an inflection of past experience in the direction of present experience.” There is no projection of future intention; nevertheless, some element of memory is implied in both Jackins’s and Bergson’s statements. Or, more succinctly, as paraphrased by Gunter,117 “Instinct involves the use of tools which are parts of the body; intelligence involves the use of tools distinct from the body. Instinct involves knowledge – an unlearned awareness – of living things. Intelligence, by contrast, involves the capacity to shape non-living matter.” Bergson116concludes that “there is no intelligence in which some traces of instinct are not to be discovered … that is not surrounded with a fringe of intelligence. The two are complementary and mutually antagonistic. In plants, consciousness and mobility lie dormant; the main features are vegetative “torpor” and instinct. Animals by contrast are endowed with greater consciousness and mobility.” Plant behavior is, in other words, largely instinctive (deterministic), although located beyond the fringe of instinctive responses there is a brain-in-waiting – the plant’s torpid behavior and its limited movement are indicative of a dormancy of consciousness: for Bergson,116 movement is always an indicator of consciousness, an idea rediscovered by Sheets-Johnstone.15 However, if intelligence “consists in an inflection of past experience” (i.e., memory), then it would seem that intelligence is fed by one of the aspects of consciousness, even though intelligence is not a necessary attribute of consciousness itself.

In relation to the structured scheme of consciousness (section 5) composed of 5 states of development, plants may, firstly, be said to be characterized by ‘torpor’ of their Sensorium (state 1); they do, nevertheless, also show a small degree of bodily mobility, which is the reactive, instinctive response to sensation. This latter attribute corresponds to the Bergsonian surrounding ‘fringe’ of brain-like activity (state 2). However, the property of mobility is one of degree. It is the nature of plants to be sessile, not mobile. Even though plants and animals share many fundamental genetic and biochemical properties, their respective body plans and modes of development differ, thus permitting only analogies, not absolute comparisons, to be made between plant and animal processes. Plants are of a class sui generis within the realm of living organisms. Secondly, brain-like activity in plants may be more developed than is generally thought. If this activity is supported by a phytoneural system (see section 13) capable of MT-derived OR events, then states 1 and 2 could be integrated and brought to a focus by some type of sensory binding within an emergent state 3, a state that may already be receiving impulses of protoconsciousness from OR events or, more directly, from a sensation of self, state 3[1,2]. It follows that the MTs of plants and their facilitation of OR events could serve as the bases for self-awareness, as proposed by Hameroff and Penrose1 for the human mind (state 3). And, as will be mentioned in section 11, quantum events that impinge upon neural activity may be responsible for occasions of ‘primary perception’ whereby 2 separate sensoria become aware of each other at a distance. These, too, might be brought to a focus within a mind at state 3.

With all these factors in view, we can now glimpse not only the circumstances under which plant ‘sensitive awareness’ exists and might contribute to the evolutionary conditions that develop and construct consciousness, but also how the Hameroff-Penrose Orch OR theory of consciousness might relate to this, especially when it is considered how much of plant development relies on MTs, the very items presumed crucial to OR events. However, the MTs that contribute to growth and development may be sites of other quantum events, such as quantum computations from which there is the possibility of initiating certain events deemed improbable as, for example, those described in the context of the development flower structure,118 and in relation to anomalous patterns of cell division.119

The central point of Orch OR theory

MTs have been found to be excellent electronic conductors, conduction taking various routes through the MTs, along their axes, and along and around their surfaces. The tubular structure itself promotes greater conductance than is possible through single tubulins; and conductance increases with MT length.1Importantly, MTs provide a vector for the electronic conduction. Orch OR theory proposes that MT quantum vibrations (in megahertz, MHz) interfere and produce much slower ‘beat frequencies’, and that these can be recorded by electroencephalography (EEG), a technique which records the collective pattern of neuronal activity in the brain and separates the pattern into bands (α, β, theta, …) of different frequencies. The mentioned beat frequencies are in the gamma range and are typically of 40 Hz frequency.40 The implication is that this 40 Hz gamma frequency is produced somewhere within the brain by its complement of neuronal MTs. Moreover, the beat frequencies, which apparently arise as a consequence of the disposition of tubulin as MTs, result in slower and, thus, more realistic, timescales for the repetitive OR events to be ordered as a conscious substratum than would be possible if the tubulin primary energetic vibrations of around 10 MHz were solely responsible for OR events. Thus, it seems that the organization of tubulin at specific sites into macromolecular MTs, such as occurs at the synaptic inputs1of animal neurons and the MT-organizing centers of plant cells (see later), assist in the orchestration of OR events as well as the generation of beat frequencies, such as those of 40Hz recorded by EEG.

There is one known post-translational modification of MTs – the acetylation of α-tubulin by acetyl-transferase120 – which may be important in this respect. It is thought that the acetylated sites of neighboring MTs are bridged by tau, a microtubule-associated protein (MAP), and that MT bundles are stabilized thereby.121,122 Tau is highly expressed in neocortical regions and the hippocampus, which suggests that tau has a role in neuronal activity, and that its presence in MTs underlies both fast and slow brain oscillations as well as long-range co-ordination of electrical signaling between the neocortex and hippocampus. Displacement of tau from brain MTs not only destabilizes the MTs and intracellular architecture but also impairs cognitive function, as evidenced from Alzheimer’s disease.123 Lack of tau protein also compromises neuronal functioning.124 Furthermore, it is probably significant that genetic knock-out of tau in Tau −/− mice brings about reduced levels of gamma synchrony involving the frontal cortex.125 The last-mentioned result suggests that bundles of MTs containing tau MAPs might be effective in promoting the beat frequencies at 40 Hz.

From the point of view of consciousness, the modulation of the gamma EEG frequency is of interest in another context. Buddhist monks during their meditational practice are able to self-induce high-amplitude gamma-band oscillations and phase-synchrony, particularly in the neocortical region of the brain,126 an effect not seen in novice meditators who had only a week’s training in meditational practice. These results concerning enhanced gamma frequencies were confirmed with a different group of experienced meditators.127 Moreover, a recent development in the study of gamma EEG has shown that, by applying an AC current with a frequency of 40 Hz to subjects during a period of REM sleep, an interval of ‘lucid’ dreaming could be interposed.128 In this state, the subject reportedly appears as an observer within his/her own dream, and is even able to intervene and comment on the action of the dream (ref. 129, p. 324). Stimulation with lesser (2 – 25 Hz) or greater (75 – 100 Hz) frequencies during the REM period failed to affect the content of the dream, which remained ‘non-lucid’. Together, these 2 sets of results suggest that the 40 Hz frequency is associated with elevating the Mind of state 3 into state 4 (Over-mind) whereby prolonged periods of self-observation would be possible. Interestingly, a flicker pattern of 50 Hz presented to the eye can be perceived subliminally by the human mind and is also able to induce moments of awareness.130

A further reason why the 40 Hz gamma frequency is of interest is that this frequency is believed by Hameroff and Penrose1 to be implicated in an OR event. The clue to this relationship lies in the equation τ ≈ ħ/EG, where EG is the gravitational self-energy, ħ is the Dirac-Planck constant, and τ approximates to the duration of successive OR events. EG may also be regarded as the mass difference between 2 states of tubulin in superposition; it is the superposition of the masses of these molecules in the form of quantum ‘bits’ which entangle, compute, and then collapse to thereby elicit an OR event.1,20,21

Evidently, if the value of one of the variables in the equation τ ≈ ħ/EG is known, the value of the other variable can be estimated. Thus, when τ has a value of 25 ms, as given by the 40 Hz gamma frequency, the estimated EG is equivalent to a mass difference occurring during superposition within a population of an estimated 2 × 1010 tubulin molecules. However, each cerebral neuron, instead of containing 2 × 1010tubulin molecules, is estimated to contain only about 109 such molecules, a tubulin mass which would result in τ = 500 ms (2 Hz). Moreover, it is presumed that only a fraction of these 109 molecules, when assembled into MTs, as well as being in superposition, would be directly involved in a coherent event of τ = 25 ms duration. Thus, in order to amplify the self-energy mass to the level necessary to elicit 40 Hz gamma synchrony, it follows that an aggregate of approx. 20,000 neurons would be required. It is then supposed that the frequency of such 25 ms OR events within the brain is such that they produce a continuous stream of protoconsciousness.

How do such estimates of tubulin mass and neuronal numbers apply to non-human animals and to plants? It is known that the nematode, Caenorhabditis elegans, has exactly 302 neurons.131 From the quantitative considerations above, it seems that MTs of the nematode organism would barely achieve the threshold energy-mass required for gamma-synchrony and, thus, are unlikely to be continuously conscious. Animals (and plants) with inherently fewer tubulin molecules may achieve conscious moments at a much reduced rate (due to the larger τ values associated with an OR event). In the case of C. elegans, τ would be estimated, on the basis of the data to hand, to have a value of 500ms.132 A similar rate may apply to plants, as evidenced by their spontaneous action potentials (see later). This would mean that protoconscious events are less frequent and, hence, consciousness is discontinuous.

Because it follows that, when EG has a smaller value and the value of τ is consequently increased, indicating a longer time between successive protoconscious events, different values of τ may be taken to represent a sliding scale, or grade, of consciousness. That is, larger values of τ would indicate a lower grade of consciousness, whereas smaller values would indicate a higher grade with more continuous spells of consciousness. A similar consideration applies to EG: its value, which is purportedly related to the density of MTs and their tubulin dimers within certain critical cells, would also bear some relation to the intensity of conscious experience. Given these considerations concerning τ and EG, it may be possible to set criteria for the grade of Orch OR-related consciousness in non-human organisms, including plants: these criteria would hinge upon the number and density of MTs.

There are a few qualifications regarding the Orch OR hypothesis which should be mentioned. Firstly, monks meditating may attain a ‘higher state’ of consciousness without displaying higher frequency EEG waves. Meditation may therefore act to enhance a prior-existing gamma-synchrony, perhaps achieved as a result of their previous, frequently repeated experiences of consciousness. Secondly, the Orch OR hypothesis treats the mass of tubulin as one continuous entity in the form of MTs. In reality, MTs in axons and dendrites in toto provide the requisite mass (EG in the Orch OR equation), and do so by means of fabricating, out of a labile pool of tubulin dimers, a higher-level structure – the microtubular bundles which arise due to the association of MTs with MAPs. The Orch OR hypothesis, therefore, may depend as much upon a critical number of linker molecules, such as tau, as it does upon the number of MTs. Thirdly, recent research has demonstrated that glial cells are required for EEG gamma synchrony (Lee et al., 2014),133 a discovery that again falls outside the Orch OR scenario. But it may be that glial cells simply provide trophic or metabolic support to the neurons with which they connect due to the proposed Global Molecular Network.80

Relevance of Buddhist psychology to the study of consciousness

Hameroff and Penrose1,134 showed interest in Buddhist writings on consciousness because these texts not only reveal the results of 2500 years of practical investigation of consciousness by means of intense meditation and contemplation135 but they also comment upon human cognition and human nature. These results help draw a map of human psychological structures. The same goal has been pursued by Hindu yogins, whose discoveries are recorded in the Vedas and Upanishads.136

The Buddha, Siddhārta Gautama (b. ca. 563 BCE), specified a number of causal phenomena (the 12 Nidānas) associated with the arising of consciousness. One of these relates to the sensations perceived through the eye, ear, nose, tongue, body and mind. There are also the 5 Skandhas (the active and reactive functions of consciousness) consisting of touch, feeling, perception, volition and awareness.135 These causal conditions flare up in the brain moment by moment, serving as triggers for moments of consciousness, but happening so quickly that the mind is barely aware of them. The Buddha also touched on ‘ignorance’, which represents evidence of a disconnectedness from consciousness (in the Buddhist sense) or, in terms of Orch OR, a disconnection from quantum protoconsciousness.; or, in terms of Rosenberg’s use of the term ‘protoconsciousness’,6 a dissociation between this property and cognition. The Buddhist practice of meditation is designed to pacify thought activities (thereby reaching state 3[1a−ᴗ1b-ᴗ2]) and to decrease ignorance, and thus produce perception of an unbroken sequence of conscious moments linking protoconscious events (the protoconsciousness of Rosenberg, mentioned immediately above) with consciousness via cognition. These moments prepare the Mind for entry into consciousness of state 4 (4[1a-ᴗ1b-ᴗ2ᴗ3]); here, it will be noticed, thought is not a requirements for consciousness.129Ultimately, one aim of this preparation is to connect the mind with the Universal Mind, leading to its blending with the ultimate oneness of the Universe at the transition from state 5 to state 6.

As recorded by Hameroff and Penrose,1,134 Buddhists see consciousness as “momentary collections of mental phenomena” and as “distinct, unconnected and impermanent moments,” occurring so rapidly that they seem to form a continuum. At the heart of this proposal is the Buddhist concept of ‘momentariness’.32As outlined by von Rospatt (ref. 32, pp. 21, 99), it is believed that there are 6,480,000 impermanent moments (Kṣaṇas) per day. Each moment would therefore be attributed a duration of 13.3 ms (≈75 Hz). Similarly, moments of 20 ms (i.e., 50 Hz) are proposed in some Chinese Buddhist texts. It is of significance that, as mentioned, EEG has recorded comparable frequencies of brain activity, and these have been correlated with a conscious state achieved by intense meditation.126,137 Hence, if we take the EEG 40 Hz gamma wave as an indicator of imminent quantum protoconscious events due to MT beat frequencies, then, as suggested by Orch OR, this would result in 3,456,000 moments of protoconsciousness in one day, each moment having a duration of 25 ms.

Another form of meditation, Zazen, practiced by adepts of Zen Buddhism, was one of the first to be studied by EEG.138 When the EEG outputs from Zen priests and disciples, who had varying degrees of meditative experience and proficiency, were compared, differences were found with respect to both their α and theta rhythms. As the ‘conscious’ state of the experienced meditators unfolded, the amplitude of their α rhythm increased while its frequency decreased (8–12 Hz falling to 7–8 Hz). At a later stage in the meditation period there was often the presence of a theta rhythm (6–7 Hz). These results were corroborated by Banquet137 and Murata et al. 139 and similar findings have been reviewed by Austin and others129,140,141Probably, gamma EEG rhythms were not technically accessible at the time of some of these Zen meditational studies. Although α rhythms were not mentioned in the study of Lutz et al.126 on gamma rhythms, it may be that, within the meditators who participated in this study, these comparatively low-frequency rhythms were replaced by higher-frequency theta rhythms and then by gamma rhythms as the meditation proceeded. Indeed, Banquet137 recorded EEG rhythms of 40Hz from meditators who had entered a deeper state of consciousness, using transcendental meditative techniques, and Murata et al.139reached a similar conclusion. An added possibility is that states of consciousness can be influenced by day-to-day variations of the Earth’s geomagnetic field, as suggested by the results of Persinger and others142-144 who showed that this field affects the results of EEG and the quality of meditation. It is also possible that the various Schumann resonance frequencies of 8, 14, and 20 Hz within the Earth’s ionosphere cavity145 may influence consciousness-related electrical activity within the brain, which itself generates similar frequencies, as recorded by EEG.

Coming now to a consideration of plants, Buddhists do not deny the possibility of plant consciousness. Indeed, the Buddhist view is that, there are (within the fifth Skandha of ‘awareness’, Vijñāna-skandha) 6 kinds of, or potentialities for, consciousness.135 On this basis, plants would be admitted to possess 5 of these attributes – of hearing, sight, smell, taste, and touch – but that they do not possess the sixth attribute of awareness, unless quantum computation, or some form of electrical activity, is considered as evidence of the sixth potentiality of consciousness, as will be elaborated when the idea of ‘oneness’ is discussed later. Nevertheless, the mentioned 5 attributes may be sufficient to qualify plants for protoconsciousness sensu Rosenberg.6

Moments of conscious awareness

The impermanent moments of protoconsciousness can be examined from another point of view. Entirely independently, and based on a study of time in relation to the Earth’s movements around the Sun, Gerhard Dorda2 estimated a quantal unit of Earthly time to have a duration of 49.6 ms (20.2 Hz). The threshold values for the uncertainty of the duration and for the ordering of these time quanta were estimated as 24.9 and 30 ms, respectively. The uncertainty associated with the duration of each time-quantum results in frequencies of temporal duration ranging from 13.4 Hz to 40.5 Hz. When expressed in ‘moments’ of temporal perception during a 24-h day, the quantal-time durations lead to an estimate of 1,157,760 such moments, with an upper limit of 3,499,200 moments per day. These values are of the same order of magnitude as the ‘moments’ of consciousness described in Buddhist texts,32 the last-mentioned value being close to the number of quantal protoconscious moments (3,456,000) that correlate with the 40 Hz gamma EEG frequency. Given the correspondence between the lower limit of the frequency of quantal moments of time (13.4 Hz) and the rhythms of α waves from EEG (8 − 12 Hz) during Zazen meditation, it is suggested that meditative states allow an ‘awareness of the flow of time’, one moment of meditative self-awareness (or protoconsciousness) corresponding to one unit of quantal time, and occurring sufficiently frequently for this ‘self-awareness’ to be perceived as a continuous process. The upper limit of quantal time frequency (40.5 Hz) is similar to the 40 Hz frequency associated with meditative state of mind.126

Thus, a succession of quantal moments of time, when processed during meditation, deposits an impression of continuous self-awareness or ‘moments of consciousness’. ‘Sensitive awareness’ of state 3 (Mind) is therefore a state in which the passage of time is sensed. This state corresponds to what Bergson116 called ‘duration’ (durée). He says, “Real duration is what we have always known as time, but time perceived as indivisible … I am aware that we normally … have no interest in listening to the uninterrupted humming of life’s depths. And yet, that is where real duration abides.” The state of “no interest,” which he mentions, is the usual characteristic of states 1 and 2 of Man. In state 3 and, more likely, in state 4, the “uninterrupted humming” of time (Bergson’s durée or duration) is perceived as an uninterrupted ‘moment’ of authentic self-consciousness. It is a defining feature of these 2 states. As Michael Foley (ref. 146, p. 27) remarks, although “Bergson offered no practical advice on how to experience real duration – attendance to the humming of the depths sounds remarkably like the Buddhist practice of Ānāpāna-sati, respiration-mindfulness,” i.e., the rhythmic breathing and self-sensing of meditative practice, which can lead to the deeper meditative state of Samadhi (ref. 135, p. 152).

How could awareness of the passage of time come about and bring about a continuity of moments that construct Bergson’s ‘duration’, or protoconsciousness? Dorda’s estimation of the duration of a quantal time unit is linked to the gravitational force experienced on Earth in conjunction with the gravitational effects of Sun and Moon.2 Hence, mass was also treated by Dorda in a quantum manner; indeed, Hameroff and Penrose1,20,21 also introduced gravity into their Orch OR equation and thereby derived an estimate of 25 ms for the duration of a moment of protoconsciousness, which is very similar in value to Dorda’s minimal estimate (24.9 ms) of a quantum of time.

Quantum units of both mass and time were considered by Dorda2 in relation to cellular growth in plants, a process dependent upon the movement of water into and out of cells. Cellular water was treated from the quantum perspective as providing quantal aggregates of mass. The temporal regulation of growth was hypothesized to involve quantum aggregates of water-mass being added to or subtracted from the main mass of cellular water during the passage of quantised time, this process being regulated by the orbits of Earth and Moon around the Sun. Recognition of the Moon’s orbit and the concomitant variation of the gravity field, in particular, accounted for rhythmic increases and decreases of cellular volume in the plant system (tree-stem dilatation growth) which Dorda2 took for his working example. In multicellular systems, synchronous rhythmic cellular growth becomes amplified and is seen as rhythmic organ growth. Such rhythms are, in turn, manifestations of a lunisolar ‘clock’, evidence for which has also been adduced from the diurnal movements of leaves and other plant systems where rhythms of cellular water movement are involved.147,148 Nevertheless, these rhythms of movement trace back to quantal time units and quantal aggregates of cellular water mass; and it is the succession of these events – passage of quantal time coupled with movements of quantal water mass – which we postulate to be the clue to human (and other animals) and plant examples of sensitive awareness at the state 3 of Mind (or, more exactly, of state 3[1a−ᴗ1bᴗ2], reducing here the state of awareness to that of the soma) – fundamentally, it is the sensitive awareness of Sensorium (particularly the quiescent sub-state 1a− as interpreted by the Brain, state 2) to the passage of time. How this rhythmic quantal movement of water-mass could be translated, in terms of cellular biophysics, into neural impulses is an intriguing question. Could it be that it works in a similar way to what was postulated for plants – that it is related to ventricular volume changes of the cerebrospinal fluid? The volume of this component in various regions of the brain has been estimated149 but diurnal variations have not yet been studied (C. Nicholson, personal communication). It is through this volume that a second type of signaling (volume transmission, VT) takes place, which contrasts with signaling due to ‘wiring transmission’ (WT) by neurons. Like the phytoneural transmission of plants and the hypothesized movement of water aggregates, VT depends on exocytotic vesicles,150 and these vesicles themselves may transport water aggregates. It should also be remarked that Dorda (ref. 2, p. 102) estimated that, with the passage of each unit of quantized time, an aggregate of 6313 molecules of water are either added to or subtracted from an intracellular water aggregate of approx. 1 × 1013 molecules at a frequency of 73 Hz (every 14.7 ms), this passage being regulated by the timing of the Moon’s orbit within the Earth-Sun complex.

Sensitivity to the passage of lunisolar time and gravity can be demonstrated by means of 3 examples of the activity patterns of a plant (bean leaf), a crustacean (crab), and a human recorded over long stretches of time in free-running conditions, where there was no contact with the external natural environment. Evident in Figures 1–3 is that, in each case, the temporal interfaces between 2 alternating periods – of movement and rest (crab) (Fig. 1), and of sleep and wakefulness (human, plant) (Fig. 2 and 3) – coincide with the times at which the lunisolar tide ‘turns’ (i.e., the lunisolar tidal force diminishes from a maximum high tide, or increases from a minimum low tide). This general pattern of a response to a turning point of the lunisolar tide is characteristic of many examples of both plant147 and animal (Barlow, unpublished) movements. The lunisolar gravity turning points correspond to times of day when the flow of water, either into or out of cells, is reversed.148 In all 3 examples of Figures 1–3, the turning points of lunar gravity have dramatic effects because they associate with abrupt changes of motor or growth activity of the experimental subjects. Nevertheless, it may be presumed that there is a constant subliminal awareness of this postulated inflow and outflow of water, and that a physical change in the direction of the flow, coincident with the lunisolar tidal change, corresponds with a change in biological activity. Each physical change, at the level of the cell, may be translated into a bioelectrical impulse. We propose that this sensation of the flow of time (duration), which may run in parallel with Orch OR events, is perceived as protoconsciousness of self during the integrated states 3 and 4 of Mind, when all other mental and physical preoccupations are quietened – at state 4 this would be notated 4[1a−ᴗ1b−ᴗ2ᴗ3] – by self-awareness and/or meditation.

‘Primary perception’ and its link with consciousness

In the study of Lutz et al.,126 EEG gamma synchrony appeared in the course of meditation which directed the mind toward “unconditional loving-kindness and compassion” and “unrestricted readiness and availability to help living beings.” In the terminology of religious prayer, this meditative state might be regarded as an intercessionary state: that is, a state directed toward some image or memory. Early results of Harris et al.154 showed that prayers directed from Christian intercessors were effective in shortening the recovery period of hospitalized patients suffering from disabling coronary conditions. Since that time, other, generally positive, responses from intercessionary prayers have been documented.155 Positive results have also been reported concerning prayer directed at injured non-human primates (bush babies).156 More controversial (because of a lack of follow-up experiments) have been reports of plants being injured as a consequence of negative or malicious intentions emanating from human minds, their moods and their feelings.68,157

Results of intercessory activity may give evidence of ‘primary perception’ in the recipients of such intercessions or directed intentions. However, it is unknown whether an explicitly religious context (e.g., invocation of a deity) is a necessary condition for a successful intervention into a disturbed state. A state 3 consciousness of Mind may be sufficient to impart an at-a-distance quantum entanglement linking the intention of the directed, intercessionary Mind (of the healer) with the body and mind of the recipient (the one to be healed). Entanglements that resolve a bodily healing (or harming) process within the soma (sub-state 1a) of the recipient may be the means by which primary perception takes place, and could also be the route taken for healing through shamanic practice.158

Prayers for altered interpersonal relationships may be another area where state 3 consciousness of the intercessor can effect an emotional or psychological response.159 But in this case, where, for example, forgiveness of one party (the violator) by another (the violated) is prayed for by the latter party (who is also the intercessor), it is more likely that the reconciliation occurs by primary perception at the level of emotional self-awareness (sub-state 1b) and would pertain to the intercessor (the violated) him/herself. Whether intercessionary transfers by entanglements of consciousness would be more successful if gamma-synchronized, self-conscious state-4-embodied Minds were involved is an interesting question.

The above examples referred to perception at-a-distance. However, with regard to plants,68,157 the described cases of primary perception were ‘at-close-quarters’. Here another possibility presents itself: that of Mind as a force-field.160 A possible effector of this mode of perception is the electromagnetic field generated by the vast assembly of electrically conducting neurons of the brain. As pointed out by Nagel,24who reviewed a number of relevant publications, plants are susceptible to intercessory prayers, or ‘friendly thoughts’. She suggests that “prayer can be considered a form of mind power,” in the sense discussed by Lindahl and Århem,160 although she does not mention this particular publication. She also comments that “if ‘primary perception’ did exist in plants, this would not necessarily prove that plants are conscious.” The results of prayer would simply be evidence of a susceptibility of some sort toward the mind that formed the prayer. However, for susceptibility of either plant or animal to be recognized by an observer, there would be the need for its translation into an observable movement (growth) and/or physiological change. A directed meditational technique (‘thought transaction’) invoking “wellness of the crop and good yield” was reported to bring about an enhancement of okra (Abelmoschus esculentus) plant growth161 and resistance to nematode infection. The transaction involved the preparation of a mental state at which theta frequency (4 – 8 Hz) EEG waves became manifest. It was maintained, in the presence of the plants, for 5 min each day for 60 d. At harvest, okra crop yield, in kg, of the ‘thought transaction’ group of plants was enhanced by approx. 20% compared to ‘non-transacted’ controls.

Even more intriguing are the observations of JC Bose162 who recorded minute changes in the growth of wheat coleoptiles (using a ‘crescograph’ of his own invention, which magnified growth by × 50 × 106) each time a controlled electrical discharge took place. The discharges took place at a location 200m distant from the test plants. Discharges were fed to a transmitting aerial and were recorded by the plants, which were linked to a receiving aerial. The claimed ‘wireless’ communication indicated that plants could theoretically “respond to the long æther waves, including those employed in signaling through space.”162Bose was careful to distinguish between the internal and external effects of these wireless waves on the receiving plant, the former effects manifesting as growth movements whereas the latter had no such outward manifestation but consisted of, so Bose believed, a chemical change with a concomitant increase of potential energy.

The occupancy of Mind at state 3 may be a means by which humans can ‘communicate’ with plants, and vice versa. It may also play a part in inter-plant communication as, for example, in phenomena such as kin recognition,163-166 one of topics which has also been central to discussion of plant cognition.29 Kin recognition may trace to the consciousness criterion no. 12, ‘subjectivity’, where kinship is the source of a sensation private to a given plant. It, too, may be a situation whereby quantum or electromagnetic effects achieve communication over long- or short-range distances, with observable consequences. Primary perception may also be the means by which animals communicate and show their concern for one another, and how plants communicate warning signals to each other, though this latter may also involve volatile chemical signals.167 Such examples seem to be forms of sensitive awareness of one being toward another that transcend mere instinctive responses.

The idea of plant ‘oneness’

Plants, by virtue of their open and branched pattern of primary growth, are continually emitting new parts and, hence, fragmenting their individuality, particularly when engaged in vegetative reproduction – by emitting suckers, for example, which eventually assume their own individuality. Branching occurs not only externally by budding but sometimes also internally, by splitting (schizogeny) of tissues as well as of organs. Organ splitting affects the form of trees when, for example, an aged trunk splits and forms second-order trunks. In this way, multiple copies of new individuals (clones) are formed, which eventually supplant the original first-order trunk. Nevertheless, in plants, there may be a contrary striving: for integration, or ‘oneness’, to compensate for this branching of organs and the tendency to fragment. The fusion of aerial roots, typical of some trees (those Ficus spp, for example, whose intertwined roots form an aerial pseudo-trunk), may be an expression of such a tendency toward oneness, and which follows on from an earlier phase of root and shoot branching. The gathering together of parts that were once separate is similar to what occurs in swarming or flocking events among insects and birds.168

It is as though, by means of an internal act of primary perception, the plant or tree has a sense (or consciousness overseen by a Mind at state 3), not only of its parts, but also of its form; and through this self-awareness of form arises the means whereby a plant’s own oneness can be attained. An aspect of this tendency toward oneness derives from the property of whole-plant ‘correlation’.169-171 It is the means by which not only the fundamental architectural form (or model) of the whole is realized during undisturbed development172 but also is regained after partial dismemberment. In each case, information is communicated within and between the various entities at their respective organizational levels. However, the correlative process also operates internally, and also at more restricted levels, within organs and tissues, enabling the maintenance of their respective integrities.173 The necessary communicative processes are due, in part, to the movement of plant growth regulators – auxin, for example, which has neurotransmitter-like properties, and is probably also assisted, or mediated, by MTs and the cytostructural code. Presumably, in order to re-establish the correct architecture (after an injury, say) the plant titrates the entire system for hormonal composition and quantities, as well as making use of the bioelectrical code,67 part of which involves electropotential difference (EPDs) between growing parts. These procedures re-establish the balance of the various morphogenetic components until equilibrium is reached in the meristems and their immediate derivatives: that is, there is a restoration of the optimum sense of ‘oneness’.

A second aspect of ‘oneness’ is that plants are only partially compartmentalized into cells and organs; the totality of their cells in fact forms one continuous, cytoplasmic network.174-176 This intercommunicating, symplasmic system has few if any insuperable barriers to an internal ‘oneness’.

Another aspect of ‘oneness’, and one which includes the plant’s discovery of its sense of ‘sameness’ as well as its sense of ‘otherness’, may arise, not from the plant’s interior but from the organisms which surround it. This could be through inter-organ primary perception, or by means of communication mediated by electrical fields and possible quantum entanglements, as well as by chemical means – elements of a type of ‘kin recognition’, but a type that operates at the level of the organism and, again, utilizing the cytostructural and bioelectrical codes. This possibility, that use is made of internally generated bioelectromagnetic properties, has many ramifications in relation to plant communities of small size, and has been suggested as a means facilitating seed germination and seedling growth.177,178 It is anticipated that other unknown but mutually influential factors may also operate between plants.164 If so, then plants may be able to direct their own ecologies through plant-plant interactions more subtle than those due to either allelopathy via secreted chemicals or restrictions on living space brought about by nutritional preferences.

Do plants have a nervous system?

Nervous systems in many ‘higher’ animals are characterized by specialized cells which propagate action potentials (APs) as a consequence of membrane depolarization and the movement of ions into and out of neurons. Such systems involve electrical synapses (gap junctions) and chemical synapses facilitated by neurotransmitter substances. There are approx. 60 types of neurotransmitter molecules in humans, including acetylcholine, amino acids, and biogenic amines; MTs support and guide the vesicles in which these molecules are contained toward the inter-neuronal synaptic junctions.

Action potentials in plants were first recorded in a higher plant (Mimosa)179 and in a green alga (Nitella),180 long before their discovery in animals. If algae and higher plants have a ‘phytoneural’ system which is similar to any of the various animal nervous systems, then not only should APs be expected, but plant anatomy might also reveal cellular structures and ultrastructures (such as exocytotic vesicles and MTs), as well as specific molecules which have been adapted to participate in the development of APs at cell boundaries. It is believed that plants do indeed possess ‘plant chemical synapses’, and that these share many of the features of chemical synapses found in animals.181 As for the identity of the phytoneural cells in higher plants, anatomical and physiological evidence indicates that they correspond to the phloem strands, and that these strands propagate APs over long distances,72,182,183 as also occurs within the giant cells of green algae. Also, numerous molecules have been discovered in plants36,184 – for example, gamma-aminobutyric acid (GABA), melatonin, serotonin – which, in animals, serve as neurotransmitters. One of the roles of these molecules in plant cells is to modulate MT stability;59 and it because of this property that they affect neurotransmission in animals.185 Certain other molecules found in plants can also modulate animal neurotransmission – for example, hyperforin, which increases acetylcholine release from cerebral tissue,186 and some secondary plant products are potent animal neurotoxins and hallucinogens – nicotine, curare and psilocybin, for example,187 all of which affect the acetylcholine receptors and the passage of electrical currents via chemical synapses. Inhibition of these last-mentioned receptors is also a feature of certain anesthetics.188,189 Thus, plants do indeed possess structural and chemical elements which could participate in a putative phytoneural system, though at present there are no details of how they do so.

Plants, because they are encased in cellulosic walls, are typically sessile organisms. Their physical movements are measured in days rather than in seconds, as would apply to animals. If plants possess an analog of the animal-type nervous system, it may either function slowly – to alter the orientation of an organ by differential growth, or more rapidly – by activating molecular transport mechanisms which can then lead to an alteration of physiological state. The nervous reactions involved initiate an immediate electrical response, ion exchange being followed by cascades of other signals; the latter then propagate relatively slowly throughout the organism. The animal nervous system which perhaps most closely resembles that of a plant is the one expressed in sponges,190 where GABA is used as neurotransmitter.191Sponges belong to a basal phylum of the Animalia and possess ‘protosynapses’;74 these seem to be similar in function and structure to the plant chemical synapses proposed by Baluška et al.181

The different nervous systems found in sponges, animals and, putatively, plants, indicate that nervous systems have probably evolved many times during evolution, as was also proposed for brains73 and, indeed, was also proposed for consciousness itself.12 What critics of the notion of plant neurobiology have overlooked (due, probably, to an anthropomorphic orientation) is the diversity of nervous systems and neurons within the animal kingdom. Furthermore, Edelman et al.12 draw attention to the finding that the octopus (which these authors credit with both cognition and a precursor of consciousness) has more neurons in all its tentacles than it has in its brain, suggesting that some attributes of ‘consciousness’ might reside elsewhere than within a brain. As Moroz73 remarks in responding to his own question “What is a neuron?,” it is that they “can make polarized and specialized (synapses) connections, but do not necessarily do so in all animals and nervous circuits.” Moroz74 continues, “Hormonal-like volume transmission [see earlier] can serve many true integrative and neuronal functions without a specialized synapse … if targets are localized within a few micrometers from the transmitter release points.” The author is referring here to nervous systems which are used by “sessile animals with limited motor reactions or for vegetative processes.” Such a description for certain animal nervous systems corresponds with the situation in plants. The mention of volume transmission suggests that plants, too, may have a ‘Global Molecular Network’,80which could be constituted of both a WT system (bioelectrical circuitry) and a VT system (phytohormonal and growth regulator mobility, including microRNAs), which together would help sustain the global inter-cellular and inter-organ communication system needed to maintain a plant’s sense of ‘oneness’ (see the preceding section). Thus, no special pleading is needed for a ‘phytoneural system’. What has been discovered so far is that its features lie within the range of diversity of neural systems in toto.

One specialized site on the cell membrane of animals across which an electrical current can flow is the gap junction. These may be important in regulating bioelectric fields, which, in turn, appear to regulate the correct spatial distribution of cellular groups in embryos and elsewhere in the soma.192 Possible plant analogs of the gap junctions of animal cell membranes are the cell-cell channels known as plasmodesmata.193,194 These structures are inserted, in the first instance, into new cell division walls. Secondary plasmodesmata are sometimes inserted at a later time into particular pre-existing cell walls of differentiated tissues.195 These secondary plasmodesmata may be analogs of the recently discovered tunneling nanotubes which link cells together via adventitious cytoplasmic bridges.175,195 Plant parenchyma cells have the ability to propagate electrical impulses through the plasmodesmata and, hence, through the symplasm until they reach non-excitable neighboring cells.196,197 However, the current so propagated is strongly damped due to a bottleneck effect exerted by the plasmodesmata themselves, thus limiting the range of the electrical signals to only a few cells.196 This result was obtained from root apical meristems of the fern, Azolla pinnata, in which plasmodesmatal abundance, densities, and cell-cell distributions have been carefully mapped. Even in giant shoot apical meristems, such as those of the Cactaceae, which have possibly tens of thousands of cells, the scale of coherent electrical signaling would be limited to a small number of cells at any one time. It follows that, in both shoot and root apices, Orch OR events and the subsequent propagation of bioelectrical impulses would occur only slowly and possibly infrequently.

Orch OR suggests that EEG gamma synchrony occurs by means of the coordinated activities of MTs, synapses and gap junctions.198 Halothane and ethylene, anesthetics which work as such on animals, destabilize MTs in growing plant cells199 although, unfortunately, little is known of any putative phytoneurological effects of anesthetics save their ability to alter the sensitivity of plant cells to cold stress,200 an effect probably mediated by MTs. Interestingly, ethylene brings about the rearrangement of MTs in growing cells of dicotyledonous plants, thus enhancing the lateral expansion of the respective plant organs.201,202 The newly formed growing portions of an ethylene-treated shoot or root therefore remain squat, as though ‘resting’ and waiting for conditions to ameliorate before resuming rectilinear growth. Because ethylene is released from plant organs following wounding, this ‘resting’ response may be some form of self-anesthesia.

Does Orch OR apply to plants and, if so, could plants be conscious?

The Orch OR hypothesis, with its reliance upon MTs to facilitate the firing of electrical nervous impulses, has many favorable points for an understanding of the origin of human consciousness and, as has been described in earlier sections, recent experimental results have provided circumstantial evidence for its applicability to consciousness processes. In animals, MT arrays are crucial for electrical signaling within and between neurons whereas, in plants, the corresponding electrical properties and their role in intercellular signaling are imperfectly known. Although Baars and Edelman47 were doubtful that MTs, whether in animal or plant cells, could be a sufficient basis for ‘quantum consciousness,’ the Hameroff-Penrose Orch OR hypothesis does nevertheless suggest that quantum OR events provide a potentiality for moments of protoconsciousness. It should follow that all such moments are liberated by OR events, and that their frequency would depend on the number and density of MTs. On the grounds of this last-mentioned prediction, plants, which have no particular type of cells that are directly equivalent animal neurons in terms of their degree of enrichment with MTs, might in this respect be disadvantaged in their attainment of consciousness.

Actin microfilaments which, in addition to MTs, are the other major class of structures of the plant cytoskeleton, should also be considered with respect to their electrical capabilities. In a recent study where a 50Hz oscillating electrical field was imposed on plant tissue, permeabilization of the tissue was brought about in a manner dependent upon the presence of actin, suggesting that actin filament oscillation and/or cytoplasmic streaming may be allow the opening of the plasma membrane,203 which possibly may allow the initiation of APs.

In the preceding section, primary meristems were considered to be rather poor candidates for OR events on account of the lability of their MT population, and then the short cell-to-cell distances over which electrical impulses could be transmitted via plasmodesmata, to promote moments of protoconsciousness in some brain-like center. The situation is different in tree trunks, however, where there is a secondary cambial meristem from which secondary, or widening, growth is established. Cambial cells are not only extremely numerous, covering the entire cylindrical surface immediately beneath the bark, but they and their derivatives are also replete with MTs which participate in the development of both woody tissue204 and secondary phloem. The MTs of these cells have more stable configurations than those of meristems. There are also groups of parenchymatous ray cells, which intrude into secondary phloem and secondary xylem (Fig. 4A) and which are rich in MTs. Unlike the immediate derivative cells of primary meristems, derivatives of ray cells remain for a long time close to their site of origin, do not divide, and live for at least 4–5 years. MTs of ray cells appear bound together as microtubular cables205 (Fig. 4B). Ray cells also contain prominent cables of actin filaments (Fig. 4C and D). Additionally, there are abundant, closely bound helices of MTs lying against the plasma membrane of developing secondary xylem cells, as well as circles of MTs at the pit borders of xylem vessels.206 Similar findings apply to the secondary cambium and vascular tissues of woody root systems.207 The numbers of MTs in such cells and tissues has not been estimated, but considering the total volume of tissue present in a mature tree, these numbers would be prodigious. However, an approximate number of MTs can be reckoned, as shown below.

Ray parenchyma cells within secondary stem tissue of trees. (A) Vertical columns of rays (spindle-shaped groups of small cells) located amongst elongated fusiform cells within the stem cambium of a two-year old hybrid poplar tree. Toluidine blue-stained …

Ray parenchyma tissue is composed of up to 8–16 or more tiers of cells (Fig. 4A). Tangential cuts through the cambium also reveal that the ray complexes are organized in a helical pattern along prominent parastichies winding around the cylindrical cambial surface. Thus the secondary xylem and phloem tissues beneath the bark of a tree trunk have embedded within them a lattice of radially intrusive rays (Fig. 5). Because most of the ray cells no longer divide and their differentiation is rapidly completed, their MTs would be available for new functions and might provide the conditions for Orch OR events. Moreover, all ray complexes traverse the cambium and could thus feed signals transmitted radially, by the rays, into the longitudinally oriented cambial system which extends into the apical and basal extremities of a tree. The density of ray clusters shown in Fig. 5 is estimated as approx. 70 per mm2, a value which might offer possibilities for amplification of MT-based OR events, particularly since the lattice configuration of the rays might itself provide a basis for the mentioned amplification by introducing an extra dimension for the postulated quantum computing required by Orch OR. The large total number of MTs collected into such a lattice encircling the trunk of a large tree could therefore be a powerful structure, analogous to a population of MT-bearing neurons within a brain, for the triggering OR events. Hence, ray tissue could be a location for propagating moments of protoconsciousness. In this way – through MT density and large number of ray cells within a lattice arrangement, where quantum computing and quantum entanglement could take place – the potential limitation would be overcome of not having one particular cell type, like a neuron, or tissue especially enriched by MTs, like a brain. The entire trunk of a tree filled with rays and their MTs could be regarded as a candidate plant brain (on a large scale), where protoconscious events might be produced by Orch OR.

Distribution of rays, such as shown in Fig. 4A, recorded in a large photomontage of tangential sections of hybrid poplar cambium. The montage was scanned and the vertical height was foreshortened. The spindle-shaped ray areas were then traced (stippled …

MT-bearing rays embedded within tree trunks with their potentiality for OR events may be the reason, at a subliminal level, why sensitive persons wish to ‘hug a tree’: it is an indication of the resonance, or quantum entanglement-at-a-distance,45 of tree and human MT-beat frequencies emanating from both the human neuronal and the putative ‘phytoneuronal’ channels of the ray system, perhaps coupled also to bioelectromagnetic field effects between the tree and the human brain and heart. The dual tree ray-human MT system could be another situation for primary perception, and thus be the site of something similar to kin recognition mentioned earlier. Although it is not known whether the gamma synchrony of the type recorded by EEG from human subjects, and which is associated with consciousness, is present in plants, the cambium and its ray and secondary tissues of trees may be a good place to start to search for such synchrony.

Quantitative estimates of tubulin and MT characteristics in the trunks of young trees of hybrid poplar clarify the potentiality of rays for generating Orch OR events leading to moments of “tree protoconsciousness.” Data on ray density were obtained from images, such as shown in Figure 5, and additional quantitative values for the volumes of ray tissue in secondary xylem and phloem are taken from Barlow et al.208 The estimates are as follows:

Figure 5, which is typical of a poplar tree trunk seen in tangential section through the cambial zone, reveals that there are 85 ray complexes inserted within a cambial surface of 1.2 × 106 μm2.

Single, uniseriate ray complexes are approx. 250 μm high (in the vertical dimension), 14 μm wide and, in one annual growth ring of xylem and phloem, approx. 4610 μm long (in the radial dimension). Rays complexes of poplar are viable for about 4 years;209 in the fifth year following their birth, the cells die. All told, therefore, the volume of one typical complete living ray complex is approx. 6.5 × 107 μm3.

A microtubule of length 1 μm consists of 1600 tubulin dimers.210 Therefore, a single MT, 4610 μm long (i.e., the total length of one typical living ray complex), consists of 7.4 × 106 dimers. A conservative estimate that 100 MTs extend the length of such a ray complex yields a total of 7.4 × 108 dimers.

Ray complexes are multicellular, composed of one vertical file of approx. 8 cells. Files of each of these 8 cells extends in the radial direction. Hence, there would be approx. 5.9 × 109 tubulin dimers in the set of 8 radial files of one typical single ray complex.

Hameroff and Penrose state that a single cerebral neuron contains approx. 109 tubulin dimers. In terms of tubulin mass, one complete ray complex is equivalent to a single neuron.

According to the Orch OR hypothesis, a quantum superposition of duration τ ≈500 ms requires 109tubulin dimers. Thus, a single, 3-dimensional ray complex may be able to supply the necessary tubulin mass for an OR event at intervals of 500 ms (2 Hz). Many ray complexes working together in their lattice arrangement may increase this frequency.

One proviso with respect to the ray system is that in order for the ray MTs to behave analogously to a single animal neuron with 109 tubulins, continuity of MTs should be maintained throughout all the cells of the ray complex, both vertically and radially. MAPs such as tau associated with MTs, as well as plasmodesmata which support the cellular symplasm, may provide the necessary degree of quantum coherence.

If such a system were capable of orchestrating OR events in the way proposed by Hameroff and Penrose,1then there is the question of how the resulting moments of protoconsciousness would be registered in the ‘mind’ of the tree. Of course, this is also a problem for bona fide systems of animal consciousness. Furthermore, one might ask whether the stream of sensory inputs to the plant from both internal and external sources can be integrated by means of Orch OR. Thus, for a plant or tree, there may also be the ‘binding problem’ of how to establish a unification of conscious perception.35,37 But this might not be such a vital problem for a tree, as it is for animal/human systems, where it is essential for their survival, for example. And, as was mentioned earlier, thought (as supported by a brain) is not a necessary component of consciousness.

Alternative modes of consciousness

Because there are different types of brains and nervous systems among animals, as well as different modes of consciousness,13 the approach to the question of whether plants can be considered ‘conscious’ may be made only in an analogical way using animal systems as a reference. However, the way becomes clearer when consistent attributes of consciousness are recognized – albeit using attributes derived from studies of animals, both human and non-human. Earlier, a structured series of conscious states was provided, and it was deduced that, in the human situation, and also in the light of Hameroff and Penrose’s Orch OR theory of protoconsciousness,1 whenever neuronal vibrations of lower frequency were, even if momentarily, replaced by vibrations of a higher frequency (theta and α frequencies of 4–7 Hz and 8–15 H, respectively), and thence to gamma frequencies (of 40–100Hz, for example), there may literally be a ‘quantum’ leap into a deeper level of reflective-, or self-, consciousness. This might be due to OR events in the Brain apparatus (state 2) somehow becoming registered within a Mind (states 3 and 4). For plants, the corresponding situation, especially the final step of registering consciousness, is nearly unknown, but some clues regarding the preceding steps can come from studies of action potentials (APs) as indicators of electrical activity.211 Quantum effects at ion channels have been proposed to induce APs,19 and the electromagnetic field generated by the multiple APs of cerebral neurons has been advanced as a component of conscious awareness.212 Action potentials and their relevance to possible plant consciousness will now be explored further.

Interior protoconsciousness: An electrical basis

In plants, besides the presence of electropotential differences (EPDs) across organs, there is continual transmission of electrical action potentials (APs) via vascular tissues. For example, whenever sap flows within living phloem cells,213 or whenever there are changes in hydrostatic pressure within xylem vessels,214 there is excitation of membranes which then generates APs and sets up EPDs between reference sites along the organs concerned. Moreover, the arrival of APs at certain destinations, or target zones, is likely to promote distinct patterns of gene activity,215,216 as well as cascades of secondary messengers, such as Ca+ ions, and the stimulation of phytohormonal transport, and thence lead to various motor activities. Actin microfilaments and actin cables within ray cells (Fig. 4C and D) and elsewhere may also convey sufficient kinetic energy to disturb cell plasma membranes and induce APs.

Internally, plants are rarely quiet, except at night and under relatively still conditions.213 Environmental stimuli – light, temperature, salinity, drought, waterlogging, contact with predators, gaseous signals released from sites of infection in neighboring plants, even the passage of clouds across the sky – can all modulate phytoelectrical activity. Because of the incessant input of signals from the environment, as well as the widespread internal signaling between organs and modules, plant systems are ‘alive’ with electrical activity. Thus, in addition to local brain-like areas (root apex transition zones, e.g.,), the whole plant, and especially the trunks of trees, can be viewed as a distributed ‘brain’, in the sense of ‘brain’ being a center for the integration of electrical activity. This distributedness contrasts with the situation in higher animals (but may correspond to the already mentioned situation in sponges) where electrical signaling is channeled toward a localized and integrating central nervous system and brain. Then, the phytohormonal correlative system, which is able to initiate appropriate morphogenetic responses to impulses originating from a diffuse ‘brain’ or some other localized command center75,76 and thereby regulate the structural form of the organism, provides the plant with a sense of self, or of ‘oneness’ (state 3). This may be the nearest we can come to resolving the question of whether (or not) plants are conscious, with an awareness of self and of others.

One further aspect of plant electrical activity should also be mentioned. This continual activity, due to the plants’ continual responsiveness to their environments, masks another, more basic aspect of phytoelectrical activity inherent to the structure of plants. Such an intrinsic and basal electrical state should be discoverable when the environment is totally stable. Then, quantum reduction events, perhaps due to MTs, or events due to actin filament kinetics, should become apparent. Hence, it is of interest to estimate the frequency (in Hz) of APs during resting periods, when plants are free from perturbation. A survey of APs recorded from base-line, unstimulated states approximating to ‘free-running’ conditions allows the following estimates of their resting frequencies to be made.

The simplest case in this survey is the trichome of the blue-green alga, Phormidium. These cells show no electrical activity (0 Hz) except when they are transferred from light to darkness; then an impulse is recorded, coincident with the transfer.217 From the giant unicellular green alga, Acetabularia, spontaneous APs with frequencies of 8 × 10−4 Hz and approx 2.3 × 10−3 Hz were recorded from cells in a quiescent state by Thavarungkul et al. and by Saddler, respectively.218,219 At the developmental stages studied, MTs would have been either absent or sparse.220 Similarly, APs of 3 × 10−2 Hz were recorded from the giant cells of the green alga, Nitella mucronata.180

In non-vascular and vascular plants, spontaneous APs, sometimes in long trains of activity, arise without any known cause. Records from thalli of the liverwort, Conocephalum conicum, showed electrical discharges with frequencies of 2–3 × 10−3 Hz.221 Although these signals were recorded sometime after a wounding event, they had settled to a constant frequency and amplitude and the tissue appeared to have recovered from the trauma when these estimates were made. From growing stems of Helianthus annus, spontaneous impulses with frequencies of 1 × 10−2 Hz were consistently found;222 and from growing portions of stems of Dianthus sp. (where cytoskeletal MTs and actin filaments would be abundant) spontaneous APs with frequencies of 0.2–0.25 Hz were recorded by Glębicki et al.223 However, a frequency of only 0.08 Hz was found in the non-growing, basal zone of the stem, where the cytoskeleton might be expected to be less developed. From various zones of a small tree of Ficus elastica, the highest electrical impulse rate, recorded during a period of many weeks, was 3.3 Hz.224 Unfortunately, the exact locations of the recording zones were not specified and, moreover, the frequencies varied from minute to minute: one zone had a frequency of 0.8 Hz, another of 1.7 Hz, while a third zone showed 1.7 Hz one minute and then 0.3 Hz during the next minute. Nevertheless, the impulses were a constant, unprovoked feature of recordings from the whole tree. Pickard225 studied APs from petioles and lamina of cotyledons of Ipomoea hederacea. Successions of spontaneous electrical impulses were found, often persisting over long periods of time, the longest period recorded lasting 44 min; the average frequency of these impulses was 0.95 Hz. Williams and Pickard226 recorded impulses of approx. 0.12 Hz frequency from tentacles of Drosera intermedia, when the material was apparently in a stable, free-running condition. It is interesting that in both the study of Karlsson224 and Zawadski et al. 222 diurnal rhythms of the impulses were noted, but these were probably related to the daily changes from light to dark conditions. Nevertheless, they indicate that plants can be aware of the time of day through the frequency and amplitude of their APs.

From roots of Lepidium sativum, Hejnowicz et al.227 registered electrical signals of 2–5 Hz during the first minute of one typical recording session, and which diminished to 0.3 Hz in the next minute. The most coherent signals were found in the apical meristem and just behind it, where the transition zone would be located and where the cytoskeletal MTs would be densest. According to the authors, gravistimulation of the root did not affect the fluctuations of the APs “in any reproducible way.” However, exposure of the roots to both N2 gas (anoxia) and ether vapor reduced the frequency of the impulses. The effect was reversed by flushing the gases from the system with clean air. Both these gaseous agents disassemble MTs in a reversible way.228

Notable is that all AP frequencies were relatively low. Furthermore, APs in plants have relatively long refractory periods; and if multiple impulses were to arrive from different locations, this would tend to confuse any evaluation of an average frequency at the recording site. Nevertheless, the consistency with which a low level of electrical activity is encountered in non-stimulated plants is probably significant. It suggests a degree of torpor, or baseline sensitive awareness; nevertheless, the plant can be aroused from this state when appropriate stimuli are provided.

Other types of electrical signal214 are more frequent when plants are appropriately stimulated – by wind action, for example, which is able to induce volume potentials due to hydrostatic variations;229 and EPDs become evident when trees photosynthesise, transpire, and translocate sugar solutes.213 Thus, there may be 2 periods of protoconsciousness for trees and plants: one during rest within the hours of darkness, the other during wakefulness and consequent upon environmental stimuli, which are more abundant during hours of daylight. Activity patterns in the form of EPDs are also modulated by lunar phase230,231 in the same way that activity patterns of animals are affected (see Fig. 1 and 2).

Exterior protoconsciousness

One topic not discussed by Hameroff and Penrose, believing it to be outside the scope of science, is the possibility that protoconsciousness might occur in non-biological systems, including the cosmos itself.1,45This they did not discuss. However, as JBS Haldane wrote, “I have no doubt that in reality the future will be vastly more surprising than anything I can imagine … my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.” Thus, it can be surmised that whatever topic has been considered outside the scope of science in one era (e.g., theories of planetary motion and of gravity, wave-particle duality, dark matter) might enter the scope of science in a succeeding era. Therefore, one might touch on this unknown issue of a non-biological origin of protoconsciousness,1,45 partly because Hameroff and Penrose entitle their article, “Consciousness in the Universe” and then continue (see their abstract) “we conclude that consciousness plays an intrinsic role in the universe” (our emphasis). While one may puzzle about what this “intrinsic role” may be, protoconsciousness can be imagined to exist independently of a biological context (as indeed Hameroff and Penrose speculated,1 but then in the context of massive neutron stars), and that it is an imminent property within the Universe due to physical laws; it is as though scintilla of protoconscious could theoretically exist and await capture by biological organisms who have the ability (or wish) to perceive them. For example, the Schumann resonance frequencies145within the Earth’s ionosphere correspond with frequencies recorded from the brain by EEG, but whether the Schumann frequencies intervene in such electrical activity and, hence, in consciousness, is not known.

Three vital questions surround the OR event associated with consciousness in living forms: 1) Is a protoconscious event generated only by MTs? 2) Can it be that certain groups of MTs within a biological organism attract to themselves a precursor (scintilla) of protoconsciousness from a universal pool of such events which reside in the cosmos, and then relays and amplifies it to consciousness via the neurons? 3) Are biological/quantum-physical protoconscious events simulations of analogous events within the cosmos?

As mentioned in section 10, a perception of self and an awakening of activity in the soma emerge at the turning of high and low lunar tides (Fig. 2). This awareness, this subliminal consciousness of self, is thus the consequence of the soma and brain being touched by an interaction with the cosmos – the relationship between the organism and the gravitational attraction between Earth, Moon and Sun. In this regard, where Organism-Earth-Moon-Sun forms a unit, a fully developed, continuous awareness of organismal self might be considered to be an answer to a further, fourth question: Can consciousness in a living organism arise from some physical feature of the cosmos?

At present, however, the quantum-physical protoconscious events of Orch OR can be usefully discussed only at the human/biological level, mainly because discussions of consciousness center upon human consciousness. But a more general, or even a more universal, aspect is suggested by questions 2 and 3 above. The topics to which these 2 questions relate can be analogized to the perception of Cherenkov radiation by astronauts.232,233 When astronauts of both the Apollo and Soyuz missions were in darkness or with eyes closed, and especially when they were in a relaxed state, they experienced flashes of light, at the intra-ocular location where vision would be normally experienced. One explanation is that radiation (probably muons and pions) from outer space penetrated the space capsule, and traveled through the astronaut’s eyeball and interacted with the retina, triggering an event registered in the brain as a flash, or streak, of light. Continuing from this example, so it may be with moments of protoconsciousness: perhaps neurons of the human brain are from time to time penetrated by precursors of protoconsciousness as a result of which sensitive sites, say among the arrays of MTs, are caused to activate a neural mechanism, the transduction of which is a ‘flash’ of consciousness. Furthermore, and in keeping with this speculative view of the induction of consciousness, the duration of the Cherenkov flash within the eye is short (≤ 10−10s) compared with the integration time of the eye (approx. 50 ms).232 Similarly with quantum protoconscious moments: an OR event occurs within a moment of time lasting about 13–20 ms; longer times (25 and 30 ms) are required to bring about, respectively, the recognition of the event and to set it in the correct place within the sequence of such events.Concluding remarks

The evolution of animals and plants has allowed each to develop a Sensorium (state 1) and a Brain (state 2). An emergent state 3 (Mind), accompanied by consciousness, has appeared in some animals, including Man. The ordinary state of Man is characterized by an EEG record exhibiting a frequency of 4 Hz. In plants, spontaneous APs with frequencies one or 2 orders of magnitude less than this have been recorded. Nevertheless, both animals and plants exhibit a type of protoconsciousness in which, even if there is no reasoning or thought, there is sensitive awareness and cognizance of their respective internal, physiological environments and their external, physical environments. Man, however, has developed further capabilities and is able to experience a ‘higher’ state of consciousness. In this case, it may be that the bundling of MTs in neurons has provided the critical mass for a more intense vibration of 40 Hz (recorded from EEG), allowing the emergence of state 4, of self-reflective consciousness, and sometimes also a state 5 (Samadhi). Unfortunately, it is not known how this advancement of consciousness – the steps forward from states 2 and 3 to state 4, and thence to state 5 – have taken place, but it might, on the basis of Orch OR hypothesis, relate to the increasing mass and deployment of MTs in specific cells. The formula developed for the Orch OR hypothesis, τ ≈ Ћ /EG, predicts that, as the self-energy mass of MTs increases, τ, the frequency of quantum reduction events leading to protoconscious impulses, increases. Therefore, a larger EG would be associated with a larger complement of MTs and would lead to a higher rate of EEG-registered vibration (in Hz). But this raises certain questions: Is energy mass EG evaluated in terms of MT number per cell or per tissue? Is the value of EG associated with the spatial arrangement of MTs? Furthermore, is the number of cells bearing parallel and closely arranged MTs, a feature which is characteristic of growing plant cells, also a factor in the evaluation of EG? It is not known to what degree the numbers and arrangements of MTs in animal neurons and plant cells differ, but although individual plant cells mostly have relatively few MTs, bundled or otherwise, when compared to human neurons, certain specialized plant cells, such as the ray parenchyma cells of trees have considerably more. MT density might therefore influence the frequency of OR events but, in plants, MT density may limit the production of self-aware consciousness to trees where MTs are most abundant in cells involved with secondary growth. A Mind (state 3) seems to be a prerequisite for the recognition and acknowledgment of the conscious state in humans. But Mind appears to be an emergent property. Whether or not plants have a ‘mind’ is unanswerable: but plants, especially trees, may have a ‘phyto-mind’, sui generis, to which only they themselves can be present and can comprehend.

A state of conscious mindfulness, or awareness, emerges as an unfolding of the implicate quantum order into the explicated material aspect of existence through the presence of MTs. It is the ability to be consciously aware of the electrical impulses initiated by MTs, and whose passage the MTs direct toward the brain, that releases, or realizes, this potentiality for awareness. Thus, plants probably lag one step behind the experiential world of animals, for although both plants and animals may have attained state 2 (of Brain) and maybe state 3 (of Mind), animals (and humans in particular) have achieved the possibility of self-reflective consciousness (state 4). It is from this last-mentioned auto-generated desire for self-reflection, the property of state 4, that psychological, or psychokinetic, evolution in Man will continue, and will be accompanied by a parallel cultural evolution, as proposed by Gebser.234 On the other hand, Bergson116 was more comprehensive in considering not just human life, but life as a whole: “Now the more we fix our attention on the continuity of life, the more we see that organic evolution resembles the evolution of consciousness, in which the past pushing into the present causes a new form of awareness, incommensurable with what went before.” Acknowledgment of the displacement of the degree of conscious between plants and animals should enable humanity with its higher-grade consciousness and rapid mobility not only to nurture, comprehend and value the relative stillness of the lower-grade plant protoconsciousness, but also for both animals and plants to share mutual experiences through primary perception. This displacement of states of consciousness between plants and animals may be lawful in another way: to maintain the balance of Nature. To paraphrase Bergson (replacing in the following passage, the word ‘cell’ by ‘plant’, and ‘organism’ by ‘ecosystem’), “The component [plant] of an [ecosystem], on becoming momentarily conscious, would barely have outlived the wish to emancipate itself when it would be recaptured by necessity.”235

January 2014, Hameroff and Penrose claimed that the discovery of quantum vibrations in microtubules by Anirban Bandyopadhyay of the National Institute for Materials Science in Japan in March 2013[28] corroborates the Orch-OR theory[13][29] although the paper doesn’t mention quantum vibrations.

In early 2015 it was revealed that pulsed transcranial ultrasound seems to improve memory functioning in Alzheimer’s mice as well as helping to break down amyloid plaques.[30] This could be relevant to Orch-OR. Ultrasound activated latent brain repair and cleanup mechanisms; if it was also helping to boost the disease-weakened cemi field within the neurons in a similar way to adding noise to a signal sometimes boosts it above the noise floor then a similar high frequency ultrasound transmitter tuned to the specific microtubule vibrations could work even in patients in a persistent vegetative state

[Physicists Claim that Consciousness Lives in Quantum State After Death by Janey Tracey 17 June 2014, Astrophysics, Outer Places]

Does quantum mechanics predict the existence of a spiritual “soul”?

*Quantum mechanics predicts some version of “life after death.”

They assert that a person may possess a body-soul duality that is an extension of the wave-particle duality of subatomic particles.

Wave-particle duality, elementary particles, such as photons and electrons, possess the properties of both particles and waves. soul-body dichotomy. there is an existence after death (speaking in purely physical terms). Dr. Hans-Peter Dürr, former head of the Max Planck Institute for Physics in Munich, posits that, just as a particle “writes” all of its information on its wave function, *the brain is the tangible “floppy disk” on which we save our data, and this data is then “uploaded” into the spiritual quantum field. Continuing with this analogy, when we die the body, or the physical disk, is gone, but our consciousness, or the data on the computer, lives on.

*”What we consider the here and now, this world, it is actually just the material level that is comprehensible. The beyond is an infinite reality that is much bigger…. The body dies but the spiritual quantum field continues. In this way, I am immortal,” says Dürr.

Dr. Christian Hellwig of the Max Planck Institute for Biophysical Chemistry in Göttingen, found evidence that* information in our central nervous system is phase encoded, a type of coding that allows multiple pieces of data to occupy the same time. He said, “Our thoughts, our will, our consciousness and our feelings show properties that could be referred to as spiritual properties…

*No direct interaction with the known fundamental forces of natural science, such as gravitation, electromagnetic forces, etc. can be detected in the spiritual.

*On the other hand, however, these spiritual properties correspond exactly to the characteristics that distinguish the extremely puzzling and wondrous phenomena in the quantum world.”

Physicist Professor Robert Jahn of Princeton University concluded that if *consciousness can exchange information in both directions with the physical environment, then it can be attributed with the same “molecular binding potential” as physical objects, meaning that it must also follow the tenets of quantum mechanics. Quantum physicist David Bohm, a student and friend of Albert Einstein, was of a similar opinion. He stated, “The results of modern natural sciences only make sense if we assume an inner, uniform, transcendent reality that is based on all external data and facts. The very depth of human consciousness is one of them.”

These claims if some of the most brilliant minds in quantum mechanics believe that it is consistent with the general patterns and trends of modern science. If if humans do “download” their consciousness into a thus far unobservable field, then a person’s consciousness could, in Dürr’s words, truly be immortal.

[Biocentrism: How Life and Consciousness are the Keys to Understanding the True Nature of the Universe Paperback – May 18, 2010 by Robert LanzaBob Berman]

Biocentrism: How Life and Consciousness Are the Keys to Understanding the Nature of the Universe“ contains a notion that life does not end when the body dies, and it can last forever.

↓↓Biocentrism teaches that life and consciousness are fundamental to the universe. It is consciousness that creates the material universe, not the other way around.

Lanza points to implying intelligence existed prior to matter.

He also claims that space and time are not objects or things, but rather tools of our animal understanding.

theory implies that death of consciousness simply does not exist.

They incorrectly believe according to Lanza, that the body is going to perish, sooner or later, thinking their consciousness will disappear too.

If the body generates consciousness, then consciousness dies when the body dies. But if the body receives consciousness in the same way that a cable box receives satellite signals, then of course consciousness does not end at the death of the physical vehicle.

↓↓In fact, consciousness exists outside of constraints of time and space. It is able to be anywhere: in the human body and outside of it.

Lanza also believes that multiple universes can exist simultaneously. In one universe, the body can be dead.And in another it continues to exist, absorbing consciousness which migrated into this universe.

This means that a dead person while traveling through the same tunnel ends up not in hell or in heaven, but in a similar world he or she once inhabited, but this time alive. And so on, infinitely. It’s almost like a cosmic Russian doll afterlife effect.

These are the physicists and astrophysicists who tend to agree with existence of parallel worlds and who suggest the possibility of multiple universes.

Multiverse (multi-universe) is a so-called scientific concept, which they defend. They believe that no physical laws exist which would prohibit the existence of parallel worlds.

The first one was a science fiction writer H.G. Wells who proclaimed in 1895 in his story “The Door in the Wall”.

And after 62 years, this idea was developed by Dr. Hugh Everett in his graduate thesis at the Princeton University. It basically posits that at any given moment the universe divides into countless similar instances.

And the next moment, these “newborn” universes split in a similar fashion. In some of these worlds you may be present: reading this article in one universe, or watching TV in another.

The triggering factor for these multiplying worlds is our actions, explained Everett. If we make some choices, instantly one universe splits into two with different versions of outcomes.

In the 1980s, Andrei Linde, scientist from the Lebedev’s Institute of physics, developed the theory of multiple universes. He is now a professor at Stanford University.

Linde explained: Space consists of many inflating spheres, which give rise to similar spheres, and those, in turn, produce spheres in even greater numbers, and so on to infinity.

In the universe, they are spaced apart. They are not aware of each other’s existence. But they represent parts of the same physical universe.

The fact that our universe is not alone is supported by data received from the Planck space telescope.

So, there is abundance of places or other universes where our soul could migrate after death, according to the theory of neo-biocentrism. But does the soul exist?

Is there any scientific theory of consciousness that could accommodate such a claim?

According to Dr. Stuart Hameroff, a near-death experience happens when the quantum information that inhabits the nervous system leaves the body and dissipates into the universe.

Contrary to materialistic accounts of consciousness, Dr. Hameroff offers an alternative explanation of consciousness that can perhaps appeal to both the rational scientific mind and personal intuitions.

Consciousness resides, according to Stuart and British physicist Sir Roger Penrose, in the microtubules of the brain cells, which are the primary sites of quantum processing.

Upon death, this information is released from your body, meaning that your consciousness goes with it.

They have argued that our experience of consciousness is the result of quantum gravity effects in these microtubules, a theory which they dubbed orchestrated objective reduction (Orch-OR).

Consciousness, or at least proto-consciousness is theorized by them to be a fundamental property of the universe, present even at the first moment of the universe during the Big Bang.

“In one such scheme proto-conscious experience is a basic property of physical reality accessible to a quantum process associated with brain activity.”

Our souls are in fact constructed from the very fabric of the universe – and may *have existed since the beginning of time. Our brains are just receivers and amplifiers for the proto-consciousness that is intrinsic to the fabric of space-time.

So is there really a part of your consciousness that is non-material and will live on after the death of your physical body?

* Dr Hameroff told the Science Channel’s Through the Wormhole documentary:

“Let’s say the heart stops beating, the blood stops flowing, the microtubules lose their quantum state.

↓↓ ****The quantum information within the microtubules is not destroyed, it can’t be destroyed, it just distributes and dissipates to the universe at large”.

Robert Lanza would add here that not only does it exist in the universe, it exists perhaps in another universe.

If the patient is resuscitated, revived, this quantum information can go back into the microtubules and the patient says “I had a near death experience”‘

He adds: “If they’re not revived, and the patient dies, it’s possible that this quantum information can exist outside the body, perhaps indefinitely, as a soul.”

This account of quantum consciousness explains things like near-death experiences, astral projection, out of body experiences, and even reincarnation without needing to appeal to religious ideology.

*Energy never dies or ceases to exist.

* “The energy of your consciousness potentially gets recycled back into a different body at some point, and in the meantime it exists outside of the physical body on some other level of reality, and possibly in another universe.”* [Quantum Theory Proves Consciousness Moves To Another Universe At Death, Jan 19, 2014]

The relationship between black holes and galaxies:  Like discovering a neighborhood house assumed to be vacant is actually inhabited, over the past decade researchers realized that most galaxies have at least one black hole in residence in their central regions. But these black holes aren’t the stellar variety with three to ten times the mass of our Sun. Their size swamps the imagination- they have millions, sometimes billions, of solar masses. Even our home galaxy, the Milky Way, has a four million solar mass black hole located at its center, about 27,000 light years from Earth. Galactically speaking, that places it in our own backyard! Well, there goes the neighborhood!

At the heart of virtually every large galaxy lurks a supermassive black hole with a mass of a million to more than a billion times our Sun. Most of these black holes are dormant, but a few per cent are ‘active’ meaning that they are drawing material from their host galaxy inwards, This forms an accretion disc that feeds the black hole.

As the material spirals through the disc toward the event horizon, it gains fantastic speed and releases vast amounts of energy. As a result, some of the disk material does not fall in because its speed achieves escape velocity. This material is slung around to one of the poles and expelled as a powerful jet traveling near the speed of light. We also now know that supermassive black holes are inexorably linked to the galaxies that encircle them.

For example, the size of a supermassive black hole appears to have a direct correlation to the galaxy where it exists. Almost a decade ago, researchers calculated that the mass of a supermassive black hole appeared to have a constant relation to the mass of the central part of its galaxy, known as its bulge (think of the yolk in a fried egg). This 1 to 700 relationship supports the notion that the evolution and structure of a galaxy is closely tied to the scale of its black hole.

Other studies found another strong correlation. This one was between the mass of a supermassive black hole and the orbital speed of stars in the outer regions of their galaxy where the direct gravitational influence of the supermassive black hole should be weak: the larger the black hole, the faster the outer stars travel.

Thus it’s now believed that black holes are not only common throughout the Cosmos but they play a fundamental role in the formation and evolution of the Universe we inhabit today.

In fact, we would not be here without them.

History Galactica

Most astronomers believe that the Universe began about 15 billion years ago with an explosion known as the Big Bang. All the matter in the Universe, all the space and even time, itself, was released during this event.

Hundreds of millions of years followed before matter started to collect into vast clouds then coalesce and collapse, under its own weight, into the first stars.

The first stars were huge, hot and powerful. They consumed vast amounts of material and therefore only shined for a few hundred million years. For comparison, our Sun has been shining for over four and a half billion years.

When the nuclear fuel powering the first stars became exhausted, the explosion that followed threw off material that became incorporated into the next generation of suns. But, due to their prodigious mass, their cores continued to shrink until they became gigantic black holes, millions to billions of times more massive than our Sun.

The life of a star :  Stars are created when vast clouds of hydrogen gas and other material fall in upon themselves due to their own weight. This can be provoked by the gravity of a passing star or the arrival of pressure waves from a supernova explosion that introduces instability by nudging one side of the cloud. As it collapses, the cloud breaks into smaller and smaller pieces. In each of these fragments, gravity begins to release heat energy and the fragment condenses into a rotating sphere of super hot gas known as a protostar.

Over time, the pressure and temperature within the protostar becomes so intense that a continuous thurmo- nuclear explosion is triggered. With the onset of this chain reaction, hydrogen begins to fuse into the next heavier element, helium. The force of this ongoing, relentless release of energy pushes outward until it reaches an equilibrium with gravity and, as a result, the cloud stops collapsing. Once the radiation from the internal explosion reaches the cloud’s edge, it escapes into space as light and thus a star is born.

When the non-stop internal nuclear explosion that powers a star has converted its hydrogen into helium, the star inflates and begins a new round of energy release by converting helium into carbon then carbon into oxygen followed by other elements up the periodic table. In essence, stars are factories that create the material comprising everything in our world- including ourselves. However, these new fuel sources are depleted at faster and faster rates until the star begins to produce iron at its core.

Unfortunately, iron cannot be used as nuclear fuel, so the thermonuclear activity at the star’s core begins to shut down. When the core stops releasing enough energy to prevent the constant crush of gravity from taking over and squeezing it inward, the star collapses in the wink of an eye. For example, if a star contains less that two or three times as much material as our Sun, then the force of the sudden inward rush will rip it apart in an titanic explosion called a supernova. The explosion exposes the star’s core- a dense, city-sized ball of material made only of atomic neutrons– and it slowly begins to cool.

However, if the star contains more than three times the mass of our Sun, then the star’s core will continue to shrink until it becomes an infinitely small object with all the mass of its former self. Astronomers call this a black hole– the bottomless pit in the fabric of space-time that Schwarzschild discovered in Einstein’s equations.
These first black holes were both destroyers and creators- swallowing material that came too close while throwing jets of high-energy particles and radiation generated by their violent feeding frenzy. The jets, which can be millions of light-years in length, are believed to have triggered the formation of successive stellar generations and thus seeded the first galaxies with starlight. Therefore, these original supermassive black holes most likely arose prior to and helped in the creation of the galaxies that continue to spin about them. They were essential to galactic evolution (they still are!) and, in the long run, to the creation of our Sun, our planet andour very existence. They are both the the universal omega and the cosmic alpha.

Through the event horizon: This amazing animation models the 4 million solar mass supermassive black hole at the center of our Galaxy, the Milky Way. It places the viewer inside the accretion disk as they travel towards and through the event horizon.

The tidal force from the supermassive black hole is weak enough that you can survive all the way down to the inner horizon without being torn apart.
Galaxies can be divided into two distinct categories based on the feeding status of their supermassive central resident. Inactive galaxies, for example, have supermassive black holes in quiescence- like a satiated cosmic beast, they sleep in between meals. Examples include our Milky Way galaxy, NGC 3031 (M81)NGC 5457 (M101) and NGC 891.

But dormancy can be temporary. If a star strays too close or a cloud of gas and dust ventures into the black hole’s accretion disc, the black hole will awaken, become active and release vast amounts of energy and potentially lethal radiation that reverberates throughout its galaxy. An active galaxy is no place to be or venture near. Examples include NGC 1275 (pictured at the top of the previous page), NGC 1097NGC 4258, and NGC 5033.

NGC 4258 : Since the early 1960s, NGC 4258, also known as M106, has been known to exhibit an extra pair of arms, located between the spiral arms comprised of stars, dust and gas. But an explanation for their existence remained elusive until earlier in this decade. NGC 4258 is located in the northern constellation of Canes Venatici approximately 21 million light years from Earth,

Located in the northern constellation of Canes Venatici, NGC 4258 (M106) has been know to have a mysterious extra set of arms for many decades. Shown here in vivid red, the extra appendages are now known to be caused by a high energy jet emanating from the supermassive black hole in the galaxy’s center. The jet creates a shock wave that excites material in the galaxy’s halo, seen here in the ionized light emitted by hydrogen atoms.

Seen in the light emitted by hydrogen molecules when they become ionized, these arms display an artificial red hue to make them visible in the image that accompanies this article. The extra arms are now believed to be caused by high energy jets emanating from the galaxy’s active 40 million solar mass central supermassive black hole.

Because the jets are tilted at a low inclination they pierce the disk and surrounding halo of this galaxy. So, as the jets pass through regions of gas, they create an expanding cocoon of shock waves that heats the surrounding material causing it to release radiation in optical wavelengths. The curvature and fraying seen at their extremities represents previous trajectories of the jet due to past precession. Precession is a change in the orientation of the rotation axis of a spinning object. For example, the wobble of a spinning top.

Interestingly, water molecules in the accretion disk surrounding the supermassive black hole at the center of NGC 4258 have become so excited that they amplify microwave radio emissions in a manner similar to the way in which a laser amplifies light. These powerful naturally-occurring microwave amplifiers are called masers. The discovery and measurement of the masers in this galaxy have made distance estimates between Earth and other galaxies more precise.

NGC 5033 : Most galaxies are located in a group with other galaxies and even these are organized into larger associations called super clusters. They are formed at the junction of large gravitational bubbles that seem to fill the Universe. Galaxies are in constant motion within their cluster and, over time, they may approach, collide and combine. This is the way galaxies grow and evolve- most galaxies have interacted with others at one time or another since they were formed. Mergers are thought to have contributed significantly to the growth of galaxies- the early universe was much smaller and incredibly crowded therefore galaxies were more likely to collide.

The sprial galaxy NGC 5033, located near the northern Big Dipper in the constellation of Canes Venatici, has two supermassive black holes which indicate that the star system survived a merger with another galaxy sometime in the past. Eventually, the black holes will collide releasing titanic amounts of energy causing the galaxy to become even more disturbed than seen in this recent view

If two galaxies merge, so should their central black holes. Recent computer modeling speculates the event would be violent, unleashing tremendous energy as trapped gas rushes between the two black holes. Galactic mergers take millions of years to complete but there are plenty of examples for astronomers to study.

For instance, located about 37 million light years from Earth in the constellation of Canes Venatici NGC 5033 displays evidence of major activity driven, in part, by two supermassive black holes located in its central region. It’s suspected that the second black hole was acquired sometime in the past when NGC 5033 survived a merger with another galaxy. This merger resulted in much of the turbulence and apparent chaos taking place inside this star system. New stars are being born at a furious rate. Over time, the pair of supermassive black holes will gradually get closer and eventually crash into one another. The dramatic collision will unleash intense radiation, gravitational waves and ripples in the fabric of space-time as predicted by Einstein.

The waterfall’s edge : Although black holes started as a mathematical curiosity that was tolerated by the established scientific community of the early twentieth century, over the decades since Einstein suggested and Schwarzschild revealed their nature, science now sees them as indispensable forces of creation and the sculptors of mighty galaxies.

But, this new understanding compels some to indulge in a bit of speculation that’s evocative, intriguing and somewhat disquieting. Could it be possible that the Big Bang was simply the consequence of some universal black hole that accreted all the matter of a previous Universe, imploded then exploded resulting in the Cosmos where human mankind exists?

For some, it’s not only possible but most likely probable.

For example, imagine crossing the event horizon of a black hole. Like plungling in a basket over Niagara, once it’s crossed there’s no hope of return- you will fall into the singularity and there is nothing that can prevent it. At the same time, you will never receive information from anything that may have preceded and is located closer to the singularity than your current position because no information can escape from within. You can only know about where you are and that which is behind you. Isn’t this very similar to the way time functions in our Universe? While we move forward into tomorrow, there is no way for us to know anything about it beforehand. We only have knowledge about the present and all our yesterdays.

So, what’s it like to journey past a black hole’s event horizon? Some would respond, “Simply look around you.”

These ponderings have the earmarks of metaphysical philosophy. Most likely, they can and never will be provisionally confirmed or completely dismissed. Yet, they stir our blood and awaken our yearning to pursue the most fundamental questions of all: where did the Universe, and therefore we ourselves, come from and what waits just over the waterfall’s edge.
