Francis Crick is one of the most extraordinary biographical coincidences in the history of science. In 1953, with James Watson, he co-discovered the double helix structure of DNA — the molecule that encodes the instructions for building every living thing on Earth, including the brain. Then, in the final decades of his life, Crick turned his attention to what he considered science’s deepest remaining problem: the neuroscience of consciousness. He called his proposal ‘The Astonishing Hypothesis’ — the idea that consciousness arises entirely from the firing of neurons.

One person, two questions: What is the code of life? And who is reading it?

The same question has been asked in a different language for three thousand years in the Upanishadic tradition. The Kena Upanishad — one of the oldest of the principal Upanishads — opens with what remains the most precise ancient statement of what modern philosophy calls the hard problem of consciousness: by whom directed does the mind go toward its objects? By what power does the eye see? And what is that which cannot itself be seen — the seer that sees all things but cannot be captured as an object of sight?

In May 2025, Oxford Academic published a peer-reviewed paper with a striking title: ‘A quantum microtubule substrate of consciousness is experimentally supported.’ The paper argued that the protein structures inside neurons — microtubules, encoded by TUBB genes in your DNA — are the biophysical substrate of conscious moments. The gap between the Kena Upanishad and Oxford Academic is approximately 2,700 years. The question they are addressing is the same.

This article examines five points where the genetics and neuroscience of consciousness and the Darshana traditions converge — not as a forced integration or a spiritual endorsement of science, but as two independent traditions of rigorous inquiry arriving at the same fundamental questions, and sometimes at remarkably similar answers.

Before examining what DNA and Darshan say about consciousness, it is worth being precise about what consciousness actually is — because the word is used so loosely in everyday language that its philosophical weight is easily lost.

Consciousness is not intelligence. It is not information processing. It is not complex behaviour or the ability to respond flexibly to the environment. A thermostat does all of these things in a primitive sense. What consciousness is — and what makes it philosophically unique — is subjective experience. The felt quality of seeing the colour blue. The particular texture of a memory. The sense of existing as a self in a moment that has a now.

The philosopher Thomas Nagel captured this in his famous formulation: there is something it is like to be a bat — some felt quality of existence from the bat’s point of view — that cannot be captured in any third-person description of bat neurology. There is something it is like to be you, reading these words, that cannot be captured in any description of your neuronal firing patterns, however precise.

The Easy Problems and the Hard Problem

David Chalmers, in his 1995 paper and 1996 book The Conscious Mind, drew a distinction that has organised consciousness research ever since. The easy problems of consciousness are explaining how the brain integrates information, discriminates stimuli, reports mental states, focuses attention, and controls behaviour. These are called easy not because they are simple but because they are tractable — they can in principle be solved by identifying the right neural mechanisms. Progress on them is rapid.

The hard problem is different in kind. It is explaining why any of this neural processing is accompanied by subjective experience at all. Why does it feel like something to process visual information, rather than merely processing occurring in the dark? Why does the firing of photoreceptors in your retina produce the felt quality of seeing red, rather than simply triggering a cascade of neural computation?

No current scientific theory has solved or substantially addressed the hard problem. As of the Barcelona Science of Consciousness Conference in July 2025 — the field’s largest annual gathering — the hard problem remains the central unresolved question in the science of mind. Chalmers himself noted that progress has been ‘frustratingly slow despite enormous investment in neuroscience.’ The Kena Upanishad identified this problem approximately 2,600 years before Chalmers named it.

Neural Correlates of Consciousness — What We Know

Francis Crick and Christof Koch established the neural correlates of consciousness framework — the search for the minimal neural mechanisms sufficient for specific conscious experiences. Decades of research have produced detailed maps of which neural systems are active during different conscious states. The thalamus, claustrum, and prefrontal-parietal networks are consistently implicated. Gamma oscillations — brain waves at approximately 40 cycles per second — correlate reliably with conscious states across species. Anaesthesia, which abolishes consciousness, disrupts these oscillatory patterns.

This research is extraordinarily valuable — and it is not an answer to the hard problem. It tells us what the brain is doing when consciousness occurs. It does not tell us why doing those things produces experience rather than merely processing. The neural correlates of consciousness are, at best, the material conditions for consciousness. Whether they are its cause, its substrate, or its occasion is the question that remains open.

Your DNA — the approximately 3.2 billion base pairs that encode your genome — does not encode consciousness directly. What it encodes is everything required to build and operate the biological machinery through which consciousness occurs. Understanding what DNA actually builds helps clarify both the power and the limits of a genetic account of conscious experience.

What TUBB Genes Build — And Why It Matters

The TUBB gene family encodes tubulin proteins — the building blocks of microtubules. Microtubules are hollow protein cylinders approximately 25 nanometres in diameter that form the internal scaffolding of cells, including neurons. In neurons, microtubules serve structural functions — maintaining the shape of axons and dendrites, facilitating the transport of molecules within neurons, and organising the synaptic machinery that transmits signals between neurons.

For most of neuroscience’s history, microtubules were considered purely structural. The Orch OR theory of Penrose and Hameroff proposed something dramatically different: that quantum computations occurring inside microtubules — specifically, the quantum coherence of electron states in tubulin proteins — are the physical substrate of conscious moments. Each quantum wave function collapse, in Penrose’s framework called objective reduction, corresponds to a moment of conscious experience.

This is a remarkable claim. If it is correct, then DNA — specifically the TUBB genes — encodes not just the structural elements of neurons but the quantum hardware of consciousness itself. The 2024 Frontiers in Neuroscience paper by Avila, Marco, and colleagues proposed that EEG gamma waves — the oscillations most reliably correlated with conscious states — may be generated by microtubule changes in dendrites and cell soma rather than axonal firing. This would mean that the neural correlate of consciousness and the quantum substrate proposed by Orch OR are the same physical phenomenon viewed at different scales.

The 2025 Oxford Experimental Support for Orch OR

In May 2025, Michael C. Wiest published a landmark paper in Neuroscience of Consciousness — Oxford Academic’s leading consciousness research journal. The paper’s title announces its significance: ‘A quantum microtubule substrate of consciousness is experimentally supported and solves the binding and epiphenomenalism problems.’

The experimental support comes from multiple independent lines of evidence converging on the same conclusion: inhalational anesthetics — compounds as structurally diverse as xenon, halothane, isoflurane, and desflurane — act primarily on microtubules to produce unconsciousness. The famous Meyer-Overton correlation, observed since the 1890s, shows that anesthetic potency correlates with lipid solubility across orders of magnitude — a pattern consistent with action on a single conserved hydrophobic molecular target. Wiest argues that this target is tubulin in microtubules.

If diverse anesthetic compounds all abolish consciousness by acting on microtubules, and if microtubules are the biophysical substrate of conscious moments as Orch OR proposes, then the experimental prediction of Orch OR — that anesthetics should target microtubules — is confirmed. This does not prove that quantum computations in microtubules produce consciousness. But it provides the strongest experimental support yet that microtubules are not peripheral to consciousness but central to it.

The Upanishadic tradition’s engagement with consciousness is not theology, mythology, or speculation. It is the product of a systematic contemplative investigation of subjective experience — using the instrument of consciousness to examine consciousness itself. The precision of its conclusions is remarkable when read in the context of current consciousness research.

The Kena Upanishad — The Hard Problem in Ancient Form

The Kena Upanishad opens with a question: Keneshitam patati preshitam manah — By whose will directed does the mind go toward its objects? The text proceeds to define consciousness in terms that a contemporary philosopher of mind would recognise as addressing the hard problem directly.

‘That which is not thought by the mind, but by which the mind thinks — know that alone as Brahman, not this which people worship here. That which is not seen by the eye, but by which the eye sees — know that alone as Brahman. That which is not heard by the ear, but by which the ear hears — know that alone as Brahman’.

The Upanishad is making a precise logical point: the knowing faculty cannot be known by the faculties it enables. The observer cannot be reduced to an object of observation. Consciousness cannot be seen, because it is that by which seeing occurs. This is not mysticism — it is the same logical structure that makes the hard problem hard. You cannot explain the observer by describing the neurological processes it observes, because the description itself requires an observer.

Samkhya — Purusha and Prakriti

The Samkhya Darshana — one of the six classical schools of Indian philosophy — provides the most systematic ancient framework for the mind-body problem. It distinguishes between two fundamental principles: Purusha (pure consciousness — the unchanging, witnessing awareness) and Prakriti (matter — everything in the physical and mental world, including thoughts, sensations, DNA, neurons, and microtubules).

In Samkhya, consciousness (Purusha) never acts. It only witnesses. Prakriti acts — it evolves, combines, and produces the entire manifest world, including the mind, the senses, and the body. But without Purusha’s witnessing presence, Prakriti’s activity would occur in complete darkness — unobserved, unlived, unexperienced.

This maps with striking precision onto the hard problem. Neuroscience describes Prakriti — the neural mechanisms, the information processing, the microtubule quantum computations. What it cannot describe is Purusha — the witnessing awareness that makes the neural processing experienced rather than merely occurring. The hard problem is precisely the question of how Prakriti-level processes give rise to Purusha-level experience. Samkhya’s answer — that they do not give rise to it because Purusha is ontologically prior to Prakriti — is the most radical possible response to the hard problem.

Tat Tvam Asi and Aham Brahmasmi — Identity of Individual and Universal

The Chandogya Upanishad’s Tat Tvam Asi (That Thou Art) and the Brihadaranyaka Upanishad’s Aham Brahmasmi (I am Brahman) represent the Advaita Vedanta culmination of the consciousness inquiry: the individual Atman is identical with Brahman — universal consciousness. Individual conscious experience is not an isolated epiphenomenon of a particular brain but a localised expression of the same consciousness that pervades reality.

The convergence with modern physics here is subtle but significant. Integrated Information Theory proposes that consciousness is a fundamental property of information integration — potentially present at multiple scales of the universe, not exclusive to biological systems with nervous systems. If consciousness is fundamental rather than emergent — if it is a feature of reality rather than a product of biological complexity — then the Advaita identification of individual and universal consciousness is not philosophically incoherent but may be pointing toward the same ontological territory that IIT is attempting to formalise mathematically.

5 Convergences Between Neuroscience and Darshan

Convergence	Neuroscience	Darshan
The observer problem	Neural correlates cannot explain the observer; the hard problem is unresolved (Chalmers 1995, confirmed 2025)	Kena Upanishad: consciousness is that by which knowing occurs — it cannot be known as an object
Consciousness as fundamental	Integrated Information Theory: phi as a fundamental property potentially present throughout reality (Tononi)	Advaita Vedanta: consciousness (Brahman) is the fundamental ground of reality, not a product of matter
Matter vs. awareness distinction	Hard problem separates physical processes (easy) from subjective experience (hard)	Samkhya Darshana: Prakriti (matter) and Purusha (consciousness) are ontologically distinct
Bi-directional influence	Epigenetics: mental states alter gene expression; consciousness shapes its biological substrate	Yoga tradition: Sadhana modifies Samskaras and the physical constitution — observer shapes the observed
Quantum substrate of experience	Orch OR 2025: microtubules (encoded by TUBB genes) are the quantum biophysical substrate of conscious moments	Mandukya Upanishad: consciousness has subtle states beyond ordinary waking — Turiya as the witnessing ground

For the philosophical framework of the six classical Indian Darshana schools within which the Upanishadic consciousness map sits, see Six Schools of Indian Philosophy: The Shad Darshanas Explained (TheQuestSage.com). For the relationship between quantum physics and Vedantic philosophy more broadly, see Advaita Vedanta and Modern Science: 5 Remarkable Convergences (TheQuestSage.com).

The standard model of the relationship between DNA and consciousness is one-directional: genes encode the biological structures through which consciousness occurs. What epigenetics reveals is that this relationship operates in both directions. Consciousness — in the form of sustained mental states, practices, and experiences — actively modifies gene expression. The observer shapes the substrate through which it observes.

Richard Davidson’s research at the University of Wisconsin-Madison documented changes in gene expression in experienced meditators within hours of intensive mindfulness practice — particularly in genes governing inflammatory pathways, including NF-κB-related regulatory genes. These are not trivial changes: NF-κB-mediated inflammation is implicated in depression, cardiovascular disease, and accelerated aging. The mental state of sustained meditative attention produces measurable molecular changes in the very DNA that supports neural function.

Elizabeth Blackburn’s Nobel Prize-winning research on telomeres — the protective caps on chromosomes that shorten with each cell division and with chronic stress — provided another dimension of the same story. Chronic psychological stress shortens telomeres, accelerating cellular aging. Mindfulness-based stress reduction and regular meditation slow or reverse telomere shortening. The quality of one’s relationship with one’s own mind affects the molecular clocks ticking in every cell of one’s body.

The Yogic tradition’s claim that sustained inner practice transforms the practitioner’s physical and mental constitution — that Sadhana modifies the Samskaras (deep impressions) that shape perception and response — is not metaphor in the light of epigenetics. It is a description of a real molecular mechanism: the experience of the observer actively modifies the substrate that generates future observation.

Here is the honest assessment: the neuroscience of consciousness is one of the most exciting and productive fields in contemporary science. The Orch OR experimental support of 2025, the refinement of the hard problem, the epigenetics of mental states — these are genuine advances. And yet the hard problem remains hard. The observer remains unexplained.

Every scientific theory of consciousness — Orch OR, IIT, Global Workspace Theory, Higher Order Theory — describes conditions under which consciousness occurs. None explains why any physical process produces experience rather than merely process. This is not a criticism of neuroscience — it may be that the hard problem is not empirically solvable, because the instrument of observation (consciousness) cannot be made into its own object of study through third-person methods.

The Darshana traditions reached this conclusion long ago. The Kena Upanishad’s observation — that consciousness cannot be grasped as an object because it is the subject of all grasping — is not an admission of ignorance but a precise logical statement about the limits of objective inquiry. The Yogic traditions propose that consciousness can be investigated directly through systematic inner inquiry: Vichara (self-inquiry), Dhyana (meditation), and Samadhi (deep contemplative absorption). These are not alternatives to neuroscience — they are complementary methods for a domain that objective science can approach but not fully enter.

I want to say something about why this question — the genetics of consciousness, the relationship between DNA and the observer — matters beyond academic philosophy and neuroscience.

We live in an era of extraordinary scientific power over biological systems. CRISPR genome editing can alter DNA sequences with precision that would have seemed miraculous a generation ago. Neuropharmacology can modify consciousness states with increasing specificity. Brain-computer interfaces are beginning to bridge the biological and the digital. And artificial intelligence is producing systems that process information with capabilities that increasingly resemble — and in some domains exceed — human cognition.

All of this power is being wielded in the context of profound uncertainty about what consciousness actually is. We can edit the genome that builds the brain, but we do not know who — or what — lives in that brain. We can modify neural states with drugs and devices, but we have not resolved the question of whether there is a Purusha witnessing those states that is different in kind from the states themselves. We are accumulating extraordinary technological power over the substrate of consciousness without having understood the consciousness that is being affected.

The Darshana traditions do not resolve this uncertainty with comfortable answers. The Kena Upanishad does not tell you that consciousness is produced by microtubules or that it is separate from them. It points you toward a direct investigation that can only be conducted in the first person. The Samkhya distinction between Purusha and Prakriti is not a scientific finding — it is a phenomenological map to be verified in one’s own experience through the practices the tradition prescribes.

What the convergence between neuroscience and Darshan suggests, at minimum, is this: the question of consciousness is the most important question a human civilisation can ask, precisely because it underlies every other question about what we should do with our technological power, how we should treat other beings, what makes a human life significant, and what survives when the biological hardware that DNA built eventually fails.

Francis Crick discovered the code of life and spent his final years searching for the reader. The Kena Upanishad identified the reader as that which cannot be found among the objects of search — because it is the searching itself. Both traditions are pointing at the same territory. The instruments they use are different. The humility the territory demands is the same.

The question of consciousness is not only philosophical. It has direct practical dimensions for how you live, what you attend to, and how you understand your own experience.

• Investigate directly. The Darshana traditions propose that consciousness can be examined through systematic inner inquiry — not through believing doctrines but through the actual practice of Vichara (self-inquiry as taught in the Advaita tradition), Dhyana (sustained meditative attention), or simply the practice of noticing the noticing: who is aware of your awareness? This is not spiritual bypassing — it is the first-person science that the third-person neuroscience cannot conduct for you.
• Take epigenetics seriously. Your mental states — your chronic patterns of anxiety, rumination, resentment, or their alternatives — are actively modifying your gene expression. The quality of your consciousness is writing itself into your biology. Meditation, regular contemplative practice, and the cultivation of psychological equanimity are not luxuries. They are interventions at the molecular level of your own substrate.
• Hold the hard problem lightly. You do not need to resolve the relationship between consciousness and DNA to live well. But holding the question openly — neither collapsing it into a simple materialism that dismisses the observer nor escaping into spirituality that dismisses the biology — keeps you honest about the genuine mystery of what you are.
• Read the Kena Upanishad. It is short — fewer than forty verses. It was composed approximately 2,700 years ago. It addresses the hard problem of consciousness with a precision that current philosophy has not improved upon. Reading it alongside the 2025 Oxford Academic paper on microtubule consciousness is an unusual but genuinely illuminating experience.

The genetics of consciousness is a field in its early stages. DNA encodes the tubulin proteins that build microtubules. Microtubules — according to the Orch OR theory, now with experimental support from Oxford Academic’s 2025 publication — may be the quantum biophysical substrate of conscious moments. Epigenetics demonstrates that the relationship between consciousness and DNA runs in both directions: mental states modify gene expression, and sustained inner practice can alter the biological substrate at the molecular level.

None of this answers the hard problem. None of it explains why any of this quantum computation in microtubules produces experience rather than merely computation. The observer remains elusive in the third-person language of science — as the Kena Upanishad said it would.

The Samkhya distinction between Purusha and Prakriti, the Advaita identity of Atman and Brahman, the Kena Upanishad’s precise phenomenological definition of consciousness as prior to its neural conditions — these are not mythological add-ons to the neuroscience. They are the most sophisticated available framework for the dimension of consciousness that neuroscience has not yet reached and may not be able to reach through third-person methods alone.

Two traditions, three thousand years apart, pointing at the same irreducible mystery. Francis Crick encoded in one life the question they share. The answer, if there is one, may require both the rigour of science and the depth of the Darshana traditions that first asked it.
