In a bold challenge to centuries of scientific orthodoxy, renowned neuroscientist Christof Koch is calling for a fundamental rethinking of consciousness — not as an emergent byproduct of brain activity, but as something deeper, older, and more universal than we’ve ever imagined.

At the upcoming 15th Behind and Beyond the Brain Symposium hosted by the BIAL Foundation in Porto (April 8–11, 2026), Koch will present a radical perspective: Consciousness may not be generated by the brain at all — it could be woven into the very fabric of reality itself.

The “Hard Problem” That Refuses to Be Solved

For decades, science has operated under the assumption that consciousness arises from complex neural computations in the brain. But despite unprecedented advances in neuroscience — from functional MRI scans to detailed mapping of neural circuits — one profound question remains unanswered: Why does subjective experience exist at all?

This is known as the “hard problem” of consciousness — a term coined by philosopher David Chalmers. It’s not enough to explain how the brain processes information; we still can’t say why there’s an inner world behind our eyes, why pain feels like pain or red looks like red.

“We’ve mapped more neurons than ever before,” Koch says, “but when it comes to explaining subjective experience — that ‘what it is like’ to be alive — we’re no closer than Descartes was. Something’s missing.”

Three Challenges to Materialism

Koch’s argument rests on three mounting challenges to the current materialist paradigm:

1. The Limits of Neural Reduction
   Even with detailed brain activity maps, science cannot yet explain how subjective states—like the taste of wine or the feeling of joy—emerge from electrical and chemical signals in neurons.
2. Physics Questions Reality Itself
   Modern physics — particularly quantum mechanics and cosmology — increasingly suggests that reality is far stranger than classical materialism allows. The universe may not be fundamentally physical at its core, but deeply interconnected and information-rich.
3. Unexplained Phenomena Persist
   From near-death experiences (NDEs) where people report vivid awareness during clinical death, to moments of terminal lucidity — sudden bursts of clarity in dying patients with severe dementia — these phenomena defy explanation within traditional neuroscience.

“Why would the brain produce a full consciousness experience when it’s no longer functioning?” Koch asks. “And why do so many across cultures describe similar patterns: light, peace, out-of-body sensations?”

Consciousness as Fundamental: A New Scientific Framework

Koch doesn’t propose abandoning science — he proposes expanding its foundations.

Drawing on philosophical traditions like panpsychism (the idea that consciousness is a fundamental feature of all matter) and idealism (that mind underlies reality), Koch argues we must consider consciousness not as an accident of biology, but as a universal property.

He supports Integrated Information Theory (IIT) — a scientifically grounded model developed by him and Giulio Tononi — which posits that any system with sufficiently complex integrated information possesses some form of subjective experience. The more integration, the higher the level of consciousness.

“A rock may have a tiny amount of awareness,” Koch explains. “The human brain has much more. But so do bees, maybe even ecosystems.”

This framework transforms panpsychism from metaphysics into testable science — offering measurable predictions about where and how consciousness arises in nature.

A Legacy of Innovation

Christof Koch is no outsider to this field. As a former professor at MIT and Caltech, and now chief scientist at the Allen Institute for Brain Science, he has spent decades pushing the boundaries of neuroscience.

His groundbreaking work includes developing new methods to detect hidden awareness in patients diagnosed as being in a vegetative state — proving that many are conscious but unable to respond due to paralysis or neurological damage.

“By asking smarter questions and using better tools,” Koch says, “we’ve already discovered that consciousness is more nuanced than we thought. Now we must ask: what if it’s not just in the brain — but everywhere?”

Toward a New Science of Consciousness

The symposium in Porto will bring together leading thinkers from neuroscience, philosophy, physics, and medicine to debate these ideas.

Koch’s vision isn’t about replacing science with mysticism. It’s about expanding science to include consciousness as a fundamental element of nature — just like mass or energy.

“If the universe is full of information, entanglement, and interconnectedness,” he says, “then why not assume that consciousness plays its own role in shaping reality?”

In 2026, we may finally be ready to ask: Is consciousness not a product of the brain — but one of the deepest laws of nature?
