For many years, neuroscientists have searched the brain for the biological basis of consciousness, assuming our ideas, feelings, and subjective experiences emerge from networks of neurons.
However what if that assumption is incomplete?
That is the provocative query explored by neuroscientist Christof Koch of the Allen Institute in Seattle.
Koch lately offered his ‘challenges’ to our understanding of consciousness on the Bial Basis’s ‘Behind and Beyond the Brain‘ symposium in Porto, Portugal, in April 2026 – constructing on a physique of revealed work that features this 2016 paper in Nature Reviews Neuroscience.
Koch defined to ScienceAlert that it could be time to rethink one in all neuroscience’s deepest assumptions: that consciousness is one thing the mind produces.
Koch doesn’t dispute the mind’s important function in acutely aware expertise.
Many years of analysis have proven that accidents, illness, anesthesia, and electrical stimulation can profoundly alter – and even eradicate – consciousness.
As an alternative, he asks a distinct query: Does the mind create consciousness, or might it’s shaping one thing extra basic?
Regardless of outstanding progress in understanding how the mind processes data, neuroscience nonetheless faces a profound thriller, Koch argues.
Scientists can increasingly identify the neural circuits involved in notion, reminiscence, emotion, and decision-making. But these discoveries nonetheless can’t clarify why bodily mind exercise is accompanied by subjective expertise.
As Koch writes in a brand new, as-yet unpublished essay shared with ScienceAlert: “Nothing in science explains how three kilos of matter, a chunk of furnishings of the Universe like every other, topics to the identical pure legal guidelines, can love, hate, dream, think about, concern or hope for its future.”
It is not the primary time Koch has grappled publicly with this puzzle. In 2023, he conceded a 25-year bet with thinker David Chalmers, admitting neuroscience was no nearer to pinning down consciousness’s neural mechanism than when he made the wager in 1998.
To handle that query, Koch turns to a philosophical framework generally known as analytic idealism, which proposes that consciousness could also be a basic characteristic of actuality slightly than one thing generated by the mind.
Inside this framework, the mind is considered much less as a producer of consciousness and extra as a filter or shaper of acutely aware expertise.
The concepts didn’t emerge from a single scientific experiment. As an alternative, Koch describes a deeply private expertise that essentially modified the way in which he thinks about consciousness and actuality.
A number of years in the past, whereas sitting alone on a seashore, he remembers the boundary between himself and the world dissolving, describing the expertise as a timeless and common actuality.
In his essay, Koch describes the expertise as “probably the most significant of my life,” writing that it “flipped my view of actuality”.
Koch is cautious to not current the expertise as scientific proof. As an alternative, he writes that it gave him “a view of Thoughts-at-Massive” and prompted him to re-examine the metaphysical assumptions that had guided a lot of his scientific profession, taking various philosophical views extra severely.
He additionally acknowledges that such experiences are inherently subjective. However he argues they shouldn’t be dismissed just because they’re tough to clarify, suggesting they, too, are a part of the phenomenon science is finally making an attempt to grasp.
Within the essay, he factors to developments in fashionable physics as one other reminder that a few of science’s deepest assumptions have already been revised. He doesn’t argue that quantum physics explains consciousness. Relatively, he means that the historical past of physics exhibits scientists have repeatedly been compelled to rethink the character of actuality when new proof emerged.
Koch argues that “our understanding of actuality should be rebuilt on a less complicated basis, suitable with each the ‘goal’ final result of empirical science in addition to with ‘subjective’ expertise.”
Koch argues that if present assumptions about consciousness show incomplete, neuroscience itself could finally require a equally profound conceptual shift.
The concepts even have implications for artificial intelligence. If consciousness will not be merely the product of more and more advanced computation, the trail towards acutely aware machines could also be extra sophisticated than merely constructing more and more highly effective AI methods.
That doesn’t imply future AI systems could never become conscious. Relatively, he argues that the talk can’t be settled just by making computer systems extra clever or extra computationally subtle.
Koch acknowledges that analytic idealism will not be a longtime scientific principle however a metaphysical framework whose future relies on whether or not its concepts may be translated into empirically testable hypotheses.

As he writes, “An important process for the long run is to take these insights and translate them into empirically testable hypotheses.”
He argues that consciousness stays one in all science’s biggest unsolved mysteries, and that understanding it could require researchers to rethink long-held assumptions in regards to the relationship between thoughts, mind, and actuality.
Koch’s work has been revealed in Nature Reviews Neuroscience.
