The brain might not create consciousness after all

Is consciousness something the brain produces, or is it woven into the fabric of reality itself? Renowned neuroscientist Christof Koch is challenging long-held scientific assumptions by confronting the “hard problem” of consciousness — why and how subjective experience exists at all. He highlights growing tensions between neuroscience, physics, and unexplained phenomena like near-death experiences and sudden moments of clarity before death.

Is consciousness simply created by the brain, or could it be a deeper feature of reality itself? That question is at the center of a presentation by Christof Koch, a leading figure in modern neuroscience, at the 15th "Behind and Beyond the Brain" Symposium organized by the Bial Foundation, taking place April 8 to 11 in Porto.

Can't wait to see how they plan on testing hypotheses and theories, or what might be new about this attempt at the saying the same thing others have been preaching for some time.
We might add a new flag in the sand?

Koch’s question is worth taking seriously, but “the brain might not create consciousness” covers several claims that would need different tests. Neural dependence is already strongly supported by lesions, anaesthesia and stimulation; that does not by itself decide whether the brain produces experience, filters a wider consciousness, or realises the local form of something fundamental. A useful discriminator would need a prediction on which those models diverge. For example, a filter model should specify information or structure that can be recovered when ordinary neural capacity is reduced and that cannot be explained by residual processing, reconstruction or prior knowledge. Without that, NDEs and terminal lucidity may motivate the hypothesis but do not yet separate it from brain-based accounts. So I share the question in the reply: what result would count against the “consciousness is fundamental” interpretation, rather than merely being compatible with it?

We cannot form a non-circular phenomenal description of what consciousness actually is, because any such description would necessarily presuppose the very experience it attempts to describe. Therefore, the fact that consciousness cannot be reduced to or captured by an objective description does not justify dismissing it as non-fundamental. On the contrary, our inability to describe its phenomenal nature independently leaves open the possibility that consciousness is itself fundamental. In simple terms - I don’t think we can imagine any result contradicting consciousness being fundamental. Still this doesn’t mean consciousness can exist independently of the underlying “hardware”.

On the last sentence, 'Still this doesn’t mean consciousness can exist independently of the underlying “hardware”', the word 'hardware' might at first glance appear to refer to something mundane; we know something is hardware because we can kick it or touch it. However it might be taken as a placeholder to substitute for something else, something incomprehensible or unimaginable in such mundane terms.

That helps clarify the point. I agree that an objective description cannot replace the phenomenal fact it is meant to explain. But if “consciousness is fundamental” is compatible with every possible result, then it is functioning as an ontological stance rather than a discriminating empirical hypothesis. That need not make it meaningless; it changes what evidence can establish.

More specific models built on that stance can still make different commitments. A filter or transmission model, a dual-aspect account and a physicalist realisation account may all accept neural dependence, but they need not predict the same recoverable information, causal structure or relationship between damage and experience.

I also agree with the qualification about hardware: fundamental consciousness would not automatically imply that local minds exist independently of organised systems. So my question was less “what observation disproves the metaphysics altogether?” than “what observation distinguishes this implementation from a physicalist realisation account?” If there is no such difference even in principle, the remaining disagreement may be metaphysical underdetermination rather than a scientific result.

“what observation disproves the metaphysics altogether?”

I have for some time wondered what finding might move the entire philosophy of mind to the next level - especially what would objectively disprove physicalism. I keep coming back to the same answer: only the unambiguous establishment of the paranormal, whether through veridical perception during an NDE or through some form of clairvoyance or telekinesis, would be decisive. And please note that an unexplained phenomena would not be enough - it must be established that the phenomena would not be possible with “natural” means, that is - it must be paranormal. Otherwise the physicalist would just move the goalpost.
