Christof Koch Challenges 30-Year Brain Theory, Casting Consciousness as Fundamental Reality

Summary
At an April 2026 symposium in Porto, Christof Koch argued consciousness may be a fundamental feature of reality, with the brain shaping or filtering it rather than producing it.
The Allen Institute scientist says 30 years of neuroscience have mapped neural correlates but still not solved David Chalmers' 1995 “hard problem” of why subjective experience exists at all.
Koch ties that challenge to Integrated Information Theory, which quantifies consciousness through phi, while citing gaps in current frameworks including near-death reports from about 10% of resuscitated cardiac-arrest patients.
A 2023 adversarial test with 256 subjects found both IIT and Global Neuronal Workspace Theory partly right and partly wrong, reinforcing the theoretical deadlock behind Koch's shift.
The proposal remains an unpublished, unreviewed essay, leaving its biggest hurdle unchanged: turning a metaphysical claim into testable scientific hypotheses.
With AI models developing hidden internal workspaces, could artificial systems be tapping into the same fundamental consciousness that neuroscientists are struggling to explain?
If consciousness is truly a fundamental force of reality, are modern scientific methods completely flawed for trying to locate it inside biological brain tissue?
If the human brain merely filters a universal consciousness rather than creating it, what exactly happens to our awareness when the biological filter dies?
