The 25-Year Bet: Neuroscientist and Philosopher Settle Debate on Consciousness

Neuroscientist Christof Koch loses a 25-year bet with philosopher David Chalmers about discovering a signature of consciousness within the brain. Koch had hoped to find activity in specific neurons related to conscious experience but failed to do so. Alternative theories on consciousness, such as the integrated information theory (IIT) and global network workspace theory (GNWT), were also found to be imperfect matches to the data. Both theories will require revision.
