Where Does Consciousness Come from? Two Neuroscience Theories Go Head-to-Head

Neuroscientists are still debating the origin of consciousness in the brain. A major study compared two leading theories: integrated information theory (IIT) and global neuronal workspace theory (GNWT). The study, involving 256 participants across 12 labs, found neither theory's predictions were fully supported by brain imaging data. This inconclusive result has sparked further discussion and research in the field. Understanding consciousness has important practical applications, such as assessing awareness in coma patients or during anesthesia.
