What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. In this BIT, Koch argues that consciousness is a fundamental property of networked entities, and rhapsodizes about integrated information theory—how it explains many puzzling facts about consciousness and provides a blueprint for building sentient machines.
