How to Expand Your Consciousness | Dr. Christof Koch

About this video

Neuroscientist Dr. Christof Koch defines consciousness in terms of subjective experience: hearing, seeing, loving, hating, dreaming, and imagining, rather than merely responding to stimuli. Huberman introduces Dr. Koch’s work on perception, brain mechanisms, and how individual experiences and memories place each person in a unique perception box that shapes outlook, mental health, and physical health. Dr. Koch explains that this perception box can be changed through neuroplasticity. They discuss what flow states, psychedelics such as DMT, meditation, sleep, and dreaming reveal about the mind, as well as collective consciousness. In a later exchange, Huberman contrasts a live-and-let-live perception box with a moral-judgment one, and Dr. Koch introduces the Bayesian idea of a meta-prior as a possible way people might relate across differing assumptions.
