Matt Walker: Sleep | Lex Fridman Podcast #210
Lex Fridman
Matt Walker, a sleep scientist and professor at Berkeley, shares his journey from accidentally becoming a researcher to fundamentally redefining why we sleep. His fascination began with states of consciousness like anesthesia during medical school in the UK, leading him to investigate dementia by recording brainwaves while patients slept rather than awake. This shift revealed that sleep disruption might be a cause, not just a symptom, of cognitive decline.…
