S3 E38 - What Your Brain Does While You Sleep
S3 E38 - What Your Brain Does While You Sleep
A sleeping brain is not an inactive brain. Jack and Janet use the image of a city at three in the morning to explore the hidden work of sleep: changing electrical rhythms, coordinated blood-flow and cerebrospinal-fluid patterns, and the still-evolving science of the glymphatic system. They explain what researchers have learned from animal studies, what human studies suggest about amyloid-beta and tau, and why the strongest conclusions require restraint. This episode replaces the familiar idea of sleep as “doing nothing” with a more accurate one: sleep is a distinct biological state with important consequences for memory, function, and long-term brain health.
