Learning events are "replayed" at rapid speed during deep sleep to reinforce learning | Matt Walker

Parent Episode: Dr. Matthew Walker on Sleep for Enhancing Learning, Creativity, Immunity, and Glymphatic System

Events experienced during periods of wakefulness trigger the activity of different neurons in the brain. During sleep, the brain "relives" those events by triggering the activity of the same neurons – at 10 to 20 times the original speed. This process, known as long-term potentiation, stabilizes memories by serving as a pruning mechanism, selectively strengthening strongly associated memories and weakening weakly associated ones. In this clip, Dr. Matthew Walker describes how studies in rats and humans demonstrate that the brain "replays" events and experiences to facilitate learning.
