Memories are made of this ?? – (Part 2)

Thomas McHugh from the RIKEN Center for Brain Science continues his discussion about memories, emotions, the brain, and life.

Strong emotions plus non-REM sleep equals longer-lasting perceptual memories

Perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep, specifically during periods of deep non-REM sleep.
