Which human brain activity is most associated with REM sleep?
Quick Answer
REM sleep is the stage most associated with vivid dreaming and brain activity patterns similar to wakefulness. It usually appears several times a night in cycles.
The Full Story
REM, or rapid eye movement, sleep is the sleep stage most closely linked to vivid dreaming. During REM, the brain shows high activity, while most skeletal muscles are temporarily paralyzed to prevent acting out dreams. REM episodes become longer later in the night and recur in cycles roughly every 90 minutes. This stage is thought to support memory, emotion processing, and learning. Its distinctive pattern was first identified in the 1950s.
