REM sleep plays a crucial role in emotional recovery, with studies showing that 60% of participants experience REM rebound after deprivation. Historical discoveries by pioneers like Aserinsky and Kleitman established its unique characteristics, including a blend of brain activation and muscle atonia. The review emphasizes REM sleep homeostasis and its periodicity within ultradian rhythms. It also explores the complex relationship between arousals, sleep, and consciousness, highlighting notable distinctions between non-REM and REM sleep-related arousals, revealing their similarities to wakefulness.
