Question

Quizplus · Accepted Answer

REM sleep is characterized by rapid eye movement and vivid dreaming. While brain activity during REM sleep may be different than during wakefulness, it is not necessarily reduced, and there are no delta waves (which are associated with deep sleep). While some muscle contractions may occur during REM sleep, they are not the most characteristic feature.
