REM Sleep
REM sleep is a stage of sleep associated with rapid eye movements, vivid dreaming, and high brain activity.
Overview
REM stands for rapid eye movement. During this sleep stage, the brain becomes highly active, dreams are often more vivid, and the body experiences muscle inhibition that helps prevent acting out dreams. REM sleep plays an important role in memory, emotional processing, and dream experience. It is one of the most studied phases of the sleep cycle.
Key Insight
REM sleep combines intense brain activity with physical immobility, making it central to vivid dreaming and dream-related phenomena.
Scientific Status
REM sleep is a well-established stage of sleep in neuroscience and sleep medicine.
How Researchers Study It
Researchers study REM sleep using polysomnography, EEG, eye movement tracking, laboratory awakenings, and dream reports.
