REM Sleep Biology

Meaning

REM Sleep Biology refers to the distinct physiological and neurobiological processes that precisely characterize the Rapid Eye Movement (REM) stage of sleep, which cycles throughout the nocturnal period. This critical stage is physiologically marked by brain activity closely resembling the waking state, profound muscle atonia, characteristic rapid eye movements, and vivid, narrative dreaming. REM sleep is absolutely critical for emotional regulation, comprehensive memory consolidation, and high-level, adaptive cognitive function.
