REM Phase Density

Meaning

REM Phase Density is a measure quantifying the concentration and intensity of physiological events, such as rapid eye movements, muscle atonia, and characteristic brain wave activity, within the Rapid Eye Movement (REM) stage of sleep. This metric reflects the robustness and quality of the REM sleep periods, which are vital for emotional regulation, procedural memory consolidation, and neural reorganization. A higher density suggests a more consolidated and functionally effective REM sleep experience. Disruption of this density can impact cognitive and psychological well-being.
