desynchronized sleep
Alternative term for REM sleep, referring to the desynchronized brain wave patterns observed during this stage.
Full Definition
Desynchronized sleep is a clinical term for REM sleep that emphasizes the characteristic brain wave patterns seen on electroencephalography. Unlike the synchronized, high-amplitude waves of deep sleep, REM sleep shows low-amplitude, mixed-frequency activity resembling wakefulness. This desynchronization is accompanied by vivid dreaming, temporary muscle paralysis, and rapid eye movements. The term is commonly used in sleep study reports and clinical documentation.
Usage
Usage note: Use 'REM sleep' in patient communications; 'desynchronized sleep' is appropriate for technical reports.
