WebFeb 13, 2024 · REM sleep (stage R): theta waves or wave-like patterns The onset of sleep begins with wakefulness and progresses rapidly to REM sleep by approximately 60 to 90 minutes. [2] [6] This is followed by cyclical alterations between REM and NREM every 90 to 120 minutes until awakening. WebA characteristic component of REM sleep is an unstructured pattern of low amplitude (4–7 Hz) mixed frequency neurological activity, as measured by electroencephalography. The neurological activity during REM sleep displays sawtooth wave forms or trains of sharp triangular waves that occur at 2–6 Hz.
