Non-rapid eye movement (NREM) sleep is the first type of sleep entered after falling asleep and comprises approximately 75-90% of total sleep time in healthy adults. The AASM divides NREM sleep into three stages (N1, N2, N3).

Growth hormone is released, tissue repair occurs, and the glymphatic system clears metabolic waste from the brain. EOG: No eye movements. EMG: Low muscle tone. 5. Stage R (REM Sleep) eeg and sleep physiology ppt
Disappearance of the alpha rhythm, replaced by low-amplitude, mixed-frequency (LAMF) activity, predominantly in the theta band (4–7 Hz).

Four distinct wave graphics side-by-side, showing the shape difference (from fast/spiky to slow/rolling). Bullet Points:
: This stage hosts vivid dreaming and emotional memory consolidation. EOG: No eye movements
Disorders of partial arousal. NREM parasomnias (e.g., sleepwalking, night terrors) occur when a patient becomes trapped in a hybrid state between Stage N3 deep sleep and wakefulness. REM Sleep Behavior Disorder (RBD) occurs when the muscle atonia pathologically fails, allowing patients to physically act out violent dreams.
). To score a page as N3, these slow waves must occupy at least 20% of the 30-second epoch.
