WebbSlow-wave sleep usually comprises 25% of the night in younger adults but almost 0% in the elderly. REM sleep is characterized by low-voltage, high-frequency EEG with minimal or no muscle tone and with rapid eye movements. REM sleep, which is also called dream sleep, comprises 20–25% of the night. WebbSleep stages are characterized by spectral content of EEG: for instance, stage N1 refers to the transition of the brain from alpha waves (common in the awake state) to theta waves, whereas stage N3 (deep or slow-wave sleep) is characterized by the presence of delta waves. The normal order of sleep stages is N1 → N2 → N3 → N2 → REM. in country summary
