WebbDescent into stage II non-REM sleep is characterized by 10–15 Hz oscillations (50–150 μV) called spindles, which occur periodically and last for a few seconds. Stage III non-REM sleep is characterized by slower waves at 2–4 Hz (100–150 μV). Stage IV sleep is defined by slow waves (also called delta waves) at 0.5–2 Hz (100–200 μV). Webb9 mars 2024 · However, during deep sleep (N3 of non-rapid eye movement sleep, i.e. slow wave sleep), the cortical down state may last as long as 500 ms. 1 Moreover, the down state may last even longer (several seconds) under anaesthesia, 1 when a person is arguably even ‘less conscious’ than in slow wave sleep, as attested to by a subjective …
