Non-REM (NREM) sleep uses significantly less energy than REM sleep. ... NREM sleep is divided into three separate sub-stages: N1, N2 and N3 or slow-wave sleep. Each of these stages can last from 5 to 15 minutes or more and NREM stages may repeat until REM sleep is attained.
What happens in NREM sleep?
NREM sleep: NREM (non-rapid eye movement) sleep is dreamless sleep. During NREM, the brain waves on the electroencephalographic (EEG) recording are typically slow and of high voltage, the breathing and heart rate are slow and regular, the blood pressure is low, and the sleeper is relatively still.
What are the functions of NREM and REM sleep?
REM sleep is the major source of dreams, whereas synchronous cortical oscillations, called slow waves, are observed during NREM sleep. Both stages are unique to certain vertebrate species, and therefore, REM and NREM sleep are thought to be involved in higher-order brain functions.
