In order to investigate the genetic components of sleep and, in particular, of REM sleep, we performed 3 consecutive all-night EEG recordings in 26 pairs of normal male twins living apart (11 monozygotic and 15 dizygotic). Our results indicate that in man non-genetic rather than genetic influences substantially determine variance in stage REM, in contrast to stages 2, 4 and to delta sleep. In this sample of male twins, waking measures also showed a significant genetic component.

D012894 Sleep Stages Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; they formerly included Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep. In 2007, sleep stages were redefined by The American Academy of Sleep Medicine (AASM) as: N1-N2 (sleep onset - light sleep), N3 (SLOW-WAVE SLEEP), and REM SLEEP.
