Abstract
Numerous recent electroencephalographic studies have revealed the cyclical alternation of two distinct types of sleep (Dement and Kleitman, 1957a), which have been termed “fore-brain” and “hind-brain” sleep by Jouvet (1962). The former is accompanied by slow waves and spindles in the electroencephalogram (EEG) and the latter by a low-voltage, fairly fast EEG pattern; spasmodic, conjugate rapid eye movements (REMs); relaxation of neck and throat muscles in cat (Jouvet, 1962) and human (Berger, 1961); and recall of dreams following awakening (Dement and Kleitman, 1957b).
