title: Sawtooth waves: concomitants of rapid eye movement sleep in monkeys.
abstract: Sawtooth waves, 2--3 c/sec activity of at least 40 micro V, occurred primarily during clusters of REMs in stump-tailed macaques. On the average the activity began well after the onset of REMs but occasionally occurred soon before or immediately after a cluster of REMs. The activity was clearly defined but occupied less than 0.6% of an 8-h sleep record. A sawtooth burst was, on the average, 7.5 sec in duration.
