Abstract: | The differential effect of either one night's total sleep deprivation (TSD) or of selective REM deprivation (REMD) was examined on post-deprivation daytime EEG patterns with respect to control, in the same group of rhesus monkeys. TSD resulted in significantly decreased wakefulness and increased amounts of NREM and REM on the first day following TSD. In contrast, highly significant REM elevation without alteration of other EEG states occurred for 3 days after REMD. Post-deprivation behavioural and photic-induced neural changes were minor. The results obtained after sleep deprivation in simians are comparable with similar findings in human subjects. |
