Abstract

An experiment using 6 Macaca mulatta monkeys was conducted to determine the physiological and behavioral changes concomitant with 176 hours of sleep deprivation. The physiological changes were observed by recording EEG and cortical brain temperature continuously throughout 5 days of baseline, 8 days of deprivation and 8 days of recovery. Primarily behavioral changes were observed by performance on a delayed matched-to-sample task during which the Ss worked for food pellets. The rhesus has a definite stage 4 and PS recovery which was apparently critical in counteracting the stress of sleep deprivation. Further a stage 2 recovery was observed that had been previously overlooked and appeared to be closely connected with the after-effects of sleep deprivation, specifically the relief of fatigue. The 24 hours cycle based on cortical temperature showed a disruption during deprivation and the return of this 24 hour cycle did not correspond with the EEG or behavioral recovery data. There was some evidence that the performance on a delayed matched-to-sample task for food could continue unchanged through 8 days of sleep deprivation. The important behavioral finding was not one of consistent impairment, but one of wide individual tolerance to sleep loss. For the first time, complete rather than partial sleep recovery was observed and there was evidence that survival and capability to work are linked to specific sleep stages
