Effects of Prolonged Stage Four and 1-Rem Sleep Deprivation: Eeg, Task Performance, and Psychologic Responses

摘要

Two experiments are described which demonstrated the effects of extended stage 4 sleep deprivation and separately the effects of 1-REM sleep deprivation. Measurements of the sleep EEG and measurements of personality variables revealed that these two types of sleep deprivation are quite different. Stage 4 deprivation resulted in a sharp increase in stage 2 on deprivation nights while 1-REM deprivation resulted in an increase in stage 1 without rapid eye movements. Stage 4 deprivation produced a depressive psychologic profile in the subjects while 1-REM deprivation resulted in a state of increased irritability and emotional lability.
