Auditory Evoked Potentials as a Function of Sleep Deprivation and Recovery Sleep
Abstract
Four questions were addressed by the present research: They related to the effects of: a) 48-hours of sleep deprivation on endogenous event related potentials (ERPs); b) circadian rhythms on ERP recordings; c) different durations of recovery sleep (1,2,4 hours) on ERPs. A central question asked was: Can ERP changes associated with sleep loss predict the performances changes associated with sleep loss? i.e. can changes in ERP recordings be used to predict performance degradation associated with sleep loss? Forty male subjects (30 deprived of 48-hours of sleep, 10 control (nondeprived) subjects were participants. Every four hours (12 four-hour blocks) subjects were tested on performance batteries including the PAB) and had ERPs recorded (P1, N1, P2, N2, P3). The major findings of the study were: decreases in amplitude for N2, P3 and N2P3 across the reprivation period; a circadian rhythm was apparent for both ERP recordings and performance; performance degradation on virtually all tasks was apparent across the 48-hour deprivation period; naps of 1-hour were not restorative but may be counterproductive as indexed by ERP amplitudes and performance measures; naps of 2 and 4 hours were only partially restorative; a high correlation obtained between performance and ERPs across the 12 four-hour blocks; a high correlation obtained with in a block between ERP values and performance; N2 may be a better predictor of performance that P3. The results suggest overall that certain ERP measures may be useful in identifying sleepiness/alertness and in predicting performance levels.
