Abstract:
Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.
