INTRODUCTION
The purpose of this study is to investigate the effects of sleep deprivation on individual attentional function and related electrophysiological mechanisms.
METHODS
Twenty healthy men who were deprived of sleep for 24 h were evaluated by selective attention test, persistent attention test, and event-related potentials (ERP) experiment.
RESULTS
After 24 h of sleep deprivation, the subjects' selective attention decreased, mainly manifested as prolonged response time, decreased motion stability, increased rate of neglect error, decreased sustained attention, prolonged latency of P300 at Cz (=0.001), and decreased amplitude (=0.000).
CONCLUSION
After 24 h of sleep deprivation, the attentional ability decreased significantly, and behavioral and ERP indicators showed certain changes.
引言
本研究旨在探讨睡眠剥夺对个体注意力功能及相关电生理机制的影响。
方法
对20名被剥夺24小时睡眠的健康男性进行选择性注意力测试、持续性注意力测试及事件相关电位（ERP）实验评估。
结果
睡眠剥夺24小时后，受试者的选择性注意力下降，主要表现为反应时间延长、动作稳定性降低、疏忽错误率增加、持续性注意力下降、Cz点P300潜伏期延长（=0.001）以及波幅降低（=0.000）。
结论
睡眠剥夺24小时后，注意力能力显著下降，行为和ERP指标均出现一定变化。
