Electrophysiological Mechanism of Attention of Sleep Deprivation: Evidence From Event-Related Potentials (ERP) Data.

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 ( p =0.001), and decreased amplitude ( p =0.000).
Conclusion: After 24 h of sleep deprivation, the attentional ability decreased significantly, and behavioral and ERP indicators showed certain changes.
Competing Interests: The authors have declared that no competing interests exist.
