摘要

Purpose

To clarify the relationship between electroencephalograms (EEGs) and video-identified behavioral signs of microsleep.

Methods

EEGs during each behavior were evaluated using two maintenance of wakefulness test (MWT) cases with whole-body video monitoring.

Results

In MWTs, 30.3% and 60.5% of the behavioral signs of microsleep corresponded to alpha waves and microsleep, respectively. We demonstrated that EEG frequency decelerated during behavioral signs of microsleep compared to that while awake. Slow eye movements on the electrooculogram preceded or coincided with behavioral signs of microsleep corresponding to EEG microsleep.

Conclusions

EEG frequency deceleration could be inferred from behavioral assessments based on whole-body video monitoring.
