| Research Abstract |
We have measured multi-channel bio-signals, i. e., electroencephalogram, heart rate variability, blood pressure, eye movement and pupil diameter variability in order to evaluate the influence of visual stimuli to the wakefulness maintenance state against sleepiness. We performed time-frequency analysis, conventional spectral analysis, and feedback modeling to those signals. All results showed that physiological activities in wakefulness maintenance state have different features from those in onset of natural sleep. In addition, we have introduced new artifact removal methods to the EEG analysis.
