Research Abstract

Electroencephalography (EEG) has been considered as reflecting selective consciousness and recognition activity level. Cortical activation patterns based on the maximum entropy method (MEM) were more distinct than those based on the fast Fourier transform (FFT) and these results depended on well-defined peaks in MEM power spectral density (PSD).
As far as color perception was concernd, red and green light stimulation did not produce any differences in general on the basis of the topographic analysis of EEG spectral power computed by the MEM.
The effect of vigilant task workloads at simulated accidents in a nuclear power plant control room was also investigated on the basis of EEG with the MEM.The results suggested that the most experienced leader at his works easily could return to the state of being ready for a next possible trouble right after an accident was brought under control, but less experienced leader kept on maintaining the same high activity state as in the midist of an accident after settling down the accident. The MEM-PSD analysis could be a breakthrough in finding indivisual differences more precisely against various stressful complex situations.
