Starting from the case report of photosensitivity epilepsy, PSE when audience were watching on a TV program that broadcast high contrast blue red blinking, a large number of studies about photosensitivity were done in such a way as to analysis of EEG behavior.As a result,high contrast blue red blinking stimulation has the frequency of about 10 Hz that elicit PSE and photo-paroxysmal response,PPR was confirmed. On the other hand, the frequency of the alpha waves that give the effect of relaxation exist in this band too. Therefore,the analysis of EEG were evoked by blinking stimulation of about 10 Hz that is necessary for understanding the influence on audience were exerted blinking stimulation has effect of relaxation. This study analyzed EEG behavior was evoked by blinking stimulation have the frequency was changed from 1 up to 9.5Hz. In the result the increase in EEG activity level in frontal area and two stratification tendency in the power spectrum were observed. This paper is a consideration of that.
