Dependence of spatiotemporal response of alpha wave on light intensity of repetitive photic stimuli

Dependence of spatiotemporal response of brain alpha wave on the light intensity of flicker stimuli is studied. In spite of inter-individual differences in the spontaneous alpha waves, most of the alpha waves are destabilized when the intensity of stimuli applied is low, while they are stabilized with increasing the intensity of the stimuli. The result may be useful for modeling a nonlinear dynamics of the alpha wave.
