Spatial phase response of the alpha wave is investigated under the condition that red and blue flicker stimuli are temporally alternately applied. The alternating stimuli lead to two distinct phase distributions depending on the subjects: 1) a phase reversal, in which the phases of the alpha waves are antilocked between the occipital and frontal regions, and 2) a quasi-phase-locking, in which the phase difference distribution includes the temporal alternation of a phase locking over the entire scalp and the phase reversal between the occiput and front. The result suggests possibilities for the underlying mechanism of the hyper-synchronization of the brain waves seen in photosensitive epilepsy.
