Abstract :
Response of the alpha wave to flicker stimuli is investigated with temporally alternating red/blue flicker stimuli. Entrainment phenomenon of the alpha wave is enhanced in comparison with that to single-color stimuli; either a quasi-phase-locking or a clear phase reversal is observed over the scalp. The result is useful for considering the underlying mechanism of hyper-synchronization of brain waves such as the photosensitive epilepsy.
