[Visual illusions evoked by rhythmic bursts and the "movement" through the cortex of waves of alpha activity].

In computer-controlled experiments the visual illusions were studied which appeared in human subjects under conditions of diffuse rhythmic photostimulation through the closed eyes with the individual dominant alpha-rhythm frequency. A significant correlation was demonstrated between the type of experienced illusion (or its absence) and the trajectory of the alpha-wave travelling in the prestimulation and stimulation periods.
