Apparent motion was used as a probe to test the hypothesis that perceptual framing is correlated to the phase of the alpha rythm. Stimuli were presented phasically with respect to the occipital and parietal alpha cycle, and subjects were asked to judge whether the stimuli appeared simultaneus or sequential. The probability of perceived simultaneity was maximal for the positive phase of the occipital alpha cycle. Visual evoked potentials recorded during stimulus presentation were significantly different, in the late components, for the cases of perceived simultaneity or sequential motion. A brief review of previous experimental and theoretical studies of the relationship of perceptual framing to alpha rythm is presented.
