| Research Abstract |
We explored apparent motion illusion of beta movement by recording neuromagnetic responses of event-related fields (ERFs). A simple setting for visual stimulation of two stimuli was used, and the first stimulus (S1) was followed by the second (S2) with three conditions of stimulus-onset asynchrony, by which three different percepts of "seen-simultaneous", "optimal motion illusion," and "isolation" were obtained. Results were as follows; (a) The motion-related components showed large activation at around 100 msec after the S2 at the area of parietal. (b) That activation was transmitted for the temporal and frontal areas 300 msec later. Collectively, the percept of motion may be interpreted by both the object vision pathway and the spatial vision pathway.
