| Abstract(in English) | Binocular rivalry is a phenomenon in which the perception alternates when two dissimilar images are independently presented to two eyes. Although a lot of previous studies on this phenomenon have done, it is still not revealed on the issue of when and where rivalry occurs in the brain. In this study, we used competitive moving stimuli in which six stripes drifting to opposite or the same directions in order to investigate the brain activities when subjects observed the competitive or its control cooperative stimuli drifting same direction. We measured EEGs and analyzed event-related potentials (ERPs) and event-related synchronizations(ERSs)/desynchronizations(ERDs) for competitive and cooperative stimuli triggered by the change of the direction of optokinetic nystagmus. As a result, significant differences in ERSs/ERDs at alpha band (8-13Hz) were observed in the frontal and parietal regions, particularly in the right hemisphere, at 500～300ms before perceptual alternation. |
