| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This study aimed to decompose the EEG activities related to the multimodal integration process. The participants were asked to respond to the location of the tactile stimulus presented at their index finger or thumb, while ignoring simultaneous visual stimuli presented at the same (congruent condition) or different (incongruent condition) finger. We found the significant increase of the congruent gamma band oscillation at the parietal area only, and the incongruent theta band oscillations at the anterior cingulate cortex (ACC). These results suggest that the multisensory process includes the binding process at the parietal cortex and the competition resolution process at the ACC. | |
