| Abstract(in English) | The purpose of the present study was to investigate the brain regions underlying audio-visual temporal order judgments using functional magnetic resonance imaging (functional MRI). Twenty healthy volunteers were asked to judge whether visual and auditory stimuli were presented synchronously or not in an MRI scanner. As the result, the frontal and parietal cortex, cerebellum and thalamus were significantly activated during audio-visual sjnichronization task. In addition, the temporo-parietal junction and premotor cortex were significantly activated only when subjects judged that the two media were not synchronized. Therefore, activity in these brain regions might be useful to estimate subjective judgments in audio-visual synchronization task. |
