| Abstract(in English) | The evoked brain activity during a mental hand rotation task is widely known related to motor imagery. Task-related activity during the task has been observed two brain areas, parietal and motor area. On the other hand, the relation to the functional brain activity between parietal and motor area is not well known. We then assumed that the two areas have the functional connectivity similar to that during a hand-choice task, and the mental hand rotation task was conducted in fourteen healthy subjects to investigate the evoked activity during motor imagery. In analysis, we mainly considered the effects in history of presented stimuli such as whether the stimulus is same (repeat trial) or different (switch trial) against previous trial. When we analyzed the functional connectivity based on phase synchronization, the parieto-motor connections were found during the task, and this connection had laterality-shift between right and left hemispheres in the switch trial. This suggests that the parietal area engaged to select the imagined hand. |
