| Research Abstract |
To understand the neural mechanisms of the rehabilitation for the improvement of the prefrontal functions, we analyzed brain activity using magnetoencephalography during a visuospatial working memory task. The results showed :(1) the increase of alpha activity in the parietal-occipital sensors was observed during the delay period not only in the visuospatial working memory task but also in the control task without any working memory demand,(2) the increase of alpha activity was suppressed by visuospatial distractors. These results indicate that alpha activity is not related to the maintenance of information in working memory processing but may reflect the disengagement from visuospatial attention. Thus, the present research revealed the contribution of alpha activity in the parietal-occipital area during the visuospatial working memory task.
