| Abstract(in English) | Mental manipulation of working memory is associated with the brain synchronization between frontal regions for the executive function and each sensory region. However, it is not clear about whether the synchronization is associated with manipulation or maintenance. Here, we recorded EEG data during performing auditory and visual WM tasks and compared the theta synchronizations when subjects performed either auditory or visual manipulations in separate WM tasks, or performed both two manipulations in the same WM task. The time-frequency EEG analyses revealed significant fronto-temporal theta phase synchronization during auditory manipulation in both auditory and auditory/visual WM tasks, but not during visual manipulation tasks. In contrast, the significant fronto-parietal theta phase synchronization was observed during visual manipulation tasks, but not during auditory manipulation tasks. Moreover, we observed significant synchronization in both the fronto-temporal and fronto-parietal theta signals during simultaneous auditory/visual manipulations. These findings suggest the importance of theta synchronization in manipulation but not in maintenance of WM. |
