| Outline of Final Research Achievements |
To understand how the frontal lobe and related areas of the brain work to enable the brain to cope with multitasking. Several types of tasks were learned by monkeys, and then they were made to perform the tasks under different conditions. Cell activity and local electric field potentials were recorded during execution. Cells were found to encode two strategies for multitasking. One was a dynamic encoding in which the information represented by a single cell changed as the task progressed, with each cell playing multiple roles. The other was a group of cells that responded differently to different task conditions, with different groups of cells selectively participating in each context. The results suggest that phase synchronization between multiple oscillations is important in multitasking, linking regions broadly at the oscillation level and selecting cells that participate in phase synchronization.

マルチタスクは、細胞が一人多役を時間的に情報変化しながら対応している場合と、それぞれのタスクに特異的に活動する細胞を準備して行う場合がわかった。また振動により、多数の領域が位相同期することで、参加細胞を選択する機構も判明してきた。マルチタスクには、２つの方法はトレードオフがあると考えられる。日常生活にもしばしば起こる。このマルチタスクを支えるの神経機構を理解することはマルチタスクができない認知的な障害がある人の理解やリハビリに示唆を与えると考えられる。
