| Outline of Final Research Achievements |
The purpose of this study was to clarify neural processing of visual attention, including sustained and transient manners, based on neurotransmitter concentration in the brain. With further research, a comparative experiment of visual and auditory attention was added to the objectives of this study.
We measured neurotransmitter concentrations and brain activities during conducting sustained visual attention tasks with visual or auditory stimuli. The results showed that the same brain area was engaged in both visual- and auditory-sustained attention. We also found that different neurotransmitters contributed to carrying sustained and transient visual attention.

| Academic Significance and Societal Importance of the Research Achievements |
視覚情報に注意を向け続ける場合、それに関わる神経伝達物質は、注意を向ける視覚情報を切り替える機能に関わる神経伝達物質とは異なる一方で、聴覚情報に注意を向け続ける機能に関わる神経伝達物質とは同じであることを、世界で初めて明らかにした。このことは、一過性の注意と持続性の注意ではそれぞれの脳処理が異なっているが、それぞれの処理では視聴覚情報が分け隔てられていないという、これまでにない新しい注意の脳メカニズムを考えなければならないことを意味している。
