Outline of Research at the Start

本研究では、神経活動に伴い増減する血中因子に応答してMRI信号を増感する磁性ナノプローブを開発し、高感度全脳機能イメージング技術を確立することを目的とする。これにより、これまで見落とされていた神経活動パターンの発見につながるブレイクスルーを実現する。

Outline of Final Research Achievements

Imaging of neurotransmitters that correlate with signal transductions among neural cells is essential to reveal brain functions. Therefore imaging methods that make neurotransmitters in deep brain visible are required, although it remains challenging. Here we develop MRI contrast agents that produce MRI contrast changes responding to dopamine, serotonin, and glucose. These contrast agents could make it feasible to observe the neurotransmitters at whole brain levels.

Academic Significance and Societal Importance of the Research Achievements

本研究では、ドーパミンやセロトニンなどの神経伝達物質や、神経活動時に消費が増大するグルコースを検出するMRI造影剤の開発に成功した。これらの造影剤を用いることで、これまでの技術では困難であった脳深部における神経細胞の活動観察を、より詳細に行うことができる。つまり本研究は、感情、記憶、学習、認知などの脳機能の解明や中枢神経疾患の創薬研究を進展させる上で、極めて重要な役割を果たすと考えられる。
