Outline of Final Research Achievements

Dopamine neuron is main neuron in central nervous system and mainly located in ventral tegmental area. The fluctuation of ventral tegmental area dopamine neuronal activity was measured when acute noxious stimuli were given. We utilized a fiber photometry system which has high time resolution by calcium imaging system. We measured specific dopamine neuronal activity using DAT-Cre mice by Cre-loxP system. Fluorescence intensity of G-CaMP6, green fluorescence protein, was analyzed as measurement index. Various stimuli resulted in a rapid increase in the activity of VTA dopamine neuron. We published the paper and presented these findings at a conference.

Academic Significance and Societal Importance of the Research Achievements

我々は、急性の嫌悪刺激が急速に意識清明のマウスの腹側被蓋野におけるドーパミン神経活動を上昇させることを測定結果から明らかにした。測定に非常に高い時間分解能を有しているファイバーフォトメトリーを使用しており、腹側被蓋野のドーパミン神経活動と疼痛や精神疾患への治療方法を関連させて検討する所見として有用である。明確に瞬間的な神経活動を評価できる点でもファイバーフォトメトリーが非常に有用なツールであることを示すものである。
