| Outline of Final Research Achievements |
In this study, we developed a novel experimental technique that enabled us to analyze anatomical and functional difference in the nigral dopamine neurons. First, we improved a pathway-selective expression system we recently developed to increase gene expression and decrease leak expression. Second, we refined a rabies virus vector we recently established to increase foreign gene expression, and created G-deleted vector. These improvement enable us to visualize the input-output pattern of nigral dopamine neurons. Moreover, using a viral vector expressing channelrhodopsin-2, we demonstrated that selective stimulation of the pathway from the frontal eye field to the superior colliculus affected neuronal activity. These results indicate that the viral vector systems created in this study can be used for analyzing anatomical and functional difference in the specific neuron groups such as nigral dopamine neurons.
