| Outline of Final Research Achievements |
Physiology of an axon and its terminals in the central nervous system remains elusive because of the difficulty to analyze the small size of structures. In this project, we clarified the dynamic regulation mechanism of information processing in the axon and terminals by using the direct patch-clamp recording technique together with local activation of transmitter by a spot laser illumination method. Specifically, we analyzed dynamic regulation mechanisms to control transmitter release from terminals of Purkinje cells and granule cells which mediate fine motor control.
