Research Abstract |
An enormous number of homotypic and heterotypic inputs innervate given neurons, and establish functional neural circuits through their competition. In this study, I undertook cellular and molecular mechanisms underlying the competitive circuit development in the cerebellum, a center of motor learning and coordination. I have identified that glutamate receptor GluD2 on Purkinje cells and Cbln1 released from granule cells coordinately regulate the formation and maintenance of parallel fiber synapses, and the establishment and maintenance of climbing fiber mono-innervation.
