Research Abstract

The role of alteration of electrophysiological properties of neurons on the formation of neuronal network remains to be elucidated. Using cerebellar granule cells, I demonstrated the processe of dendritic maturation and the mechanisms of activity-dependent up-regulation of maturation genes.
