Differentiation of neuronal dendrites

Proper neuronal function is strongly dependent on its morphology. One key part of this is the correct development of dendritic arbors. In this project we utilize the dendritic arborization neurons found in the larvae of Drosophila melanogaster as a tool to investigate the dynamics of a developing dendrite and the mechanisms steering the establishment of proper dendritic morphology.
