Electrical synapses determine the precise position of chemical synapses in the nervous system.

A cell surface receptor called Ret enables neurons to establish and maintain the organized arrays of dendrites that support communication between neurons.

Microtubule-microtubule sliding and neurite outgrowth in Drosophila is controlled by a Ser/Thr kinase Tricornered via phosphorylation of a 'mitotic' motor protein Pavarotti.
