Neurotransmitter regulation of neuronal outgrowth, plasticity and survival.


Molecules used for communication in mature nervous systems also play important roles in development, maintenance and plasticity of individual neurons. This paper reviews the evidence that neurotransmitters, in addition to their mediation of trans-synaptic information coding, can induce a spectrum of effects on neuronal cytoarchitecture, ranging from neurite sprouting to dendritic pruning and even cell death. Such profound alterations may well constitute a part of the normal functioning and structuring of the nervous system as well as contribute to severe pathological processes.
