During development, the nervous system is confronted with a problem of enormous complexity; to progress from a large number of 'disconnected' neurons to a network of neuronal circuitry that is able to dynamically process sensory information and generate an appropriate output. To form these circuits, growing axons must make synapses with targets, usually the dendrites of postsynaptic neurons. Although a significant amount is known about the signals that regulate and guide developing axons, we are only now starting to understand how environmental cues like growth factors and activity regulate the formation and maintenance of dendrites in the developing and mature nervous system.
