The mature mammalian visual system is characterized by very precise and complex connectivity underlying the receptive field properties of visual neurons. During development, neuronal projections are often initially exuberant and only later are pruned to produce these precise connections. Neuronal activity is thought to play an important role in setting up the circuitry of the visual system, but what features of activity are necessary and how activity guides refinement of connectivity are open questions. © 2009 Elsevier Ltd All rights reserved.
