Silence sets on a sensory map

Neuron. 2004 May 27;42(4):521-2. doi: 10.1016/j.neuron.2004.05.006.

Abstract

Recent efforts to understand the contribution of neuronal activity in the creation of the olfactory sensory map have focused on odor-evoked events. In this issue of Neuron, Yu et al. discover a new role for neuronal activity in the organization and maintenance of the olfactory system. Their results highlight the role of spontaneous activity and synaptic transmission in axon outgrowth and olfactory neuron survival.
