Shining light on spike timing-dependent plasticity

Abstract

Although spike timing-dependent plasticity has been well-characterized in vitro, it is less clear to what degree spike timing-dependent plasticity contributes to shaping visual system properties in vivo. In this issue of Neuron, two papers by Vislay-Meltzer et al. and Mu and Poo provide evidence that STDP contributes to the effects of sensory stimuli in refinement of the retinotectal system in Xenopus.
