title: Fear of the light or need for action: the IGL will judge.
abstract: Temporal adaptation of behaviors is of crucial importance for every organism. In this issue of Neuron, while elegantly establishing the developmental program of the subcortical visual shell (SVS), a group of retinorecipient nuclei, Delogu et al. (2012) also implicate one of its structures, the IGL, as a potential important player in the regulation of daily activity pattern.
