| Abstract: | Continuous light exposure can suppress circadian rhythms. In this issue of Neuron, Murad et al. demonstrate that, under certain genetic conditions, a novel cluster of pacemaker neurons can drive rhythmic behavior in constant light. Surprisingly, these neurons are distinct from those thought to drive rhythms in constant darkness. |
