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.

摘要

持续光照会抑制昼夜节律。在本期《神经元》杂志中，穆拉德等人证明，在某些基因条件下，一组新的起搏器神经元能在持续光照下驱动节律行为。令人惊讶的是，这些神经元与那些被认为在持续黑暗中驱动节律的神经元不同。
