SCN pacemaker neuron
scn pacemaker neuron
A type of neuron located in the suprachiasmatic nucleus (SCN) that possesses intrinsic circadian rhythmicity, characterized by strong and rhythmic expression of core clock genes and the ability to independently generate and sustain circadian oscillations. In mice, the specific subtypes Avp+/Nms+, Vip+/Nms+, and Cck+/C1ql3+ neurons have the most robust circadian gene expression and contribute to synchronizing and maintaining rhythmicity within the SCN network (Wen et al., 2020).
