Of pride and groom: The gains and limits of studying the neuroanatomy of rodent self-grooming in translational research
Résumé
In this issue of Neuron, Xie et al. characterize a cell-specific premotor circuit, generating rhythmic orofacial forelimb movements. The authors show that neurons of the caudal part of spinal trigeminal nucleus, expressing Cerebellin-2, are necessary and sufficient for triggering forelimb movements, which form a part of rodent self-grooming.
