Ciliated neurons sited at the interface between the CNS and the cerebrospinal fluid (CSF) are present in many species; however, it is only in recent years that these ‘CSF-contacting neurons’ have been investigated in detail. Wyart et al. here discuss the features of these neurons and our current understanding of their varied contributions to CNS function.
