Sub-Regions of The Dorsal Raph é Nuleus Receive Different Inputs From The Brainstem
The dorsal raphe nucleus (DRN) through its extensive efferent projections has been implicated in a great variety of physiological and behavioral functions including the regulation of the sleep-wake cycle. This nucleus is composed of 5 sub-regions defined according to the distribution of its serotonergic (5-HT) neurons. In addition to its heterogeneity in neuronal populations, the DRN contains a great diversity of 5-HT neuronal subtypes identified based on their electrophysiological characteristics, morphology and sub-regional distribution.
