Dorsal raphe nucleus

Definition

A large raphe nucleus extending from the anterior part of the pons through the mesencephalon; its neurons are serotoninergic[NIF]. The dorsal raphe nucleus is a part of the raphe nucleus and consists of rostral and caudal subdivisions. The rostral aspect of the dorsal raphe is further divided into interfascicular, ventral, ventrolateral and dorsal subnuclei. The projections of the dorsal raphe have been found to vary topographically, and thus the subnuclei differ in their projections. An increased number of cells in the lateral aspects of the dorsal raphe is characteristic of humans and other primates. [WP,unvetted].

Also known as cell group b7, dorsal nucleus of the raphe, dorsal nucleus raphe, dorsal raphe, inferior raphe nucleus, nucleus raphes dorsalis, nucleus raphes posterior, posterior raphe nucleus — per UBERON

The Dorsal raphe nucleus is a part of the Nervous.
