Anatomical terms of neuroanatomy

The dorsal raphe nucleus is one of the raphe nuclei. It is situated in the brainstem at the midline. It has 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.[1]
