B4 cell group
Acronym: B4
The term B4 cell group refers to a few cells fluorescent for serotonin located in the floor of the fourth ventricle, in the vicinity of the vestibular nuclei and abducens nucleus in the rat ( Dahlstrom-1964 ) and in the caudal interstitial nucleus of the medial longitudinal fasciculus of the mouse ( Paxinos-2001 ). A comprehensive study of monoaminergic cell groups in the macaque and the squirrel monkey did not identify a B4 cell group distinct from other groups in the region ( Felten-1983 ).
