B4 cell group - BrainInfo

B4 cell group (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 ).

Also known as: B4 serotonin cells, serotonergic group B4, B4 cell group

Models Where It Appears

Monoamine Cell Groups

are collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain one of the neurotransmitters serotonin, dopamine, norepinephrine ( Fuxe-1970 ) or epinephrine ( Kitahama-1994 ). They are classified respectively as serotonergic cell groups, dopaminergic cell groups, noradrenergic cell groups and adrenergic cell groups.
