B9 cell group - BrainInfo

B9 cell group (B9)

The term B9 cell group refers to a group of cells fluorescent for serotonin that is located in the pontine tegmentum, ventral to the B8 cell group. In the human they are found predominantly in the median raphe nucleus with some scattered laterally into the paramedian raphe nucleus ( Hornung-2012 ). In the macaque they are found in the ventral part of the median raphe nucleus and adjacent structures ( Felten-1983 ). In the rat ( Paxinos-2009b ) and the mouse ( Franklin-2008 ) they are distributed horizontally dorsal to and within the medial lemniscus of the pons ( Dahlstrom-1964 ).

Also known as: B9 serotonin cells, serotonergic B9 field, serotonergic group B9, group B9, B9 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.
