B9 cell group
Acronym: 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 ).
