A9 cell group (A9)

The term A9 cell group refers to the most densely packed group of cells fluorescent for dopamine in the ventrolateral midbrain of rodents ( Dahlstrom-1964 ) and primates ( Felten-1983 ). It is for the most part identical with the pars compacta of the substantia nigra as defined on the basis of Nissl stains.

Also known as: A9 cell group, dopaminergic group A9

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.
