A12 cell group (A12)

The term A12 cell group refers to a small group of cells fluorescent for dopamine in the arcuate nucleus of the hypothalamus in primates ( Felten-1983 ). In the rat a few cells belonging to this group are also seen in the anteroventral portion of the paraventricular nucleus of the hypothalamus ( Dahlstrom-1964 ).

Also known as: A12 dopamine cells, dopaminergic group A12, A12 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.
