A8 cell group (A8)

The term A8 cell group refers to a small group of cells fluorescent for dopamine in the human ( Halliday-2012 ), macaque ( Felten-1983 ), rat ( Dahlstrom-1964 ) and mouse ( Franklin-2008 ). It is located in the midbrain reticular formation dorsolateral to the substantia nigra at the level of the red nucleus and caudally. It overlaps the classically defined retrorubral area and, in the human, the midbrain reticular field ( Halliday-2012 ).

Also known as: A8 cell group, dopaminergic group A8, A8 dopamine cells, lateral midbrain reticular formation A8 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.
