Dopaminergic cell groups are collections of neurons in the central nervous system that have been demonstrated by fluorescence to contain the neurotransmitter dopamine.
Eleven discrete dopaminergic cell groups have been identified.
Group A8 is a small group of dopaminergic cells in rodents and primates. It is located in the midbrain reticular formation dorsolateral to the substantia nigra at the level of the red nucleus and caudally. In the mouse it is identified with the retrorubral field as defined by classical stains.
Group A9 is the most densely packed group of dopaminergic cells, and is located in the ventrolateral midbrain of rodents and primates. It is for the most part identical with the pars compacta of the substantia nigra as defined on the basis of Nissl stains.
Group A10 is the largest group of dopaminergic cells in the ventral midbrain tegmentum of rodents and primates. The cells are located for the most part in the ventral tegmental area, the linear nucleus and, in primates, the part of central gray of the midbrain located between the left and right oculomotor nuclear complexes.
Group A11 is a small group of dopaminergic cells located in the posterior periventricular nucleus and the intermediate periventricular nucleus of the hypothalamus in the macaque. In the rat, small numbers of cells assigned to this group are also found in the posterior nucleus of hypothalamus, the supramammillary area and the reuniens nucleus.
