A4 cell group - BrainInfo

A4 cell group (A4)

The term A4 cell group refers to a group of cells exhibiting noradrenergic fluorescence that, in the rat, are located in the Tegmen ventriculi quarti (roof of the fourth ventricle) ventral to the cerebellar nuclei ( Dahlstrom-1964 ) and in the macaque are found at the edge of the lateral recess of the fourth ventricle caudally, extending to beneath the floor of the ventricle where they merge with the noradrenergic group A6, the locus ceruleus ( Felten-1983 ).

Also known as: A4 cell group, noradrenergic group A4

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.
