A13 cell group (A13)

The term A13 cell group refers to a group of cells fluorescent for dopamine and distributed in clusters that, in the primate, are ventral and medial to the mammillothalamic tract of the hypothalamus; a few extend into the reuniens nucleus of the thalamus ( Felten-1983 ). In the mouse A13 is located ventral to the mammillothalamic tract of the thalamus in the zona incerta ( Paxinos-2001 ). Functionally it belongs to the reticular formation (functional) of the brainstem motor system ( Swanson-2004 ).

Also known as: dopaminergic group A13, A13 cell group, A13 dopamine cells, zona incerta, dopaminergic 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.

Functional CNS Model - Rat

The Functional CNS Model - Rat (FMrat) ( Swanson-2004) is one of three hierarchical models representing the internal organization of the central nervous system (CNS). The others are the Structural CNS Model - Human (SThmn) and the Functional CNS Model - Human (FMhmn). The FMrat model represents the basic organization of the mouse ( Hof-2000 AMBA-2024 ) and, presumably, other rodents. Functional CNS models differ from structural models in that structures are defined and named by connectivity rather than by proximity to other structures at the same level. Functional models are more useful for representing longitudinal components of are grouped based on information drawn from multiple neuroscientific disciplines. such as connections, neurochemical characteristics, and role in physiogical and behavioral processes. While the Functional Model was developed primarily for an atlas of the rat brain ( Swanson-2004 ), the hierarchical organization of structures is for the most part applicable to the human, macaque, mouse and other mammalian brains as well. Structures at lower levels of the Functional CNS hierarchy are largely the same as in the Classical and Developmental Models, i.e., they were originally identified by stains for gray matter (Nissl substance) and white matter (myelin). At the next higher level they are grouped into basic connectional and functional systems of the CNS, such as the subcortical sensory systems, the brainstem motor system and the behavioral state system. At the highest levels CNS structures are grouped on the basis of dissection and embryologic precursors into cerebrum ( cerebral cortex and cerebral nuclei ), cerebellum, and cerebrospinal trunk.
