MeSH Heading: Ventral Tegmental Area
Tree Number(s): A08.186.211.132.659.413.875.820
Unique ID: D017557
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D017557
Scope Note: A region in the MESENCEPHALON which is dorsomedial to the SUBSTANTIA NIGRA and ventral to the RED NUCLEUS. The mesocortical and mesolimbic dopaminergic systems originate here, including an important projection to the NUCLEUS ACCUMBENS. Overactivity of the cells in this area has been suspected to contribute to the positive symptoms of SCHIZOPHRENIA.
