Research News and Information
Definition of 'Nucleus Accumbens'Collection of pleomorphic cells in the caudal part of the anterior horn of the lateral ventricle, in the region of the olfactory tubercle, lying between the head of the caudate nucleus and the anterior perforated substance. It is part of the so-called ventral striatum, a composite structure considered part of the basal ganglia. Common names: Nucleus Accumbens; Accumbens, Nucleus |

Corticosteroid receptor modulation of mesoaccumbens dopamine neurotransmission is believed to be a key neurobiological mechanism mediating the effects of stress in addiction. Importantly, nucleus accumbens (NAc) subregions (core and shell) are ... Read more...
Altered corticostriatal functional connectivity in obsessive-compulsive disorder.
30 Oct 2009 CONTEXT: Neurobiological models of obsessive-compulsive disorder (OCD) emphasize disturbances in the function and connectivity of brain corticostriatal networks, or "loops." Although neuroimaging studies of patients have supported this network model ... Read more...
29 Sep 2009 Substantial evidence suggests that pharmacological manipulations of neural serotonin pathways influence ingestive behaviors. Despite the known role of the nucleus accumbens in directing appetitive and consummatory behavior, there has been little ... Read more...
