The nucleus accumbens (NAc or NAcc; also known as the accumbens nucleus, or formerly as the nucleus accumbens septi, Latin for ' nucleus adjacent to the septum ') is a region in the basal forebrain rostral to the preoptic area of the hypothalamus. [1] The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum.
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and other dopamine ...
Reviews of neuroimaging studies indicate that consistent aerobic exercise increases gray matter volume in nearly all regions of the brain, [31] with more pronounced increases occurring in brain regions associated with memory processing, cognitive control, motor function, and reward; [1] [5] [31] the most prominent gains in gray matter volume are seen in the prefrontal cortex, caudate nucleus ...
Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control. [1] Each pathway is a set of projection neurons, consisting of individual dopaminergic neurons.
The nucleus accumbens is located in the ventral striatum and integrates information from cortical and limbic brain structures to mediate behaviors the reinforce reward. [16] It is a major target for the dopaminergic projections from the VTA, a group of neurons located close to the midline on the floor of the midbrain .
cortex cingularis anterior. NeuroNames. 161. NeuroLex ID. birnlex_936. Anatomical terms of neuroanatomy. [edit on Wikidata] In the human brain, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33.
Basal forebrain. Part of the human brain, the basal forebrain structures are located in the forebrain to the front of and below the striatum. They include the ventral basal ganglia (including nucleus accumbens and ventral pallidum), nucleus basalis, diagonal band of Broca, substantia innominata, and the medial septal nucleus. These structures ...
The dorsal striatum is divided into the caudate and putamen by the internal capsule while the ventral striatum is composed of the nucleus accumbens and olfactory tubercle. [21] [22] The caudate has three primary regions of connectivity, with the head of the caudate demonstrating connectivity to the prefrontal cortex, cingulate cortex and amygdala.
