Dorsal and ventral striatum definition
The dorsal striatum is the sensorimotorrelated part of the striatum and it is composed by the putamencaudate complex. Segmentation of striatal brain structures from high resolution pet images Interestingly, recent work (Corbit and Janak 2007) has also implicated the dorsal striatum.How can the answer be improved? dorsal and ventral striatum definition
Ventral definition is of or relating to the belly: abdominal. the ventral striatum, known as the brains reward center. Gretchen Reynolds being or located near, on, or toward the lower surface of an animal (as a quadruped) opposite the back or dorsal surface. b: being or located near, on, or toward the front or anterior part

The striatum is sometimes conceptualized as being divided into dorsal and ventral sections; the dorsal striatum contains the caudate and putamen, while the ventral striatum contains the nucleus accumbens.
As the dorsal (caudate nucleus and putamen) and ventral striatum (including the nucleus accumbens) constituted primary regionsofinterest (ROI), we performed an ROI analysis on BOLD signal in these areas, using the Marsbar toolbox (Brett et al.
Dorsal and ventral. These two terms, used in anatomy and embryology, refer to back (dorsal) and front or belly (ventral) of an organism. The dorsal (from Latin dorsum, meaning 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top.
Striatum is defined on the basis of its cortical connections, such that isocortex (neocortex) and allocortex (hippocampus and olfactory cortex) project to dorsal (caudate and putamen) and ventral striatum, respectively.
Dec 10, 2013 The striatum is composed of three nuclei: caudate, putamen, and ventral striatum. The latter contains the nucleus accumbens (NAcc). The caudate and putamenventral striatum are separated by the internal capsule, a white matter tract between brain cortex and brainstem.
Of the basal ganglia, the dorsal striatum (or caudate nucleus and putamen) is indicated in the figure solely by the label striatum ; part of the ventral striatum is represented by the nucleus accumbens; and the dorsal pallidum (that is to say, the globus pallidus) is shown.
Ventral Striatum: This area is a fairly small one that is inserted deep in the brain close to the basal ganglia. Until just recently, there has not been much known about the ventral striatum. But recently it has been associated with decision, risk and reward.
