ventral striatum

[TA]
those portions of the striatum located generally inferior to a plane representing the anterior commissure; includes the nucleus accumbens and some nuclei of the olfactory tubercle; may function in motor activities with emotional or motivational origins.
Synonym(s): striatum ventrale [TA]

ventral striatum

The nucleus accumbens plus the olfactory tubercle at the base of the cerebral hemisphere. These regions are part of the limbic circuitry.

The reinforcing properties of habit-causing drugs are associated with the activation of the mesolimbic dopaminergic pathways such as prefrontal cortex, ventral striatum and ventral tegmental area.
Dr Voon and colleagues also found that the younger the patient, the greater the level of activity in the ventral striatum in response to pornography.
As the dorsal (caudate nucleus and putamen) and ventral striatum (including the nucleus accumbens) constituted primary regions-of-interest (ROI), we performed an ROI analysis on BOLD signal in these areas, using the Marsbar toolbox (Brett et al.
Alcoholic patients showed greater activity in the ventromedial prefrontal cortex, the ventral striatum, insula, and specific regions of the thalamus and cerebellum during the neutral-relaxing condition (Sinha 2007; Sinha and Li 2007).
In scans performed before the medication regimen, smoking cues activated brain areas involved in drug-motivation, such as the ventral striatum and medial orbitofrontal cortex, and also elicited reports of craving.
When the youngsters (10 to 13-years-olds) were scanned to measure blood flow through their brains, while looking at faces showing a range of emotions, scientists found increased activity in a tiny structure, the ventral striatum, deep in the brain.
In this study, we aim to overcome this limitation and develop an algorithm capable of separating the striatum into four structures (caudate, putamen, ventral striatum, and white matter) [3].
More importantly, this ventral striatum response occurred even when no decisions were made, suggesting that the calculation of social standing--as indexed by payment--may be automatic (Fliessbach et al.
approaching environmental stimuli associated with reward), which is largely mediated by the ventral striatum (nucleus accumbens) and the associated cortico-basal ganglia circuit (Corbit et al.
Dopamine stimulates the ventral striatum and nucleus accumbens, the parts of the brain that process rewards and create positive emotions like satisfaction and enjoyment.
