Significats de ventral striatum en anglès

Dopamine input to the dorsal and ventral striatum originates from separate populations of midbrain neurons.

In the bipolar disorder subjects, depressive symptoms correlated positively with signal increases in the ventral striatum.

In turn, lower ventral striatum gray matter volumes were associated with lower reward dependence, a prosocial trait.

Adolescents recruited greatest bilateral ventral striatum during reflected social self-evaluations, which was positively correlated with age and pubertal development.

We suggest that the neural substrates that may subserve these impairments include the ventral striatum, amygdala, and prefrontal cortices.

We found that CU traits were associated with greater activation of the ventral striatum (VST) during reward anticipation.

In the ultra-high-risk sample overall, at follow-up, symptomatic improvement and reduced rCBF in the hippocampus and ventral striatum were observed.

The relationship of pain complaints and activation in the periaqueductal gray and ventral striatum depended on the T-allele of rs563649.

However, unique to this study was a significant three-way interaction between age group, evaluative perspective, and domain within bilateral ventral striatum.

These results demonstrate an open cortico-basal ganglia loop whereby limbic information could modulate motor output through ventral striatum control of M1.

When shifting to a set that required attention to a novel cue, rats with ventral striatum lesions made more perseverative errors.

Results indicated activity in ventral striatum preceded risky decisions and activity in right inferior frontal gyrus (rIFG) preceded safe decisions.

In the dilemma situation, functional connectivity between prefrontal brain regions and the ventral striatum was significantly diminished in the risk allele carriers.

Significant signal change in the region of the ventral striatum was also observed on such reversal errors, from a region of interest analysis.

Furthermore, functional connectivity between the ventral striatum and prefrontal areas exerting top-down control on the mesolimbic reward system was reduced in this group.

Longitudinal increases in adolescents' ventral striatum activation mediates the link between greater parental depression and increases in adolescents' risk taking and externalizing behavior.
