ventral striatum

Transclude of Frontal-Cortical-Changes-in-Cognition-in-Adolescence#^6d1793

The ventral striatum has been thus defined by the cortical projections from the medial prefrontal and orbitofrontal networks, the entorhinal cortex, and the projections from the amygdala and the hippocampus, all considered to be limbic brain areas involved in motivational and emotional processing

The brain “reward” system, centered on the limbic ventral striatum, plays a critical role in the response to pleasure and pain. The ventral striatum is activated in animal and human studies during anticipation of appetitive/pleasurable events, but its role in aversive/painful events is less clear.

This activation is observed during anticipation and is not a consequence of relief after the aversive event. Further, the ventral striatum is activated in anticipation regardless of whether there is an opportunity to avoid the aversive stimulus or not. Our data suggest that the ventral striatum, a crucial element of the brain “reward” system, is directly activated in anticipation of aversive stimuli.
