The Ventral Stratium is positivly corrlated with effort, and thus it is sought to be involved in motivation[1], and also the rACC[2][3]
The neural circuitry of reward ‘wanting’ versus reward ‘liking’. The neural circuitry of reward ‘wanting’ comprises the ventral striatum (VS; blue), while that for reward ‘liking’ comprises the vmPFC, including the orbitofrontal cortex (OFC) and the dorsal and ventral anterior cingulate cortex (dACC, vACC) (green), which closely interacts with the amygdala (AMY = orange) and the midbrain, including the ventral tegmental area (VTA; purple). This complex network interfaces with motor-related areas and other higher cognitive associative cortices (not shown here) to translate basic reward information into appropriate goal-directed action plans to achieve a desired reward[4].
The ventral striatum fulfilled all three criteria and therefore qualified as a common motivational node capable of driving both cognitive and motor regions of the dorsal striatum[5].
A need for action may be modulated by dopamine[6]
