It should be noted that the regions of the ventral cognitive circuit also interact with the other neurocircuits and play a role in their functions. For instance, the STN is involved in the control of emotional and motivational behaviors via its connections with fronto-limbic and ventral affective circuits, respectively [128]. The IFG participates along with regions of the dorsal cognitive circuit to form a network that mediates working memory [129]. Thus, targeting the ventral cognitive circuit for response inhibition impairments in OCD, discussed next, is likely to affect the function of other neurocircuits.
