Figure 1. Reward-based decision-making.

Decision-making relies on a converging network of cortical and subcortical regions. For simplicity, arrows are not drawn to indicate laterality of connections. Blue areas: reward valuation seems to primarily involve the ventral striatum, ventromedial prefrontal cortex (vmPFC), orbitofrontal cortex (OFC), and posterior cingulate cortex (PCC). Red areas: the amygdala, insula, and anterior cingulate cortex (ACC) are involved in processing uncertainty and emotional inputs into choice. Green areas: the dorsolateral cortex (dlPFC) and posterior parietal cortex (PPC) are involved in executive control and choice selection.
