Reward processing and the striatum. A: a large-scale meta-analysis of 506 neuroimaging studies indicates a selective association between the term “reward” and striatal activation (Yarkoni et al. 2011). These observations help illustrate the reliability of neuroimaging evidence in demonstrating the involvement of the striatum in reward processing. B: anatomical subdivisions of the striatum in the human brain. These subdivisions include the putamen (blue), NAcc (green), and caudate (red).
