The promise of fMRI in understanding reward processing. Shown here is an anterior view of a translucent cortical surface for the right hemisphere. Bilateral striatal surfaces are shown for the putamen (blue), NAcc (green), and caudate (red). Our synthesis of the literature suggests that fMRI holds promise for understanding individual differences and brain connectivity. In addition, multimodal approaches that combine fMRI with other tools, such as noninvasive brain stimulation, may reveal causal mechanisms that support reward processing. Brain surfaces were created with Chris Rorden's Surf Ice software.
