Functional VS–IFG connectivity (PPI) during the High and Low Reward Happy conditions. Participants were conditioned to different levels of reward to two different neutral faces. Participants then viewed 4000 ms movie clips of the same two faces making happy facial expressions. A psychophysiological interaction analysis was performed with a physiological seed located in the right ventral striatum. The y-axis represents the mean z-stat relative to baseline for voxels inside the right IFG ROI. The error bars depict ±1 within-subjects standard error of mean (calculated using the method as described in Loftus and Masson (1994).
