Fig. 3.

Brain regions that showed a significant Group (positive mood induction vs neutral mood induction) × Value (reward vs loss) interaction during the anticipation period. The positive mood induction group showed greater activity than the neutral mood induction group during reward anticipation in the left ventromedial prefrontal cortex (VMPFC), left nucleus accumbens (NAc), right caudate, left putamen, left lateral orbitofrontal cortex (OFC), and left anterior insula. The positive mood induction group, in contrast, showed reduced or equivalent activity than the neutral mood induction group during loss anticipation. Note: error bars represent standard error of the mean (SEM).
