Fig. 2.

ROI-based post hoc analysis of the brain regions with a significant interaction effect of group by post-outcome on the covariance between the risk level and the brain activation. A, left IFC; B, VMPFC; C, right ventral striatum; D, right inferior occipital gyrus/fusiform; E, right inferior temporal gyrus; F, left hippocampus/parahippocampus. The covariance between the risk level and the brain activation of these regions after loss significantly increased in IGD group compared with the HCs group.
