Association between resting CBF values and DIT-N2 Scores. Resting CBF values in (A) ventral striatum and (B) ventromedial prefrontal region were positively correlated with DIT-2 N2 scores. The functional ventral striatum (VS) ROI and the ventromedial prefrontal ROI were defined based on the CBF results. Independent ROI analyses revealed similar results that (C) VS and (D) ventromedial prefrontal regions were positively correlated with DIT-2 N2 scores. The independent VS ROI and ventromedial prefrontal ROI were defined based on previous literature24. Openness and Neuroticism were controlled in the partial correlation analyses.
