The associations, adjusted for translocator protein rs6971 genotype (high-affinity binders [HAB] or mixed-affinity binders [MAB]), are shown for the dorsolateral prefrontal cortex (DLPFC: r = 0.6; P = .03) (A) and the medial prefrontal cortex (mPFC: r = 0.6; P = .04) (B). Similar correlations were present in the temporal cortex (r = 0.6; P = .03), anterior cingulate cortex (r = 0.5; P = .05), cerebellum (r = 0.6; P = .02), and gray matter as a whole (r = 0.6; P = .03).
