  1. Tested relationships between NAcc-MPFC circuit connectivity and cognitive, affective, and clinical measures within patients are shown. As described above, correlational analyses were Bonferroni corrected for a total of 6 independent comparisons and determined to be significant at the level of p < 0.008 (corrected threshold).
