The table displays BP_ND decreases in the rewarded relative to the nonrewarded condition. BP_ND reductions in the individual anatomical voxels of interest from the PMOD analysis (means ± SEs) and statistical results from the MarsBaR-based analysis of the normalized ROIs in SPM2 are shown. *The result in the left NAcc remained significant at p < 0.05 after Bonferroni correction for the number of ROIs.
