Exploratory whole brain analyses of the interaction between race and HF-HRV revealed a negative correlation for African Americans only between resting HF-HRV and perfusion in a cluster of voxels centered in the left ventromedial prefrontal cortex (BA 10). This cluster also extended into the ventral (BA 24) and dorsal anterior cingulate (BA 32). MNI coordinates of peak activity: x = −12, y = 38, z = −14; cluster size = 12,717mm3; Z value of peak activity = 3.529; FWE corrected cluster p value = .02. Blue crosshairs are centered at the voxel of peak activity.
