Illustration of SPM maps demonstrating the significant positive regression (p<.05) between greater FHD and greater activation during the Interference condition of the Stroop task [Interference – Word Reading]. Local maxima coordinates were x=6, y=37, z=11, with 75 activated voxels, SPM {t} = 5.49, significant at small volume corrected threshold, p<.05, and containing right ACC (BA32). L, left hemisphere; R, right hemisphere. Red circles represent individuals subjects and black diamonds represent average activation for each FHD group.
