(A) Whole-brain voxel-wise statistical F-map displayed on a canonical brain showing group differences in activation for fearful versus neutral faces as a function of perceptual load (low vs. high) localized to the anterior cingulate cortex (peak voxel at 0, 30, 6, F=12.2). (B) Bar graphs depicting extracted parameter estimates of activation from the ACC ROI within each group showing gSAD exhibited positive ACC activation to fearful versus neutral faces under high but not low perceptual load, whereas HC showed the opposite pattern.
