Differential Extinction recall on Day 2 of the experiment was calculated by subtracting mean SCR for the first four CS+NE from first four CS+E acquired during the extinction recall phase. The lower the SCR the better the recall magnitude. See detailed explanation in Section 3.1. (A) PTSD: There were significant differences between men and women t30 = 2.42, p < 0.03. TE-HC: No significant differences were found between men and women t24 = −0.43, p > 0.67. Error bars denote standard errors of mean. (B) PTSD: Voxel-wise activation within the left rostrodorsal anterior cingulate cortex (rdACC) ROI was increased for CS+E compared to CS+NE specifically in men. Regions of activation shown are significant to p < 0.05, the uncorrected voxel-wise threshold was used for visualization of spatial activation within the dACC and it does not correspond to the statistical test performed to determine significance. (C) PTSD: Mean SCR contrast values for CS+E vs. CS+NE within the entire left rdACC ROI.
