Differences between men and women in psychophysiological and BOLD measures during extinction memory recall. A. Skin conductance responses (SCR) averaged across the first 4 extinction recall trials for the extinguished stimulus (CS + E) compared to the unextinguished stimulus (CS + U). B. BOLD activation to the CS + E vs. CS + U contrasting Females vs. Males during extinction recall are shown. C. Mean beta weights extracted from the left and right rostral ACC and insula are shown, to illustrate the direction of activation within group. The threshold for the maps in B is p < 0.01, uncorrected. M = males; F = females.
