Figure 1.

(A/B) Shown here on the FreeSurfer average brain surface are adjacent regions of right posterior insula/temporal operculum in which cortical thickness was correlated with conditioned fear during acquisition in the cognitive regulation (A) and extinction (B) experiments (cluster maximum of P < 0.001, uncorrected, minimum vertex inclusion threshold P < 0.01, uncorrected). (C) Scatter plot depicting the relationship between the mean cortical thickness of the region shown in (A) and the skin conductance measure of conditioned fear during acquisition in the cognitive regulation experiment. (D) Scatter plot depicting the relationship between the mean cortical thickness of the region shown in (B) and the skin conductance measure of conditioned fear during acquisition in the extinction experiment.
