Significant main effect of condition on right and left amygdala activation as a whole, the BL subdivision of the left and right amygdala, and the AStr subdivision of the left amygdala (a) main effect of group on activation in the BL subdivision of the left amygdala (b), main effect of drug on activation in the BL and SF subdivision of the left and right amygdala (c), drug × group interaction on activation in the mPFC/rACC (d), and drug × group × condition interaction on activation in the AStr subdivision of the right amygdala (e). Stars indicate significant within- and between-group differences in corticolimbic activation. Error bars represent standard error of the mean.
