Amygdala and vmPFC regions of interest (ROIs).

(A) Amygdala subregions examined in the present study were selected from FSL’s Juelich histological atlas (Eikhoff et al., 2007) and thresholded at fifty percent; each voxel was assigned to only one subregion. The subregions included the centromedial amygdala (CM; red) and the basolateral amygdala (BL; blue). The superficial amygdala was not included, consistent with previous studies (Jalbrzikowski et al., 2017). (B) The ventromedial prefrontal cortex (vmPFC) subregions used in the present study were derived from Mackey and Petrides (2014), implemented in AFNI and converted to MNI space. The subregions included the ventral anterior cingulate cortex (ACC; orange), the rostral ACC (purple), the anterior vmPFC (yellow), and the subgenual cingulate (green) (for interpretation of the references to color in this figure legend, the reader is referred to the web version of this article).
