fMRI data acquisition and Region-of-interest (ROI) analysis
We used a 3 T Siemens Trio scanner to record images and applied a T2* weighted reverse echo planar imaging (EPI) sequence for blood-oxygen-level-dependent (BOLD) functional images using an amygdala-sensitive sequence (for details, see Supplementary Materials and Methods). Images were preprocessed and analyzed using SPM8 (for details, see Supplementary Materials and Methods). Final analysis used a region-of-interest (ROI) approach. Anatomically-defined masks for the amygdala were created using the Talaraich atlas in the WFU PickAtlas tool [
