Fig. 1.

Whole-brain activation maps and parameter estimates for the three functionally-defined regions of interest (left and right amygdala, and subgenual anterior cingulate cortex, sgACC), and the comparison region, the right fusiform face area (FFA), for all runs (both days). Coloured arrows and stars indicate coordinates used in the analysis: cyan arrows correspond to peak activation in the left amygdala; green arrows to peak activation in the right; yellow arrows indicate the coordinate from a previous study (McKeeff and Tong, 2007) used for the FFA analysis; magenta arrows indicate peak activation in the sgACC. Images were thresholded at p<0.001 (uncorrected) and at the minimum cluster size surviving whole-brain cluster-level correction for each contrast; the heat bars indicate t-values. Please see Table 2 for statistics. A, E, I: faces vs fixation (1) and faces vs shapes (1) include all subjects; faces vs fixation (2) and faces vs shapes (2) (B, F, J) exclude the four subjects whose FFA was not included in the mask. Asterisk over the EM (*) bar chart depicts the only main or interaction effect of day or run: the effect of day on sgACC activation (p=0.045).
