Figure 2.

Psychophysiological interaction (PPI) parameter estimates for each task between the seed regions and the dorsomedial frontal/cingulate (DMFC) cortex region of interest. Data marked with “x” (as opposed to those marked with a filled circle) indicate runs that were not significantly different from zero (and therefore were not analysed further). Horizontal lines in the box plots indicate the mean (darkest line), standard deviation, and 95% confidence interval. A: Emotion identification (EI) task; B: Face matching (FM) task (not analysed further, as the average PPI parameter estimates were not significantly different from zero); C: Gender classification (GC) task (the subgenual anterior cingulate cortex (sgACC) seed was not analysed further, as the average PPI parameter estimate was not significantly different from zero). ROI: region of interest; LAmyg: left amygdala; RAmyg: right amygdala.
