Responses evoked by safe and threat fearful faces. Left: ROI results. Bar plots of response magnitude as a function of safe/threat and easy/hard conditions. Significant differences were observed during easy trials but not during hard trials leading to significant or near-significant statistical interactions. Right: Voxel-wise contrast between threat and safe fearful faces during the easy letter-detection task. Abbreviations: ACC, anterior cingulate cortex; FG: fusiform gyrus; MFG: middle frontal gyrus; SPL, superior parietal lobule; L: left; R: right; Int: interaction; ns: not significant. Error bars are standard error of the mean.
