Statistical parametric maps (SPMs) showing brain areas, which are activated by aversive facial expressions relative to neutral faces, as reflected by an increase in BOLD signal. The SPMs are color coded in yellow and red indicating increases in activity, and are thresholded at p<0.001 (uncorrected). The upper left panel gives the activation maps for the contrast aversive faces > neutral faces (A). The middle and lower panel on the left display the activation maps for the two facial emotions separately. Angry faces > neutral faces (B); fearful faces > neutral faces (C). The bar graphs presented in the right panel give statistical estimates (arbitrary units) of face related activity levels in the amygdala and fusiform gyrus for the control session (left column) and ketanserin session (right column) (D). The parameter estimates are taken from the regional maxima showing the strongest increase in regional activity for aversive faces relative to neutral faces. The error bars represent the 90% confidence intervals of the mean.
