Figure 1.

Main effects of group in the group × facial emotion analysis of variance. Note: The conduct disorder (CD) group showed significantly lower activation than the healthy control (HC) group in medial orbitofrontal cortex (panel A; circled in blue), whereas the CD group showed increased right anterior insula activity relative to the HC group (panel C; circled in blue). Color bars represent F statistics. The images are thresholded at p<0.005, uncorrected, for display purposes. Plots of the data extracted from the medial orbitofrontal cortex and right anterior insula are displayed in panels B and D, respectively. These plots indicate that the main effects of group were independent of facial expression valence. Coordinates and statistics for the group effects are provided in Table 2.
