Figure 2

Gray matter volume differences between groups, overlaid onto average T1 image from study. Slice numbers (relative to AC-PC origin plane) are shown in upper left corner for each slice. Relative increases (autism > control) are shown in red-orange color scale corresponding to upper right color bar and relative decreases (control > autism) are shown in blue-violet color scale corresponding to lower right color bar. The display threshold is p < .01, uncorrected, but only clusters surviving small volume correction, p < .05, are illustrated (see Table 1 for coordinates and label descriptions).
