Figure 5.

A, MDS plot, based on cross-correlation analyses of individual sulcal depth maps, for all 58 WS and control left and right hemispheres. Each dot represents an individual hemisphere, grouped according to the color scheme indicated by the lettering in the panel. Crosses indicate the group means for the correspondingly colored group. Arrows denote exemplar cases used in the analyses shown in Figures 6 and 7, including one from each group biased toward the control side (blue arrows), one from each group biased toward the WS side (yellow arrows), and one from each group that was intermediate (black arrows). The distributions were similar for the age-matched WS subgroup (18–30 years) and the age-outlier subgroups. Likewise, the distributions for men and women were similar within the WS group and within the control group. B, Map of left versus right asymmetry for control (top), all 16 WS subjects (bottom left), and the 12 right-handed WS subjects (bottom right) using t-statistic maps thresholded at t > 3.
