Figure 5.

Effect of preprocessing model on ROI-ROI correlations and group differences. Correlation matrices for the TD and ASD groups and the corresponding group comparisons are shown for each of the four preprocessing models using 1880 ROIs sampled from the group brain mask. Results for the “Basic” model (Motion+Ventricles+Local WM) are shown in the upper left, the Basic+GCOR model in the upper right, the Basic+GS regression model in the lower left, and the full ANATICOR model in the lower right. The upper two plots of each model show the average ROI-ROI correlation matrices for the TD and ASD groups (see corresponding colorbars for scale), the lower left plot of each model shows the unthresholded t-values, and the lower right plot of each model shows the t-values thresholded at p < 0.05 (uncorrected). ROIs are ordered by scanner coordinates (ranked by Inferior-Superior, then by Anterior-Posterior, then by Right-Left).
