Figure 11.

Heatmap describing the influence of the ROIs of the right brain on the significance of the interaction effect between AGE and ASD diagnosis (${\beta }_{\mathrm{AGE}\times \mathrm{ASD}}$) in Equation (6). The more negative is the value (the effect of the ith ROI in the Granger causality as $t_{\mathrm{AGE}\times \mathrm{ASD}}-t_{\mathrm{AGE}\times \mathrm{ASD}}^{-i}$), the greater is the ROI’s influence. Notice that the pars opercularis and superior parietal gyrus are the ROIs that contribute the most to AGE × ASD.
