Right hemisphere — Impact of 5-HTTLPR on posterior–anterior default network connectivity differs in youth with ASD compared to controls. Voxels in color indicate places where genotype influenced connectivity between that area and the posterior hub differently for the ASD group and the control group. A significant genotype-by-diagnosis interaction in the anterior default network (xyz = 44, 56, − 6, t₁₁₆ = 4.17, p = 0.027, corrected for multiple comparisons within bilateral BA 10) is depicted in the sagittal section of the brain (upper), with the threshold set at p < 0.01 for illustration purposes. To depict the interaction, contrast values from a 4 mm sphere around the peak voxel (xyz = 44, 56, − 6) were extracted and plotted (lower).
