Supplementary analysis for comprehending the hypothesis-free results indicate that pilots and controls exhibit differential network-based organization. Post-hoc FC analysis with the resulting cluster from the intrinsic connectivity contrast (ICC) analysis as seed region. (A) Results from the comparison of pilots versus controls. Significant decreases are shown in magenta and are scaled by t-value (p < 0.005 uncorrected at the voxel-level, p < 0.05 family-wise error corrected at the cluster-level). The plot illustrates the average effect size of the FC between left inferior frontal gyrus (IFG) and the medial superior frontal gyrus (SFG) for pilots and controls (error bars indicate 95% confidence intervals). (B) Associated network of the left IFG illustrated by the positive and negative correlations with the rest of the brain in red-yellow and blue-purple respectively (p < 0.001 uncorrected at the voxel-level, p < 0.05 family-wise error corrected at the cluster-level). Results are scaled by t-value. R = right, L = left.
