Apathy relationship captures by the PC1 and PC2 over 5 bundles. Top line: The lines represent the average and standard deviation of PC1 (blue) and PC2 (orange) and the gray bar shows the \(-\log _{10} \text {(p-values)}\)). The significant fiber areas estimated in the correlation analysis using PCs are highlighted with red dots. Bottom row: Illustration of the 5 bundles corresponding to a HC subject. The red parts correspond to the significant areas of the bundles.
