Figure 5

Comparison between the HC group and the LLD group. Top row: For each group, the lines represent the average and standard deviation of the PC1 and/or PC2 and the gray bar shows the \(-\log _{10} \text {(p-values)}\). A part of the fiber is considered significant, highlighted with red dots when the p-value is lower than the alpha value (\(5 \%\)) along a minimum cluster size which is estimated individually with the permutation test for each fiber. The PC is represented by the blue (PC1) and green (PC2) lines for the HC group and by the orange (PC1) and red (PC2) lines for the LLD group. Bottom row: Illustration of the 6 bundles corresponding to a HC subject. The red parts correspond to the significant areas of the bundles.
