Seed-based fiber tractography. The white matter regions of the lesion behavior map of general cognitive ability/working memory (g/Gwm) were segmented into clusters and then each cluster was submitted as a seed region-of-interest in a deterministic fiber tractography analysis. This analysis produced voxel-wise maps indicating the number of white matter streamlines passing through each voxel that originated from the seed region-of-interest. The tractography maps were summed into a single map (depicted in a red-yellow palette, where more yellow colors indicate a higher number of streamlines), thresholded at 200 streamlines, and compared with the Human Connectome Project White Matter Atlas. There was a prominent involvement of the arcuate fasciculus (light blue).
