Figure 1 shows the results of ST analysis in a region with in-plane fiber crossings. We find that, in both MRI and histology, the percent of voxels with crossing fibers actually increases as we increase the resolution. The
middle and bottom rows highlight “single” fiber regions in red and “crossing” fibers as green, and qualitatively
show that many regions with a “single” fiber population at a coarse resolution exhibit crossing patterns when
processed at a finer resolution.
