Identification of U-Bundles Based on Sulcus Morphology

摘要

We presented preliminary results from the short bundle identification across groups with different central sulcus morphology. These results show that some bundles present different configurations which might drive or come from differences in the sulcus shape. Notice that sometimes, for groups in the extreme of the isomap axis some bundles are not present. Although these bundles might have been discarded during the filtering steps performed, it is interesting as it might be as well because of smaller or even nonexistent connections that impact the shape of the corresponding gyri. However, a better strategy needs to be found in order to ensure that bundles less reproducible within a group could survive until the matching step, as these bundles might present the transition between the two groups. Although these results are preliminary, it shows that there is a link between the brain wiring and the cortical folding pattern. Future work will be focused on testing these differences on a bigger dataset (HCP dataset [8]). This would also allow dealing with more groups which might lead to a smoother transition across the isomap axis.
