A novel atlas of the superficial white matter connectivity based on the whole HCP cohort - an inter-individual variability study.

Superficial white matter (SWM) tracts exhibit a high cross-subject variability, which makes them difficult to study. We used the whole HCP cohort, which included 1065 subjects, to build a comprehensive atlas of the short-range cortico-cortical connections using an advanced diffusion analysis and tractography pipeline, followed by an individual and a group-level fiber clustering. Furthermore, we measured the percentage of occurrence of each cluster within the population. In addition to enabling the automatic labeling of any new subject’s SWM tracts, our atlas paves the way for a thorough cross-subject variability study of superficial connectivity.
