Digital human brain white matter (WM) atlases play an important role in brain imaging research. Existing WM atlases have been generated either based on anatomical landmarks, thus mixing tracts with substantially different roles, or using DTI tractography, which fails in regions with crossing fibers. The purpose of this study was to develop a probabilistic WM atlas of the adult human brain by performing probabilistic tractography on an artifact-free high angular resolution diffusion imaging (HARDI) brain template constructed in ICBM-152 space. Presented preliminary results show that the information contained in the new atlas is in agreement with known anatomy.
