Diffusion MRI is a powerful tool to investigate the structural connectivity of the brain and to characterize its microstructure. In this study, we propose to adapt the white matter bundles clustering approach - previously achieved on humans - to the mouse in order to establish the foundations of a novel atlas of the structural connectivity. To this aim, 3D High Angular Resolution Diffusion Imaging (HARDI) was performed ex vivo on C57Bl6 mice brains (100µm isotropic) at 9.4T and clusters of fibers were computed using an automated procedure across the entire brain.
