White-matter tract atlas

Our tract atlas was annotated manually using diffusion MRI data from the MGH Connectom scanner, collected as part of the young adult Human Connectome Project. The following images show 42 tracts and average microstructural measures along each tract (FA: fractional anisotropy; RD: radial diffusivity; AD: axial diffusivity).
