Table 1. Summary of literature.
Studies that have compared orientation estimates from dMRI in post-mortem brain tissue to independent measurements of axonal orientations from a reference modality. We list the reference modality, type of tissue, and dMRI acquisition parameters for each study (“iso” indicates isotropic voxels).
