Deskripsi
In gray matter, the relative contributions of myelinated axons and other tissue features to diffusion MRI (dMRI) are poorly understood. Here the authors combine ex vivo high-resolution dMRI of marmoset brain with histological sections of the same brain, and their findings suggest that in cortex, dMRI does not match the spatial distribution of myelin in the gray matter.
