Diffusion MRI Anisotropy in the Cerebral Cortex is Determined by Unmyelinated Tissue Features

Published: Sep 2, 2021
Abstract
The diffusion of water molecules through the brain is constrained by tissue and cellular substructure, which imposes an anisotropy that can be measured through diffusion magnetic resonance imaging (dMRI). In the white matter, myelinated axons strongly shape diffusion anisotropy; however, in gray matter the determinants of dMRI signals remain poorly understood. Here we investigated the histological tissue properties underlying dMRI anisotropy and...
