Fig. 3: Four underlying cortical microstructural factors stratify cytoarchitectural classes, laminar differentiation and functional networks.
From: Mapping the microstructure of human cerebral cortex in vivo with diffusion MRI
Four dMRI factors, thickness, & myelin for (A) von Economo structural types, B Mesulam’s hierarchies & C Yeo fMRI networks. Polar cortex had high kurtosis (F1). Granular cortex had higher F1 but lower anisotropy (F4) than agranular cortex. Paralimbic cortex had high complex diffusivity (F3) & F4. There was more F1, but less isotropic diffusivity (F2), F3 & F4 from heteromodal to idiotypic regions. Sensory & dorsal attention networks diverged from the four association networks for F2, F3 & F4.
