Fig. 3: Example correlation of Histology and MRI variables sampled in columnar parcels.
From: Diffusion MRI anisotropy in the cerebral cortex is determined by unmyelinated tissue features
a Comparison of dMRI fractional anisotropy to corresponding Nissl-HA and Myelin-HA from one parcel of corresponding tissue. b Comparison of magnetic transfer ratio (MTR) MRI contrast with myelin intensity in same parcel as a. In both a and b, the top row depicts nonlinearly co-registered histology parameter maps and MRI at 75 μm resolution. The red trapezoids indicate a columnar parcel example. The bottom row shows representative pixelwise scatter plots of the co-registered data within the sample parcel of cortex, and Pearson correlation (ρ) coefficients between histological variables and MRI variables.
