High spatial overlap but diverging age-related trajectories of cortical magnetic resonance imaging markers aiming to represent intracortical myelin and microstructure

Vertex-files for the paper "High spatial overlap but diverging age-related trajectories of cortical magnetic resonance imaging markers aiming to represent intracortical myelin and microstructure" published in Human Brain Mapping by Parent and colleagues (2023). https://doi.org/10.1002/hbm.26259

Anonymized vertex-wise files for each subject for the following cortical markers:

• Boundary Sharpness Coefficient (BSC)
• Grey-white Matter Contrast (GWC)
• Cortical thickness (CT)
• T1-weighted/T2-weighted (T1w/T2w) ratio sampled at 25% of CT in grey matter, 50% of CT in grey matter, and 25% of CT translated in the direction of superficial white matter (SWM)

Each vertex file is either surface-smoothed with a 5 mm full-width half-max (FWHM) heat kernel (supplementary analyses) or a 20 mm FWHM heat kernel (main analyses). Markers are further either in raw form or residualized for mean curvature at the vertex level.
