Charting Cervical Spinal Cord Morphometry Across the Lifespan

The paper generates lifespan normative charts for cervical spinal cord morphometry using MRI data, revealing non-linear changes and sex differences across ages 0-100.

Genetic architecture of the limbic white matter microstructure in aging and Alzheimer's Disease.

This study identifies genetic loci and pathways associated with limbic white matter microstructure in aging and Alzheimer's Disease using multi-cohort diffusion MRI and bulk RNA-seq data.

Lifespan Trajectories of Asymmetry in White Matter Tracts

This study characterizes white matter asymmetry across the lifespan using a large dataset, revealing dynamic changes in asymmetry patterns with age.

White matter microstructure and macrostructure brain charts across the human lifespan

The paper develops normative reference charts for white matter microstructure and macrostructure across the lifespan using diffusion MRI data from 50 studies.

Analytic Bounds on GAMLSS Model Variability of Normative White Matter Brain Charts

The paper evaluates the variability of GAMLSS-based brain charts using analytic and empirical methods, finding low coefficient of variation across most white matter features.

MidRISH: Unbiased harmonization of rotationally invariant harmonics of the diffusion signal

MidRISH harmonizes diffusion imaging data by projecting sites to a mid-space, reducing reference bias compared to LinearRISH.

Learning site-invariant features of connectomes to harmonize complex network measures

The paper develops a variational autoencoder to harmonize multi-site diffusion MRI connectomes by isolating site-invariant features and preserving age-related modularity correlations.
