Highly replicable multisite patterns of adolescent white matter maturation

The paper presents a curated dataset of processed diffusion MRI data from the ABCD Study, showing that specific diffusion metrics are sensitive to adolescent white matter development and robust to image quality variation.

Development of the Left Arcuate Fasciculus is Linked to Learning Gains in Reading, but not Math

The study links longitudinal changes in the left arcuate fasciculus's white matter to reading development gains, but not math, using diffusion MRI and academic scores.

Educational Environment and White Matter Development in Early Adolescence

The paper examines how educational opportunity affects white matter development in adolescents, finding it correlates with accelerated development in academic-related tracts after controlling for socioeconomic factors.

White matter and literacy: a dynamic system in flux

The paper examines the relationship between white matter properties and reading skill development using longitudinal and cross-sectional data, finding that reading skill gains correspond to longitudinal white matter changes but not individual differences in white matter.

Development of the alpha rhythm is linked to visual white matter pathways and visual detection performance

This study links developmental changes in alpha rhythm to visual white matter maturation and visual detection performance using dMRI-EEG data.

An open, analysis-ready, and quality controlled resource for pediatric brain white-matter research

The paper curates and provides analysis-ready diffusion MRI data for pediatric brain white-matter research, including automated quality control using a trained neural network.

Evaluating the reliability of human brain white matter tractometry

This study evaluates the reliability of dMRI-based tractometry by assessing reproducibility, test-retest reliability, and robustness using software and datasets from the Human Connectome Project and clinical-grade measurements.
