The paper describes the development of a harmonized multisite MRI protocol for pediatric brain imaging and validates its cross-site consistency.

This study examines how control energy in brain networks changes over time in older adults at risk for Alzheimer's disease, finding specific patterns linked to cognitive performance and biomarkers.

This study integrates multi-feature white matter connectivity into structure-function brain models, showing that myelin strongly predicts functional connectivity across brain regions and timescales.

This study shows how white matter myelin and tract caliber influence large-scale brain communication by shaping distinct functional connectivity patterns.

This study finds that coronary artery disease is associated with demyelination and increased iron deposition in white matter watershed regions, which correlate with cognitive decline.

The paper examines how cognitive states like resting and movie watching affect large-scale brain functional connectivity using fMRI data from the HCP and PNI datasets.

This study identifies white matter microstructural alterations in older adults with coronary artery disease using a multivariate approach and links them to cognitive performance.

The paper develops a computational framework to study superficial white matter organization using 3D histology and 7T MRI, finding high structural complexity in the first 2 mm below the cortical boundary and correlations with cortical geometry and connectivity.

This paper maps global cortical organization by integrating microstructural, connectivity, and functional data with cytoarchitectural maps, revealing a sensory-fugal gradient and functional diversity across brain areas.

The paper shares a multimodal 7T MRI dataset of ten healthy individuals, providing structural and functional brain data across multiple imaging modalities and parcellation scales.

The paper examines sex-specific and APOE4-related associations between cardiometabolic risk factors and white matter microstructure in individuals with a family history of Alzheimer's disease.

This paper introduces a novel method to map the aggregate g-ratio of white matter tracts using multi-modal MRI and compares it to conventional tractometry in healthy adults.

The paper describes a postmortem MRI protocol for the Douglas-Bell Canada Brain Bank to acquire high-resolution images while preserving tissue for histological analysis.

The paper characterizes weighted structural brain networks using white matter microstructural features to improve structure-function models.

Micapipe is an open pipeline for processing multimodal MRI data, generating structural and functional connectomes, geodesic distances, and microstructural profiles across multiple brain parcellations and surface spaces.

This study uses voxel-wise T2 relaxometry to analyze brain development in healthy infants and toddlers, providing maps of T2 evolution and comparing them to manual estimates.
