Human Connectome Project (HCP) — Lifespan Studies
The Human Connectome Project (HCP) has expanded from its original young-adult study into a family of lifespan datasets spanning prenatal development through late adulthood. All datasets use HCP-style acquisition and processing principles to provide a coherent, cross-age resource for studying human brain connectivity across development, maturation, and aging.
This repository provides curated, tractography-ready derived diffusion MRI datasets (FIB, QSDR, GQI, SRC when permitted, QC tables).
Raw MRI data are not hosted here and must be obtained through ConnectomeDB, NDA, or dHCP under each dataset’s data-use agreement.
Overview
The HCP Lifespan initiative aims to:
- Map connectivity trajectories from the prenatal period through 100+ years
- Maintain HCP-level acquisition quality using age-appropriate MRI protocols
- Enable cross-sectional and longitudinal modeling of brain development
- Support genetics, behavior, multimodal imaging, and lifespan integration
- Provide harmonized derivatives to accelerate reproducible neuroscience
This repository distributes DSI Studio–ready diffusion derivatives to reduce preprocessing load and standardize tractography workflows.
