Study Overview
Mapping the human brain is one of the great scientific challenges of the 21st century.
The Human Connectome Project (HCP) has tackled key aspects of this challenge by charting the neural pathways that underlie brain function and behavior, including high-quality neuroimaging data in over 1100 healthy young adults.
Using greatly improved methods for data acquisition, analysis, and sharing, the HCP has provided the scientific community with data and discoveries that greatly enhance our understanding of human brain structure, function, and connectivity and their relationships to behavior.
The ‘HCP-style’ neuroimaging approach is being applied to a new generation of studies, including the Lifespan HCP and Connectomes Related to Human Disease projects.

Current Data Releases
HCP-Young Adult 2025 Released on 08/11/2025
Summary: HCP-Young Adult 2025 includes updated processing on previously released 3T and 7T imaging data (no new subjects) including spatial and temporal ICA and bias field correction on all fMRI data. We have repackaged the data to match packages released for the HCP Lifespan projects. Processed data are available for 1071 subjects. We have removed processed data for subjects from previous releases with processing errors and/or without a complete rfMRI run to enable MSMAll registration. Unprocessed data are available for all subjects with imaging data (1113 subjects). MEG data and 7T MR data are available for a subset of subjects (twin pairs). Phenotypic non-imaging data are available on all 1206 subjects.

1200 Subjects Data Release Released on 03/01/2017
Summary: The 1200 Subjects release (final release of new subjects) includes behavioral and 3T MR imaging data from1206 healthy young adult participants collected in 2012-2015. 3T structural scans are available for 1113 subjects. 46 subjects have 3T HCP protocol Retest data available. 184 subjects have multimodal 7T MR imaging data available. 3T and 7T Diffusion data for all subjects have been re-preprocessed with an updated diffusion pipeline that removes noise caused by subject movement. 3T diffusion bedpostX analysis datasets have been added.
