HCP-Young Adult 2025
HCP-Young Adult 2025 includes updated processing on previously released 3T and 7T imaging data 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. HCP-YA includes high-resolution 3T MR scans from young healthy adult twins and non-twin siblings (ages 22-35) using four imaging modalities: structural images (T1w and T2w), resting state fMRI, task fMRI, and diffusion imaging. Processed data are available for 1071 subjects. We have removed processed data for subjects 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 data are available on all subjects. The Open Access Dataset includes imaging data and most behavioral data. To protect subject privacy, some of the data (e.g., exact age, which subjects are twins) are part of a Restricted Access dataset that requires an application.
