HCP Young Adult

Quick Reference: Open Access vs Restricted Data

Type: Software

For full details, see: HCP Data Release Documentation.

HCP Open Access data include brain imaging data (after defacing to remove identifying features) plus non-sensitive behavioral data. Investigators can view and use Open Access data by registering at db.humanconnectome.org and accepting the Open Access Data Use Terms, which includes an agreement to comply with institutional rules and regulations.
Open Access Data Use Terms

Access to data that could potentially be used to identify HCP participants is strictly controlled. Only investigators that are deemed to have a legitimate research interest in this data, and who agree to the Restricted Access Data Use Terms, will be granted access.
There are two tiers of restricted data, and therefore two tiers of restricted access.
  • Tier 1 Restricted Data refers to potentially identifying but non-sensitive information, such as Age (in years), Race/Ethnicity, and twin status.
  • Tier 1 Restricted Data Use Terms

  • Tier 2 Restricted Data refers to data that has a greater potential factor for allowing subjects to be identified, such as color vision and physiological data. Tier 2 also contains data that could be damaging to a subject if it became publicly known. This includes items such as drug/alcohol use and family psychological history.
