The HCP-D study aims to investigate how different parts of a child’s brain are connected and how these connections (the "connectome") change as the brain develops. Participants are children, adolescents, and young adults aged 5 to 21 years, recruited from four states in the United States of America (Washington, Minnesota, Massachusetts, and California) starting in 2017. A subset of participants (9-year-old females, 13-year-old females, 10-year-old males, and 14-year-old males) complete two additional follow-up assessments approximately 15 months apart. As of 2021, data has been collected from 652 participants, with the goal of recruiting over 1,300 participants.
