INDI or the International Neuroimaging Datasharing Initiative is dedicated to accelerating our understanding of the brain’s functional architecture through the implementation of open data-sharing and discovery-based science. Extending the original 1000 Functional Connectomes project, INDI houses 3000+ resting-state FMRI and anatomical datasets. To complement the imaging data INDI encourages contributors to share various phenotypic data, including behavioral questionnaires and cognitive test results as well as physical measures (height, weight) and even DNA samples. These data are aggregated from over 30 independent international...

The ADHD-200 Sample is a grassroots initiative, dedicated to accelerating the scientific community’s understanding of the neural basis of Attention Deficit Hyperactivity Disorder (ADHD) through the implementation of open data-sharing and discovery-based science. Towards this goal, the ADHD-200 consortium has publicly released 776 resting-state fMRI and anatomical datasets aggregated across 8 independent imaging sites, 491 of which were obtained from typically developing individuals and 285 in children and adolescents with ADHD (ages: 7-21 years old). Accompanying phenotypic information includes: diagnostic status, dimensional ADHD...
