Aging Adult Brain Connectome (AABC) Release 1
AABC Release 1 includes cross-sectional (V1) and longitudinal (V2, V3) 3T MR scans and non-imaging data from 1248 healthy older adults (ages 36-90+) in the HCP-Aging (HCA) and Aging Adult Brain Connectome (AABC) projects. This includes data for 1248 V1, 762 V2, and 236 V3 in-person visits. It includes preprocessed and unprocessed imaging data for all included modalities (structural, high-res hippocampal T2 [unprocessed only], resting state fMRI, task fMRI, diffusion, and ASL) on 1248 participants in 2214 imaging visits. It includes non-imaging data collected over a broad range of domains at imaging visits and in remote follow up surveys (non-imaging events). 7 T Magnetic Resonance Spectroscopy (MRS) data are available for 138 participants. Multi-modal Imaging Derived Phenotypes (IDPs) are available for participants with imaging data.
