Aging Adult Brain Connectome (AABC) Release 2
AABC Release 2 includes cross-sectional (V1) and longitudinal (V2, V3, V4) 3T MR scans and non-imaging phenotypic data from 1396 typically aging adults (ages 36-90+) in the HCP-Aging (HCA) and Adult Aging Brain Connectome (AABC) projects. This includes data for 1396 V1, 915 V2, 471 V3, and 96 V4 sessions (total = 2878). 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) from 1390 participants in 2789 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 is available for 282 participants. Multi-modal Imaging Derived Phenotypes (IDPs) are available for participants with imaging data.
