Note: The total number of T1‐weighted MRI scans (N = 2,137) includes data from both individuals with stroke (n = 1,918, or 89.8% of the total dataset) and healthy individuals (n = 219, or 10.2% of the total dataset). A subset of the scans also includes repeated MRIs from the same individual (e.g., longitudinal data; n = 672 scans, or 31.4% of the total dataset).
