Note: Listed are the correlations from each seed set that are reliable (i.e., multiscan ICC > 0.5 for seed Sets A–B and multiscan ICC > 0.60 for Seed set C) and statistically significant (i.e., those correlations significant at the group level for each of the three scans). A higher ICC threshold of 0.60 was applied for seed Set C, due to the large number of correlations with ICC exceeding 0.5. For each brain region, the multiscan ICC and group-averaged correlation for each scan is given.
