Imaging time required to distinguish an individual's functional connectivity fingerprint from the population. A, Interindividual, intersession, and intrasession reproducibility shows only small differences and similar improvements with more imaging time used to construct measurements. B, Mean differences in correlations within the group and between the individual and the group with increased number of scans averaged. The black line shows α / sqrt(n) to project expected reproducibility if increasing numbers of group subjects are used. The individual and group values diverge with increased imaging time. C, Number of individual pairs of regions of interest, which are significantly different between the individual and the group over 95% of n resting scan samples selected from the individual's results.
