Ten ICNs from the analysis of the 29,671-subject BrainMap activation database (Right column of each pair: [37]) paired to 10 ICNs that were selected out of 20 components from the ICA analysis of the current rs-fMRI dataset (right column). The networks were paired using spatial cross-correlation with mean r = .46 (range = .25–.71); the weakest of these correlations thus has a significance of P = 10−5 (corrected). All ICA spatial maps were converted to Z statistic images via a normalized mixture–model fit, and then thresholded at Z = 3. The figure shows the 3 most informative orthogonal slices for each pair. ICNs are displayed in a gradient from red to yellow (3 < Z < 5), superimposed on the MNI152 standard space template image, in radiological convention (left = right). The r statistic is displayed at the top of each panel.
