Maxima and locations of significant clusters within the default network and dorsal attention network. Clusterwise probabilities (CWP) are based on Monte Carlo correction for multiple comparisons within the default network and dorsal attention network ROIs. Local maxima (indented) are listed for clusters spanning both hemispheres.
