The table describes one of the five motor resting-state networks detected at model order 40 and its subsequent (60–150) sub-networks. SAD significant connectivity differences (see Figure 3, second component from the left) are listed by: anatomical regions involved, number of voxels, and MNI coordinates (in mm) of maximum z-scores voxels, and center of mass.
