Note: ICC values for older controls were computed with white matter, CSF and non-brain signals as the nuisance regressors and averaged across all units (voxels, ROI pairs and nodes), unless noted otherwise.

#

Seeded separately at posterior cingulate cortex (PCC), supplementary motor area (SMA), and the inferior parietal sulcus (IPS) and ICC averaged across significant voxels (positive and negative)

+

Modal ICCs of voxels in the identified components

a

Mutiple networks; White matter, CSF, global signals and movement parameters removed (Shehzad et al., 2009)

b

Whole brain network based on ROIs defined by automated anatomical labeling (AAL) altas. White matter, CSF signals and movement parameters removed (Schwarz and McGonigle, 2011)

c

Components associated with sensory, motor, higher order cognitive function and the default mode network (Zuo et al., 2010).

d

Whole brain network based on ROIs defined by AAL, Harvard-Oxford atlas and meta-analysis. Global signal and movement parameters removed (Wang et al, 2011). Indicate that values listed are means (except where specified)
