...Such a finding need not contradict the description of posterior members of the default mode system as cortical hubs (Buckner et al., 2009), but it may alter the understanding of what it means to be a hub....

...Standard approaches to forming whole-brain rs-fcMRI graphs often ignore this issue and define nodes as voxels (Buckner et al., 2009; Cole et al., 2010; Fransson et al., 2011; Tomasi and Volkow, 2011; van den Heuvel et al., 2008), large parcels from anatomically based brain atlases (Hartman et al....

...It should also be noted that several studies (Buckner et al., 2009; Cole et al., 2010) have implicated the default mode system as the seat of the most prominent ‘‘hubs’’ in rs-fcMRI brain graphs....

...Several previous analyses have demonstrated that connectivity among cortical regions is not random or proportionate across regions but rather exhibits “small world” properties, including hubs (Watts and Strogatz, 1998; Sporns et al., 2004; Achard et al., 2006; Bassett and Bullmore, 2006)....
