One exception to this rule, however, needs to be made: the “networks” (e.g., dorsal attention network, task control networks) referred to in the previous section were all initially defined by task-induced activations or deactivations in PET and fMRI studies. These groups of regions are not necessarily networks from the broader perspective, although in some cases they are explicitly treated as such (e.g., Dosenbach et al. 2007; Fair et al. 2008), making the “network” label correct in those situations. However, even when these groups of regions are not specifically treated as a network we will continue to use these labels, rather than creating unfamiliar labels, as they are widely accepted and recognized. To be clear, though, we believe the default mode “network” and task control “network” are subsets of potentially related regions within a much larger scale network of regions (Power et al. 2010b).
