However, an important lesson already apparent from these studies is that functional networks examined in isolation may appear quite different when examined within wider network contexts. We noted differential reports of functional connectivity within the DMN earlier in this review. Some studies, such as those of Fair et al. (Fair et al., 2008) or Kelly et al. (Kelly et al., 2009), suggested absent to minimal connectivity within the DMN in older children, whereas studies by Supekar et al. (Supekar et al., 2010) and Thomason et al. (Thomason et al., 2008) suggested substantial DMN connectivity at similar ages. In isolation, these differences appear quite striking. However, once the DMN is placed in a larger network with other cortical regions, it becomes clear that DMN regions are not isolated fragments of an immature adult functional system, nor are they unified in a cohesive DMN, but rather that DMN regions are actually integrated into a different network structure in children than adults (Fair et al., 2009). Communities in children are organized by anatomical proximity, suggesting that the various parts of the DMN should
