thalamic nodes. The authors also measured the Euclidean distance between all pairs of ROIs, and noted that short-distance edges tended to be strong in children and weaken over development, whereas long-distance edges tended to be weak in children and strengthen over development, a trend that has been replicated in several studies, using both Euclidean and DTI-based distances (Fair et al., 2009; Kelly et al., 2009; Supekar et al., 2009).
