fronto-parietal activation [90]. Also, the development of long-distance white matter connections has been shown to play an important role in the development of functional neural networks for executive control, both of which were associated with better performance [34]. There is thus evidence that protracted structural development is associated with more mature brain activation patterns, both of which appear to predict cognitive maturation. Future larger-scale multimodal and longitudinal neuroimaging studies will be necessary to further shed light on the association between structural and functional brain development, avoiding the confounds of cohort effects inherent to cross-sectional studies.
