Developmental and age‐related changes do not necessarily mean that different genes determine individual differences at different ages. However, participants differ in the speed in which their functional brain activity matures, and this difference is heritable (Vandenbosch et al., 2019). It is also evident that developmental changes occur with variable rate across time and space (Niedermeyer, 1999b). For example, communication between brain areas changes such that qualitatively different patterns in the functional connectivity network appear, changing from a relatively random to a more ordered network structure (Boersma et al., 2011; Smit & Anokhin, 2016). During the same developmental period, the network topology changes in the minimum spanning tree parameters of graph diameter and maximum centrality (Tewarie et al., 2015).
