Maps of essential nodes. Average map of influencers for the different centralities according to a betweenness centrality, b k-core centrality, c eigenvector centrality, and d closeness centrality. The maps are averaged over the six rats and the color bars are calculated according to the rank defined by Supplementary Note 4, Eq. (8). Yellow/white colors indicate the top influencers according to each centrality. According to these results, the centralities are then divided into e hub-centric centralities dominated by the hubs and identifying the hubs in the HC and f integrative centralities dominated by the weak nodes and identifying the low-degree nodes in the shell part of the NAc. The size bar in each panel corresponds to 0.5 mm
