Quantifying network importance of nodes in the social brain. Normalized nodal closeness centrality, betweenness centrality, vulnerability, and dynamic importance of each social brain region were calculated and summed across network densities ranging from 10% to 50% (avoiding possible biases introduced by arbitrary choice of a single network density). Results were normalized by the mean of 100 matched random networks. Plots show mean and standard deviation (error bars) across all subjects. Numeric labels on the right of each plot show the brain region's rank, for each graph-theoretic metric, based on group mean values. The solid vertical line and dashed vertical lines are the mean and standard deviation of each metric across all social brain regions.
