(A) For each subject, we computed the Pearson correlation R between the node driver and target centrality , (average energy to control other nodes from node i vs average energy to control node i from other nodes) and the in-strength and out-strength of effective connections, as well as the strength of functional connections . We show the distribution of |R| over subjects. (B) For each node, we computed the coefficient of variation (s.d./mean) over subjects of , , . We show the distribution of the coefficient of variation over nodes.
