  The relation between large-scale brain structure and function is an outstanding open problem inneuroscience. We approach this problem by studying the dynamical regime under which realisticspatiotemporal patterns of brain activity emerge from the empirically derived network of human brainneuroanatomical connections. The results show that critical dynamics unfolding on the structuralconnectivity of the human brain allow the recovery of many key experimental findings obtained fromfunctional magnetic resonance imaging, such as divergence of the correlation length, the anomalousscaling of correlation fluctuations, and the emergence of large-scale resting state networks.
