Time evolution of spontaneous network
No single mode of brain connectivity is sufficient to fully explain how brain networks operate. It is sometimes proclaimed that the function of the brain will become apparent once we possess the brain's wiring diagram. Such views are overly simplistic, because the wiring alone does not account for the physiology of neural interactions, for the rich repertoire of spontaneous and task-dependent neural responses, or for their temporal patterning. At the same time, dynamic patterns of neural interactions cannot be fully interpreted unless structural connectivity is taken into account. Both structural and functional
networks (or their union in a suitable model of effective connectivity) are needed to fully explain the time evolution of spontaneous network activity or of neural responses to perturbation.
