A system and method for assessing causal signaling in the brain during states of consciousness are described. More specifically, a system and method for determining a directed functional connectivity in the brain wherein neurophysiologic correlates are analyzed with respect to feedback and/or feedforward activities to determine a directional feedback connectivity and/or a directional feedforward connectivity associated with a level of consciousness in the brain.
