Abstract:The exploration of anesthesia and consciousness has always been an important subject in neuroscience, but the underlying neural mechanisms of consciousness are still unclear, which limits the development of anesthesia monitoring and consciousness evaluation systems. The neural correlates of consciousness (NCC) cannot be determined by a single brain region or mechanism, suggesting that consciousness may arise from complex interactions of brain functions on space and time scales. In order to characterize these interactions, network science has been introduced in exploring the mechanisms of consciousness. In this paper, the basic concepts and common indicators of brain network research are introduced, and the latest progress of brain network research in anesthesia is reviewed, so as to provide new ideas for the application of brain network indicators in clinical monitoring and provide directions for the exploration of NCC.
