* ABSTRACT

General anesthesia induces various states of consciousness under well controlled conditions. There is debate as to whether losing consciousness during general anesthesia is a continuous process or a binary process. In this talk, potential mechanisms for the loss of consciousness will be explained based on multivariate EEG analysis. Anesthetic-induced unconsciousness is associated with (1) reduced information integration capacity in the brain and (2) selective inhibition of the feedback information processing in the frontoparietal network. Finally, I will introduce another possible explanation based on graph theoretical analysis, which supports the idea that there is a distinct neurobiology for anesthetic induction and emergence.
