토토 승무패/BK21 SEMINAR [6.16]

Complex systems analysis of anesthetic induction

and emergence

* Speaker: UnCheol Lee  (University of Michigan Medical School, Ann Arbor)

* Place : 야구 토토 Seminar Room (Science Bldg, 3-201)

* Date & Time : June  16 (Wed.)  10:30  ~  11:30 am

* 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.
