Complex systems analysis of anesthetic induction

and emergence

 

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

* Place : Physics 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.
