Noted: Neuroscientist Giulio Tononi, of the University of Wisconsin, agrees, but he cautions that their experiment only used one anesthetic and in one condition. ?To me, this [study] suggests a mechanism by which propofol can block inter-cortical communication.? In fact, rat studies using different anesthetics have also found slow oscillation, but found that some longer-range brain communication is still possible during unconsciousness, noted neuroscientist Nanyin Zhang, of the University of Massachusetts Medical School, who was not involved in the study.
