Understanding General Anesthesia\n

Principal Investigator Emery Brown


General anesthesia is a neurophysiological state in which a patient is rendered unconscious, insensitive to pain, amnestic, and immobile, while being maintained physiologically stable. General anesthesia has been administered in the U.S. for more than 160 years and currently, more than 100,000 people receive anesthesia daily in this country for surgery alone. Still, the mechanism by which an anesthetic drug induces general anesthesia remains a medical mystery. My laboratory is using a systems neuroscience approach to study how the state of general anesthesia is induced and maintained. To do so, we are using fMRI, EEG, neurophysiological recordings, microdialysis methods and mathematical modeling in interdisciplinary collaborations with investigators in BCS, the MIT/Harvard Division of Health Science and Technology, Massachusetts General Hospital and Boston University. The long-term goal of this research is to establish a neurophysiological definition of anesthesia, safer, site-specific anesthetic drugs and to develop better neurophysiologically-based methods for measuring depth of anesthesia.

Dr. Brown served on the National Institutes of Health (NIH) BRAIN Initiative Working Group, and is currently a member of the NIH Council of Councils, the National Science Foundation Mathematics and Physical Sciences Advisory Committee, the Board of Directors of the Burroughs-Wellcome Fund, the Board of Trustees of the International Anesthesia Research Society and the Scientific Advisory Committee of CURE Epilepsy. Dr. Brown is the recipient of an NIH Director’s Pioneer Award, an NIH Director’s Transformative Research Award and the 2011 Jerome Sacks Award for Outstanding Cross Disciplinary Research from the National Institute of Statistical Science. He is a Fellow of the American Institute for Medical and Biological Engineering, the American Statistical Association, the American Association for the Advancement of Science, the IEEE and the American Academy of Arts Sciences.
