POET 3.08 | Thinking clearly on the brain

What is "The Brain Health Initiative"? Why is it that so many aspects of brain function are so hard to understand? Why is cognitive dysfunction such a difficult topic to discuss? How far away are we from the days when we will have a biomarker that can help us in this area? Desiree Chappell presents, with her guests; Dr Lee A. Fleisher Professor and Chair of Anesthesiology and Critical Care, University of Pennsylvania and Miles Berger, Neuroanesthesiologist at Duke University Medical Center.
