Neuroimaging: How do we peer deeply into the brain?
Marcus Raichle, M.D.
Marcus E. Raichle, M.D., is a Professor of Radiology, Neurology, Neurobiology and Biomedical Engineering at Washington University in St. Louis. He is also co-director of the Division of Radiological Sciences at Mallinckrodt Institute of Radiology. Dr. Raichle is known for his pioneering research in the development and use of an imaging technique called positron emission tomography (PET) to map specific brain areas used in emotion and in tasks such as seeing, hearing, reading and remembering. By using PET to monitor blood flow and metabolism in the human brain, Raichle and his collaborators have shown how the brain responds when a subject is asked to perform tasks as diverse as memorizing words or anticipating an unpleasant experience. In addition, they have mapped areas involved in attention, analyzed chemical receptors in the brain, investigated the physiology of major depression and anxiety and evaluated patients at risk for stroke.
Dr. Raichle received a bachelor’s and medical degrees from University of Washington in Seattle. His honors include election to the Institute of Medicine in 1991 and to the National Academy of Sciences in 1996. Most recently, he has received the Bristol-Myers Squibb Award for Distinguished Achievement in Neuroscience Research.
