Nora Volkow, MD
Addiction: Conflict Between Brain Circuits
Director of the National Institute on Drug Abuse, Bethesda, Maryland
2 Riverside Circle, Roanoke, VA 24016
Please note that the time for this event has changed to 11 a.m.
A shuttle will depart from Burruss Hall in Blacksburg at 10:00 a.m. and return at 12:15 p.m.
Research has taught us that disruptions in the fine balance that normally exists between brain circuits modulating reward, motivation, memory, and cognitive control underlie the behavioral manifestations of addiction. Dr. Volkow will highlight what we have learned about the modifications in circuitry that occur and how knowledge of these changes is leading to the design of new and improved pharmaceutical, behavioral, and combined treatments for drug addiction.
About the Speaker:
Nora Volkow, MD, directs the National Institute on Drug Abuse, which supports most of the world’s research on the health aspects of drug abuse and addiction. Dr. Volkow's work has been instrumental in demonstrating that drug addiction is a disease of the human brain. As a research psychiatrist and scientist, she pioneered the use of brain imaging to investigate the toxic effects of drugs and their addictive properties. Her studies have documented changes in the dopamine system that affect the actions of frontal brain regions involved in motivation, drive, and pleasure and the decline of brain dopamine function with age. She has also made important contributions to the neurobiology of obesity, attention deficit hyperactivity disorder, and the behavioral changes that occur with aging.
