A project that maps dopamine circuits in the prefrontal cortex through optogenetic manipulation was given top honors in this year’s annual Addiction Science Awards at the 2012 Intel International Science and Engineering Fair (ISEF) — the world’s largest science competition for high school students. The awards were presented by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and Friends of NIDA, a coalition that supports NIDA’s mission. The Intel ISEF Addiction Science Awards were presented at a ceremony Thursday night at the David L. Lawrence Convention Center in Pittsburgh.
