The results of the largest imaging study of the adolescent brain ever conducted, led by neuroimaging expert Robert Whelan and associate professor of psychiatry Hugh Garavan, are featured by The Wall Street Journal, CBS News, The Atlantic and the UK's Daily Mail on Sunday, among other major media outlets.
