Caffeine stirs memory: study
A jolt of caffeine can boost memory, according to a study published Sunday that provides a scientific motive for students slurping coffee, tea or energy drinks when cramming for exams. A team at Johns Hopkins University in Baltimore, Maryland, found that caffeine enhances certain memories for at least a day after they were formed. To strip out this confounding factor, a team led by Michael Yassa, an assistant professor of psychological and brain science, tried a different tack.
