You knew caffeine made you more alert. But now scientists are saying it may actually improve your memory. Neurobiologist Michael Yassa, while working as an assistant professor of psychological and brain sciences at Johns Hopkins, found that caffeine has a positive effect on long-term memory in humans. Their research, published by the journal Nature Neuroscience, shows that caffeine enhances memories up to 24 hours after it is consumed.
The amount of caffeine required to enhance memory is the equivalent of about two cups of coffee.
Nathan Sterner sips some coffee and talks to Michael Yassa about his research.
