For a study published yesterday in The Journal of Neuroscience, researchers asked 20 participants to listen to a series of “persuasive messages.” While the test subjects listened, researchers used an fMRI to record the activity in various regions in their brains.

The subjects listened to messages covering a range of subjects, but the team, lead by Matthew Lieberman at UCLA, was really interested in a public service message about the importance of using sunscreen.
