Looking at teens' social networks may reveal how their brains work, says University of Pennsylvania neuroscience researchers. In a commentary on the Scientific American blog, Emily Falk, director of the Penn Communication Neuroscience Lab, and Michael Platt, director of the Wharton Neuroscience Initiative, note that by better understanding how teens make connections they can learn more about how to engage teens. For example, teens who are “information brokers,” having a knack for connecting people who wouldn’t otherwise know each other, come up with better solutions to problems, potentially because they are exposed to more diverse perspectives.
