Selfish Teenager Brains?

"A new scientific study suggests that teenagers use a different part of their brains than adults to make decisions, resulting in a kind of selfishness. University College London neuroscientist Sarah-Jayne Blakemore asked people of various ages decision-making questions and questions about the well-being of others. In teenagers, the superior temporal sulcus lit up. In adults, the prefontal cortex was more active." /Boing Boing/
