Do we only use 10% of our brains? It's an appealing thought, according to an article in the September 2012 issue of Family Fun Magazine. It goes on to say that we all possess an enormous, secret store of unused brain power. But, according to Dr. Eric Chudler, a University of Washington neuroscientist and the founder of the website Neuroscience for Kids, there's no evidence to support the idea. "When you look at some one's brain, using a functional MRI or a PET scan, you don't see any part of it that's just sitting there doing nothing,: he says. Our minds do have plenty of untapped potential, though. "What's great about the brain is that it's so adaptable," says Chudler. "It's forming new connections whenever we learn skills."
