Do We Really Only Use 10% of Our Brain?

With the new movie Lucy coming out and revolving around the idea that a woman who could use 100% of her brain would gain godlike powers, neurologist Krish Sathian of Emory University debunks the common myth that we only use 10% of our brains:

While the movie looks like a fun fantasy, it’s amazingly absurd to imagine that we would evolve all these extraordinarily useful powers without ever actually employing them (or that we would evolve them but then for no good reason stop using them). One would probably have to be a creationist to believe that such sophisticated powers, ones far beyond any human capacity, could be implanted in the brain despite never being employed. And then you’d have to think the God that created us with these unlocked powers was giving us this enormous set of potential and not giving us access to it. Which really wouldn’t be such a brilliant design, now would it?
