The MEG scanner works like a rapid-exposure camera, snapping a thousand pictures each second of electrical activity pulsing through the brain and across its surface. You can actually see a thought unfold in real time.

Advanced brain imaging techniques are turning up some cool observations:

Intelligence research is full of surprises. For example, the brains of smarter people, as measured by IQ, tend to be less active but more efficient, Haier says.
