This video adapted from NOVA scienceNOW explores new research concerning intelligence. Richard Haier and Rex Young are assessing intelligence by measuring brain structure instead of test performance. Using a new type of scanner that instantaneously detects brain activity, they are examining which parts of the brain are at work when we problem solve and how communication occurs across the network of gray and white matter. The scientists think that this kind of brain activity may not be the same for everyone and that such differences may be related to perceived levels of intelligence.
