MIT Technology Review kirjoittaa älykkyysosamäärän yhteydestä aivojen anatomisiin piirteisiin.
The brains of more intelligent children appear to develop in a characteristic way, growing quickly over an extended period between the ages of 5 and 12. These findings -- some of the most detailed research on brain development and IQ -- resulted from a 15-year study done by the National Institutes of Mental Health (NIMH.)

The study, which used magnetic resonance imaging (MRI) to gain a detailed picture of how the brains of children change over time, found that in kids who did better on standard IQ tests, the cortex grew thicker and faster and its growth peaked later than among their average peers.
