Neuroscientists who studied the brain scans of nearly 1,100 children and young adults across the U.S. from ages 3 to 20 found that the surface area of the cerebral cortex was linked to family income. They discovered that the brains of children in families that earned less than $25,000 a year had surface areas six per cent smaller than those whose families earned $150,000 or more. The poor children also scored lower on average on a battery of cognitive tests.
