Question

Quizplus · Accepted Answer

Research has shown that children with higher intelligence have a thicker cortex in areas of the brain associated with intelligence, such as the prefrontal cortex. However, this increase in thickness occurs more slowly and over a longer period of time than in children with lower intelligence. Eventually, the cortex will become thinner as the brain optimizes for efficient processing.
