Gene for a thick cerebral cortex linked to high intelligence

A gene which may make people more intelligent has been discovered by scientists. Researchers have found that teenagers who had a highly functioning NPTN gene performed better in intelligence tests.

It is thought the NPTN gene indirectly affects how the brain cells communicate and may control the formation of the cerebral cortex, the outermost layer of the human brain, also known as ‘grey matter.’

Previously it has been shown that grey matter plays a key role in memory, attention, perceptual awareness, thought and language. Studies have also proved that the thickness of the cerebral cortex correlates with intellectual ability. However, until now no genes had been identified.
