Scientists identify a crucial brain feature connecting genetics to intelligence

A new study published in the journal Cerebral Cortex provides evidence that differences in general intelligence may be partly explained by the density of neurites within certain brain connections, and that this brain structure is, in turn, influenced by a person’s genetic makeup. The researchers found that individuals with higher genetic scores for intelligence tended to have a higher density of neurites in specific white matter tracts, and that this structural feature mediated the relationship between genetic variation and cognitive ability. The research addresses a longstanding challenge in neuroscience: understanding how inherited genetic differences relate to brain structure and...
