Smarter People Have Bigger Brain Structures (Thanks to their Genes)

A large network of neuroscientists and doctors that compared over 30,000 brain images with people’s DNA says it’s found several genes that appear to influence the size of brain structures involved in intelligence and memory, as well as the volume of the brain itself. __
More on genes and brain size

Revolutionary advances in brain imaging and genomics are allowing neuroscientists to confirm what students of HBD have been saying all along: Genes influence both brain sizes and human intelligence.

In one of the largest research undertakings of its kind, a team of geneticists and neuroscientists has uncovered a number of genetic variations that influence the size of some key brain structures, including the hippocampus and the putamen. The result may advance understanding of such devastating neurodegenerative diseases as Alzheimer’s, Parkinson’s and Huntington’s.

Their findings, reported Wednesday in the journal…
