UCLA team maps how genes affect brain structure, intelligence; dramatic images shed light on brain diseases, personality differences
...9,500 pairs of twins many of whom received brain scans
and cognitive tests. Their genetic similarity was confirmed by analyzing 78 different genetic markers. These individual pieces of DNA match exactly in identical twins, and half of them match in siblings. Recent research has shown that many cognitiv...
