Left-handed DNA found - and it changes brain structure
"For the first time in humans, we have been able to establish that these handedness-associated cytoskeletal differences are actually visible in the brain," Prof Douaud, who is herself left handed, said.
In the left-handed participants, the two halves of the brain - the left and right hemispheres - were better connected and more co-ordinated in regions involved in language.
The researchers speculate left-handed people may have better verbal skills, although they do not have the data from this study to prove it.
The study also showed slightly higher risks of schizophrenia, and slightly lower risks of Parkinson's disease, in left-handed people....
