Does a conflict between inborn preferences and educational standards during childhood impact the structure of the adult brain? In a new study published in Journal of Neuroscience, Hartwig R. Siebner from the DRCMR , and co-workers demonstrated that left-handed people being forced to use their right hand acquire structural brain changes. The results are in accordance with a more general recent finding: The brain changes shape depending on its use.
