Abstract excerpt
In order to identify brain structural phenotypes that remain under significant genetic control in late adulthood, we examined the heritability of corpus callosum macrostructure (i.e. size) using MRI and microstructure (e.g. myelin) using diffusion tensor imaging in 15 monozygotic and 18 dizygotic twin pairs of elderly men. The relative proportion of genetic to environmental influences varied considerably by...
