Callosal tracts and patterns of hemispheric dominance: A combined fMRI and DTI study

►Atypical hemispheric dominance for language is associated with high anisotropic diffusion in the corpus callosum. ►Typical cerebral asymmetry, such as left-cerebral dominance for language and right-cerebral dominance for spatial processing, is associated with reduced interhemispheric connectivity. ►Crowding of functions to the right hemisphere is associated with especially high anisotropic diffusion in the corpus callosum.
