This theoretically means that the hemisphere contralateral to the dominant ...

The lateralization of brain function (or hemispheric dominance[1][2] / lateralization [3][4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum ...
