Definition: the fact that one hemisphere is dominant over the other and will thereby exercise greater influence over certain functions; the left cerebral hemisphere is usually dominant in the control of speech, language and analytic processing, and mathematics, whereas the right hemisphere (usually nondominant) processes spatial concepts and language as related to certain types of visual images; handedness (right-handed people have left cerebral dominance) is considered a general example of cerebral dominance.
