Abstract
The most conspicuous aspect of the neural basis of language is the uneven involvement of the cerebral hemispheres. The familial distribution of variable degrees of left-hemispheric language lateralization was investigated. A significant familial aggregation of strong left-hemispheric language lateralization and a positive association of the degree of language lateralization between parents and their children were found. These data strongly suggest a genetic determination of the degree of language lateralization.
