Familial aggregation of strong hemispheric language lateralization.
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.
