Lateralization Of Cerebral Functions

Abstract

A review of the literature on the localization of chronic adult aphasia leads to the conclusion by the authors that cerebral dominance seems unique to the left hemisphere. Individuals commonly regarded as left-handed are more likely to be ambidextrous. The left hemisphere was involved in practically all subjects studied. Two exceptions appear: those brain-injured prior to the 2d year of life; and those few subjects who have endured total left hemispherectomy. Intellectual functions not involving language appear to be particularly impaired by right hemisphere lesion.
