title: Probe-evoked potential findings following unilateral left-hemisphere lesions in children.
abstract: An evoked potentials procedure that has repeatedly provided evidence of predominant right-hemisphere engagement during language tasks in recovered adult aphasics was applied to the study of 14 children with early unilateral left-hemisphere lesions and in 14 matched normal subjects. In contrast with the adult patients, the children with left-hemisphere lesions displayed the normal pattern of predominant left-hemisphere engagement in visuospatial tasks. These data suggest that language restitution and development following early lesions involves intrahemispheric rather than interhemispheric functional reorganization.
