Sex equality in intrahemispheric language organization.
Sex differences in inter- and intrahemispheric cerebral organization, found in previous studies, have been used to explain sex differences in cognitive abilities. This study highlights data to contradict such widely held beliefs. Intrahemispheric language organization was examined by determining the location of lesions causing aphasia by computed tomography. No sex differences in the incidence of anterior, posterior, or central lesions was found. The distribution of left-hemisphere lesions in stroke patients, with or without aphasia, was also equal among the sexes. This study does not support the postulated gender difference in intrahemispheric cerebral organization.
