Growth Asymmetry Due to Lesions of the Postcentral Cerebral Cortex

It has long been obvious that decrease in growth of one half of the body, or of one member, may result from a lesion of the corresponding portion of the spinal cord at an early age or from a large birth injury of the opposite hemisphere of the brain. In the cases here described evidence will be presented to show that limitation of growth is produced by lesions of the cerebral cortex alone, but only if such lesions have a specific localization. Operative exposure of the brain of patients with focal epilepsy has given us opportunity to determine the exact location of cerebral scars and to identify the convolutions involved by means of electrical stimulation, with the use of local anesthesia. In the study of such patients certain cases came to our attention in which only the postcentral gyrus seemed to be involved in the lesion. Consequently, we have reviewed
