Crossed aphasia elicited by direct cortical stimulation

摘要: I read with interest the article by Oishi et al.1 They report a patient right frontal tumor who was strongly handed (Edinburgh Handedness Inventory) but had aphasic seizures and dominant for speech on hemisphere Wada test. inserted subdural electrodes were able to show that during electrical stimulation of one electrode placed over inferior gyrus unable speak (count numbers, spontaneously, or name objects) totally intact auditory comprehension (he point at requested objects). concluded Broca area, in case crossed aphasia. Unfortunately, evidence presented authors is not sufficient conclude they localized language cortical stimulation. In high percentage cases, area immediately anterior primary motor (MI) face produces negative signs inability move tongue, eyes, other distal muscles extremities. Negative areas exist nondominant lobes.2,3 A effect tongue movements always associated comprehension. Therefore, cases where …
