Abstract: | We performed a selective Wada test on a bilingual patient. While a left middle cerebral artery (MCA) injection produced global aphasia for both (Spanish and English) languages, the patient could only speak Spanish (his mother tongue) 1 min after he started to speak English. No language disturbances were observed after a right MCA amytal injection. These findings suggest that all of a multilingual's languages are stored within the verbal-dominant perisylvian region, and while the second language may be organized within the central Sylvian core, the first language may be better represented in more distal perisylvian areas. |
