Age of language acquisition and cortical language organization in multilingual patients undergoing awake brain mapping

摘要

OBJECTIVE Most knowledge regarding the anatomical organization of multilingualism is based on aphasiology and. functional imaging studies. However, the results have still to be validated by the gold standard approach, namely electrical stimulation mapping (ESM) during awake neurosurgical procedures. In this ESM study the authors describe language representation in a highly specific group of 13 multilingual individuals, focusing on how age of acquisition may influence the cortical organization of language.
