Abstract:
The organization of language in the brains of multilinguals remains controversial. We investigated language representations in a highly proficient bilingual patient using a novel neuroimaging technique, intraoperative optical imaging of intrinsic signals (iOIS). Our results indicate cortical areas activated by both English and Spanish (superior temporal sulcus, superior and middle temporal gyri, and parts of supramarginal gyrus). In addition, language-specific areas were identified in the supramarginal (Spanish) and precentral gyrus (English). These results suggest that cortical language representations in bilinguals may consist of both overlapping and distinct components regardless of age of acquisition or proficiency of second language. Furthermore, this study demonstrates the utility of iOIS in detecting topographical segregation of cognitively distinct cortices.
