Cortical Organization of Languages in Bilingual. Anouther area of bilingualism research that fraquently yields what appear to be contradictory findings is neurolinguistics. Neurolinguistic research with bilinguals usually focuses on hemispheric organization of the two languages and on location, size, and spread of activation associated with the two languages. The paradigms used include functional Magnetic Resonance Imaging (fMRI), Positron Emission Topography (PET) and ElectroEncephaloGrams (EEG), all of which rely on measuring cortical activity while brain resources are active.
