Bilingual lexicon

With the amount of bilinguals increasing worldwide, psycholinguists have begun to look at how the brain represents multiple languages. The mental lexicon is a focus of research on differences between monolingual and multilingual brains.

Research during past decades shows that bilingual brains have special neural connections, and whether they constitute a distinct bilingual brain structure is still being studied. The mode of basic lexical representations of bilingualism has also been debated.
