fMRI Research on the Bilingual Brain
In this article, I review the use of the functional magnetic resonance imaging (fMRI) technique to investigate the bilingual brain. Specifically, this review will discuss the types of research questions that can be (and have been) answered using this specific methodology, as well as questions this technique cannot answer. The review will then focus on providing a recent overview of fMRI studies of the bilingual mental lexicon, bilingual sentence processing, and the bilingual advantage in cognitive control. The pros and cons of this technique will be discussed in detail. This review will end with a discussion of the state of the art in the field of bilingual brain research and will provide avenues for future research directions to continue investigating the bilingual brain.
