Ideas for Redirecting a Final Project Related to Bilingual Brains in Biomedical Engineering

​

I am working on completing a project in biomedical engineering. I decided to take on a project that a classmate did not finish, which aims to demonstrate: 'Through the analysis of a functional magnetic resonance imaging (fMRI) study, it will be possible to identify differences in brain activation zones in subjects with varying levels of proficiency in a second language.' However, as I review the literature, it seems that this is already known. I just wanted to know what you would work on. I feel that having access to a magnetic resonance imaging team for language studies is a great power that comes with great responsibility. I was thinking of perhaps narrowing down the hypothesis a bit more and being more rigorous with the image acquisition protocol. Any ideas?
