I have a new paper that's just been published, titled "The functional overlap of executive control and language processing in bilinguals". We used conjunction analyses in fMRI to look at how the brain regions involved in linguistic executive control, non-linguistic executive control, and language processing might overlap differently in monolinguals and bilinguals. The main finding was that bilinguals showed overlap of these functions in the left inferior frontal gyrus, whereas monolinguals did not show any overlap. This suggests that bilingualism fundamentally alters the functional interdependence of language and executive control in the bilingual brain. I'm very proud of this study and think it's a fascinating finding!
