The existence of a behavioral advantage of bilinguals over monolinguals during executive tasks is controversial. A new approach to this issue is to investigate the effect of bilingualism on neural control when performing these tasks as a window to understand when behavioral differences are produced. Here, we tested if early bilinguals use more language-related networks than monolinguals while performing a go/no-go task that includes infrequent no-go and go trials. The RTs and accuracy in both groups did not differ. An independent component analyses (ICA) revealed, however, that bilinguals used the left fronto-parietal network and the salience network more than monolinguals while processing go infrequent cues and no-go cues, respectively. It was noteworthy that the modulation of these networks had opposite correlates with performance in bilinguals and monolinguals, which suggests that between-group differences were more qualitative than quantitative. Our results suggest that bilinguals may differently develop the involvement of the executive control networks that comprise the left inferior frontal gyrus during cognitive control tasks than monolinguals [-]
