 Language relies on two main neurocognitive components; a dedicated language network depending on perisylvian structures, and a domain-general control-executive and working memory system relying on prefrontal, particularly left cingulum and dorso-lateral prefrontal cortex DLPFC networks. The executive system is known to participate in language control in bilinguals, but also plays a role in many intra-languages processing, for mother language L1 and even more in second language production L2.
