Why we should care about the dorso-medial prefrontal cortex in language production

Stephanie Ries

Associate Professor, San Diego State University

The dorso-medial prefrontal cortex (dmPFC), including the supplementary and pre-supplementary motor areas as well as the dorsal anterior cingulate cortex, has been a region of interest in studies of cognitive control and other areas of neuroscience for many years. Yet, traditional models of language production do not typically include this brain region, and its potential role in language and speech production has therefore only been more recently investigated. In this talk, I will review evidence from several research groups (including but not limited to my own) using fMRI, brain stimulation, and scalp and intracranial EEG in “monolinguals” and bilinguals with and without neurological damage that suggest that the dmPFC may play a bigger role than we previously had thought in language production. In particular, it seems likely involved in a response selection mechanism potentially taking place separately from lexical selection, in addition to speech monitoring. The implications of these findings for traditional cognitive models of language production will be discussed.
