Proposal of an optimized strategy for intraoperative testing of speech and language during awake mapping

In this paper, we review the literature about the definitions of errors observed by direct electrical stimulation during language testing. As a practical application, we propose an optimized strategy for differentiating accurately motor arrest, speech arrest, and anomia in the context of intraoperative mapping. Finally, we also discuss the anatomical correlates of the networks sustaining these different errors, both cortically and axonally.
