Electrocorticographic mapping of expressive language function without requiring the patient to speak: A report of three cases

Conclusions The results of this study provide encouraging preliminary evidence that it may be possible that a brief and practical protocol can identify expressive language areas without requiring the patient to speak. This protocol could provide the clinician with a map of expressive language cortex within a few minutes. This may be useful as an adjunct to ECS interrogation, or as an alternative to mapping using functional magnetic resonance imaging (fMRI). In conclusion, with further development and validation in more subjects, the approach presented here could help identifying expressive language areas in situations where patients cannot speak in response to task instructions.
