[Intraoperative electrical cortical stimulation in cerebral lesions].
BACKGROUND
Intraoperative brain mapping is used during neurosurgery in functional cortex to facilitate the extent of cortical resection and to identify nonfunctional tissue to remove subcortical lesions.


OBJECTIVE
To describe the intraoperative brain mapping protocol that has been utilized in the Hospital Clínico San Carlos of Madrid, Spain. Detailed somatotopic motor, sensitive and language localization is possible using direct cortical electric stimulation in the awake patient.


CONCLUSIONS
Intraoperative brain mapping is a surgical adjunct used during lesionectomy in functional cortex. In addition to preserving functions, the other essential goal is to achieve a radical removal while attempting to minimize the associated morbidity.
