Neurophysiological monitoring during astrocytoma surgery.
The technique of direct stimulation mapping of the cortex is used to identify regions of language representation in the dominant cerebral hemosphere and the Rolandic cortex in either hemisphere. The use of electrocorticography to remove epileptogenic zones in patients with difficult-to-control seizures is described. The article presents the authors' experience with brain mapping during glioma surgery to maximize the extent of tumor resection and minimize surgical morbidity.
