Brain Tumor Mapping

Not all regions of the brain are alike. Some regions may be safely removed during tumor surgery, while other regions cannot. To remove brain tumors in close proximity or contained within functionally “eloquent” areas in a safe manner, functional neurosurgeons perform brain function mapping. This mapping may be performed before surgery with functional MRI to determine where language and key motor functions lie with respect to a tumor. During surgery, advanced electrophysiological techniques can be used to test the patient, who is sometimes awakened during surgery to test functions such as language that cannot be examined under anesthesia.
