Abstract

The main objective of brain surgery is complete tumor resection with maximal preservation of neurological function. Identification of eloquent areas before tumor excision is essential to surgical approach planning. Preoperatively, functional magnetic resonance imaging and diffusion tensor imaging can identify cortical and subcortical structures corresponding to motor and language areas. Direct intraoperative electrical, cortical and subcortical, stimulation is a reliable, accurate, and safe technique to map essential neurological networks during brain tumor surgery. Using this approach, targeted resection boundaries can be executed with greater precision, decreasing postoperative neurological deficits and hence improving patient quality of life.
