Brain mapping during tumor surgery to protect important brain functions

This trial investigates using electrocorticography—a technique that records electrical signals directly from the brain surface during surgery—to identify and protect areas that control movement, sensation, and speech in patients having brain tumor surgery. The study compares this new mapping method with existing pre-surgery imaging and other intraoperative techniques to see if it helps doctors safely remove more tumor while preserving your function.

Brain tumors near critical areas make surgery risky—doctors must balance removing the cancer while avoiding damage to areas that control movement, feeling, and speech. This trial exists to test whether this new mapping method can help surgeons see these important areas more clearly and protect them better during surgery.
