A Better Brain Map on the Way Surgeons removing tissue that edges "eloquent" areas of the brain-those tied to the basic ability to communicate-are well aware of the risks. The prospect of stopping seizures while making a patient forever mute is the stuff of nightmares. So when cortical mapping (electrical cortical stimulation or ECS) came to Hopkins more than a decade ago, it mercifully revealed a patient's individual speech, motor and other danger zones before surgery. In place at a handful of medical centers worldwide, ECS has opened the door to previously "un-doable" brain surgery for tumors, vascular flaws or epilepsy.
