Epilepsy Electrodes (IMAGE) McGill University Caption Epilepsy patients with inserted electrodes often undergo cortical stimulation, a procedure that applies electrical current to the brain to map brain function but also to induce seizures for better understanding of the epileptic network. A new study finds that inducing seizures before surgery may be a convenient and cost-effective way to determine the brain region where seizures are coming from.
