This service covers testing an additional type of brain response during a scan that measures the brain's natural magnetic activity. A specialized machine detects tiny magnetic signals produced by brain cells as they respond to things like touch, sound, or light. Doctors use the results to map areas of brain function, often before surgery for epilepsy or a brain tumor.
