For some adults, the use of a responsive neurostimulation (RNS) system implanted in the brain can help lessen or control seizures related to certain types of epilepsy. The device works similar to a pacemaker but is implanted in the brain and programmed to recognize a person’s seizure patterns to automatically respond. Researchers at Baylor College of Medicine found that the electrical stimulation improves verbal memory for those with RNS system when activated during certain memory tasks.
