The responsive neurostimulation system, or RNS, is surgically placed within the skull and positions small wires into the area of the brain where the seizures begin. Continuously monitoring brain activity, the device delivers a small burst of electrical stimulation that can stop seizures before they begin, and reduce seizures over time. (Courtesy of Neuropace)
