Closed-Loop Stimulation

Closed-loop stimulation is a form of neuromodulation that provides therapeutic stimulation only when necessary. While it has been explored for conditions such as Parkinson’s disease, the most developed application of this emerging technology is in the treatment of refractory epilepsy – when seizures cannot be adequately controlled by medication alone. Much like a pacemaker stops abnormal heart rhythms, a closed-loop device aims to halt epileptic seizures by delivering stimulation when it detects the beginnings of seizure activity. NeuroPace, Inc. (Mountain View, CA), has developed a programmable responsive neurostimulation (RNS) brain implant that received pre-market approval from the FDA in November 2013. (1)
