Tourette Deep Brain Stimulation (DBS) Target Detection & Suppression

Brief Summary

The investigators will implant and monitor 8 research subjects with a subcortical closed-loop system for detection and suppression of tics in subjects with medically refractory debilitating Tourette Syndrome. The project will use the FDA-approved "Medtronic Percept PC" device, which is an implantable neurostimulator capable of recording neural signals. The study will target the CM nucleus of the thalamus and the aGPi in each brain hemisphere from each subject and we will connect the two leads placed in each brain hemisphere to two Percept devices.
