A Study Using Brain Stimulation and Behavioral Therapy to Increase Extent of Resection in Low-Grade Gliomas

Following resection consistent with SoC, if there is evidence of residual tumor which cannot be resected due to invasion of hand-M1 but which is small enough to be covered by two four-electrode strips, these strips will be placed on the functional cortex of interest and secured to the dura. The location of the leads will be registered into the navigation software (either Medtronic Stealth or Brainlab). The dura will then be closed as watertight as possible, and the RNS System will be incorporated into the craniotomy on closure Prior to closure, four bone screws will be placed and registered to the intraoperative navigation system as internal fiducials to be retrieved for future procedures.
