Stereotactic and functional neurosurgery at IU School of Medicine is particularly strong in the areas of epilepsy, movement disorders and radiosurgery. For epilepsy, faculty perform focal resections, stereotactic laser ablation, responsive neurostimulation, deep brain stimulation and vagal nerve stimulation. While surgeons in this specialty currently implant electrodes to localize epileptogenic foci using frame-based and frameless techniques, the department anticipates acquiring the technology to robotically implant electrodes to enhance diagnostic yield.
The stereotactic and functional specialists perform awake and asleep deep brain stimulation, with or without microelectrode recording, for Parkinson’s disease, essential tremor, dystonia and epilepsy. The department has a Gamma Knife Perfexion Unit for stereotactic radiosurgery. Faculty also collaborate with biomedical engineers at nearby Purdue University to study the use of cerebral excitatory/inhibitory ratios to predict the onset of seizures.
