Abstract
During deep brain stimulation, a neurosurgical procedure to relieve tremors, a thin electrode is inserted into deep brain regions to provide stimulation. Accurate electrode placement is crucial to provide tremor suppression without damaging adjacent optical and motor regions. A portable, real-time display fiber optic reflectance probe is used to obtain reflected signals from living, human brain tissues. The optical results are compared to pre-operative MRI scans to confirm anatomical structures and verify electrode placement. In addition to reflectance, tissue oxygen saturation may assist brain tissue identification.
