Abstract

A near-infrared fiber-optic reflectance probe that can be inserted into the brain during surgery to identify white and gray matter was developed. The probe was used along with a spectrometer to study the reflected signals from the brain during surgery. The probe is demonstrated to provide optical reflectance properties from structures deep within the brain. As it can be used to differentiate the boundary between gray and white matter, the probe can be used to guide pallidotomy surgery.
