A computerized method of determining the focal point of electrical activity in the pallidum of parkinsonian patients was developed using on-line quantitative physiological data analysis. Thirty patients in a series of 70 were studied in depth. Neuron

A quantitative on-line analysis of electrical activity in the pallidum of Parkinsonian patients has been developed to determine the focal point of lesioning. A 3D volume image system has been developed to display basal ganglia anatomy and coregister

The first human stereotactic surgery based on intracerebral landmarks and Cartesian coordinates was performed in 1947. With this followed the publication of a number of stereotactic frames and atlases. The intercommissural line joining the anterior a

The rapid advances in the technology of, and accumulation of pertinent data in, electrophysiological testing has increased exponentially in the past decade. This is attributable to continued advances in computer technology, biomedical engineering, an

Current pharmacological therapy for Parkinson's disease loses its usefulness over time. Recently, pallidotomy, a surgical treatment for many of the symptoms of Parkinson's, has been re-investigated. This procedure requires localization of a small reg

Neural networks were trained using the ALOPEX technique to predict the outcome of pallidotomy, an operation performed to alleviate Parkinson's disease. Because of the limited number of operations performed, the training procedure relied heavily on si
