[Stereotactic target identification for neurosurgery of Parkinson disease]

The use of applied neurophysiological methods to improve the stereotactic localization of devices in the deep human brain is a high and systematic technology in Parkinson's neurosurgery today. The available standard equipment for clinical neurophysiology practice may constitute the basic set for high tech functional neurosurgery. Free run and event related multiunit recording, naturalistic and electrical evoked potentials, and deep brain microstimulation responses are the basic methodological set to neurophysiological target localization.

This article is concerned with the topic: set out a high technology using low cost equipment. So our 41 cases experienced in pallidal and thalamic nucleolisis and thalamus and subthalamus DBS results suggest that the proposed equipment and methods are the required to assure accuracy and safety for target location.
