Original abstract
Intraoperative analysis of the position of microelectrode in the globus pallidus only depends on experiences and subjective interpretation of microeletrode recording discharge of neurons during pallidotomy for Parkinson's disease. In this paper is reported a method for objective localization of microeletrode during neurosurgery. This method uses the factor of interspike interval based on microelectrode recordings. It is effective for identifying the change of the globus pallidal organism along the microelectrode pathway and the departure or deviation of the needle-pathway. The classification is consistent with the anatomic structures and the results of neurosurgery. This method can be used as a guide in pallidotomy. Globus pallidus.
