Methods for microelectrode-guided posteroventral pallidotomy.
Methods for localizing the posteroventral globus pallidus intermus are described. The authors' techniques include the use of microelectrodes to record single-unit activity and to microstimulate in human pallidum and its surrounding structures. This technique allows a precise determination of the locations of characteristic cell types in sequential trajectories through the external and internal ...
متن کاملStereotactic microelectrode-guided posteroventral pallidotomy and pallidal deep brain stimulation for Parkinson's disease.
Three patients underwent stereotactic posteroventral pallidotomy, and 1 patient underwent pallidal deep brain stimulation, for medically intractable symptoms of advanced Parkinson's disease, characterized by peak-dose levodopa dyskinesias, wearing-off fluctuations, tremor, rigidity and bradykinesia. Surgery was performed stereotactically under local anaesthesia, with eventual target coordinates...
متن کاملStereotactic radiofrequency pallidotomy with microelectrode mapping for treatment of Parkinson's disease.
1.0 CPT PROCEDURE CODE 61720 2.0 DESCRIPTION Pallidotomy is a neurosurgical procedure involving a surgical lesion of the globus pallidus, which lies in the basal ganglia portion of the brain, with the aim of controlling one or more of the major symptoms of parkinsonism, including tremor, rigidity, and hypokinesia, in those patients who have not responded adequately to medical treatment. 3.0 POL...
متن کاملTarget Prediction of Transcription Factors: Refinement of Structure-Based Method
Gene regulation in higher organisms is achieved by a complex system of transcription factors. Complete genome sequences of many organisms have opened up the possibility of systematic analysis of gene regulation at the genome level. Transcription factors usually bind to multiple target sequences and regulate multiple genes in a complex manner. Because there are a large number of transcription fa...
متن کاملA Multimodal, SU-8 - Platinum - Polyimide Microelectrode Array for Chronic In Vivo Neurophysiology
Utilization of polymers as insulator and bulk materials of microelectrode arrays (MEAs) makes the realization of flexible, biocompatible sensors possible, which are suitable for various neurophysiological experiments such as in vivo detection of local field potential changes on the surface of the neocortex or unit activities within the brain tissue. In this paper the microfabrication of a novel...
