Paul S. Larson MD
Associate Clinical Professor and Vice Chair of Neurological Surgery
Chief, Neurosurgery Service, Veterans Affairs Medical Center
Principal Investigator, Movement Disorders Research
Dr. Larson's clinical interests are in stereotactic and functional neurosurgery, particularly with regard to movement disorders and psychiatric disorders. He has been involved in the development and evolution of novel surgical methods for deep brain stimulator implantation, including frameless techniques and the use of high-field, real-time intraoperative magnetic resonance imaging (MRI). He has extensive surgical experience in the use of intraoperative MRI for a number of neurosurgical applications. During his residency, Dr. Larson was extensively involved in the development of the Norton Hospital intraoperative MRI program, and spent a year in the Speed School of Engineering's Computer Vision and Image Processing Lab studying the basic science of CT and MR image analysis and 3D modeling.
Dr. Larson's research interests include neurostimulation, gene therapy, and other neurorestorative therapies for a variety of neurological diseases, including movement disorders and psychiatric disorders. He is also involved in studies using high-field MR brain imaging for clinical and basic science research. His basic science interests include MR research and the development of new technologies to perform functional neurosurgery using real-time MR imaging.
