In this lecture Dr. James McNames will present an overview of the activities of the Biomedical Signal Processing Laboratory at Portland State University. The focus will be on recent accomplishments in the processing of recordings acquired during stereotactic neurosurgery for the treatment of movement disorders at Oregon Health & Science University (OHSU). Parkinson's disease (PD) is the second most prevalent neurodegenerative disease, affecting over 500,000 people in U.S.A. and about 4-5% of people over the age of 85. Stereotactic neurosurgery is often used for patients whose condition has deteriorated and/or who are no longer responsive to drug therapy. One of the critical challenges to neurosurgeons who perform stereotactic neurosurgery in PD patients is locating the target structure within the brain. Once the target structure is located, the most common therapy is to install an implanted device similar to a pacemaker that continuously stimulates the target structure with voltage or current waveforms. Another critical challenge is determining how to optimize this stimulation waveform to maximize efficacy of the treatment, minimize power consumption, and minimize side effects. Some of our recent accomplishments in using signal processing techniques to help solve these problems will be discussed.
James McNames received a B.S. degree in electrical engineering from California Polytechnic State University, San Luis Obispo, CA, in 1992. He received both M.S. and Ph.D. degrees in electrical engineering from Stanford University, Stanford, CA, in 1995 and 1999, respectively. He has been with the Department of Electrical and Computer Engineering at Portland State University since 1999, where he is currently an associate professor. He has published over 90 peer-reviewed journal and conference papers. His primary research interest is statistical signal processing with applications to biomedical engineering and semiconductor manufacturing. Furthermore, he founded the Biomedical Signal Processing (BSP) Laboratory (bsp.pdx.edu) in fall 2000. The mission of the BSP Laboratory is to advance the art and science of extracting clinically significant information from physiologic signals. Members of the BSP Laboratory primarily focus on clinical projects in which the extracted information can help physicians or medical devices make better critical decisions and improve patient outcome.
