Abstract
The effects of deep brain stimulation (DBS) have been studied primarily by cellular studies, which lack the ability to elucidate DBS-related responses on a whole-brain scale. 2-Deoxy-2-[F-18]fluoro-d-glucose positron emission tomography ([F-18]FDG-PET) reflects changes in neural activity throughout the entire brain volume. The aim of this study was to investigate the whole-brain effect of DBS on the glucose utilization in healthy rats. Seven rats were implanted with a DBS electrode in the right hippocampus and injected with [F-18]FDG to measure the glucose metabolism during DBS. Analysis reveals significant DBS-induced decreases in the glucose metabolism in the bilateral hippocampus and other limbic structures. This study demonstrates that DBS exhibits not only a local effect around the electrode tip but also in other limbic regions. [F-18]FDG-PET studies have the potential to provide better insight into the mechanism of action of DBS by simultaneously observing activity at multiple sites in the brain.
