Customizable Intraoperative Neural Stimulator and Recording System for Deep Brain Stimulation Research and Surgery.

TL;DRAbstract

Intraoperative targeting systems provide neurosurgeons with raw electrophysiological data through microelectrodes used for determining location in the brain. There are significant deficits to the available targeting systems, limiting the use in both clinical and research applications. The work presented in this dissertation is of the development and validation of an intraoperative neural stimulator and recording system for use in deep brain stimulation (DBS) surgeries. This intraoperative data acquisition system (IODA) was validated in three applications to ensure efficacy and improvements in research and clinical studies. The first application investigated was a clinical study illustrating the improvement IODA had on the targeting accuracy of DBS leads in the subthalamic nucleus (STN) over current targeting methods. It was demonstrated that the novel navigation algorithm developed for use with IODA targeted microelectrode probe locations significantly closer to final DBS lead position
