The goals of this project are to Modify microfabrication methods to produce 256 channel, implantable electrode arrays for the Lateral Geniculate Nucleus LGN Adapt visual neuroprosthesis RF coil and titanium package to fit in small hole in skull update external controller software Develop surgical insertion tool to deliver the electrodes to LGN In vitro bench testing of electrode arrays and insertion tools In vivo implantation and psychophysical testing in non-human primate animal model.The main accomplishments under this award were a the development of viable, microfabricated deep-brain stimulation electrodes and the means to deploy them using a unique, custom surgical insertion tool this assembly was the subject of a provisional patent application filed by sub-awardee Bionic Eye Technologies, Inc. and b the development of very low-stress Silicon Nitride material for the substrate on which the penetrating electrodes were micro-fabricated. This material was tested extensively in agarose gel models of brain tissue.
