The Laboratory of Neural Prosthetics at Illinois Institute of Technology (IIT), Chicago, began growing a visual prosthetic the use of intracortical electrode arrays in 2009. While similar in principle to the Dobelle device, using intracortical electrodes allow for greatly elevated spatial resolution within the stimulation signals (greater electrodes according to unit area). In addition, a wireless telemetry machine is being developed to take away the want for transcranial wires. Arrays of activated iridium oxide movie (AIROF)-coated electrodes will be implanted in the visible cortex, located at the occipital lobe of the mind. External hardware will seize snap shots, manner them, and generate instructions that allows you to then be transmitted to implanted circuitry thru a telemetry hyperlink. The circuitry will decode the instructions and stimulate the electrodes, in turn stimulating the visual cortex. The organization is growing a wearable external photo capture and processing gadget to accompany the implanted circuitry. Studies on animals and psychophysical research on humans are being carried out to check the feasibility of a human volunteer implant.
Stephen Macknik and Susana Martinez-Conde at SUNY Downstate Medical Center are also growing an intracortical visible prosthetic, called OBServe. The planned system will use an LED array, a video digicam, optogenetics, adeno-associated virus transfection, and eye tracking. Components are currently being advanced and examined in animals.
