The first “boolean vision” device was released as an implant into the part of the brain that interprets vision signals that come from the retina. Connecting this implant with auxiliary image systems and databases provides for enhanced vision where supplemental data and images can be added to the information coming from the retina. A cortical implant is a chip or cable that is implanted into the visual cortex, the specific portion of the brain found at the back of the head that interprets visual information. This device transmits to the cortex the visual images received from a multitude of sources. The goal of this device is similar to a retinal prosthetic, but adds image data to the retina and optic nerve.
