Phosphoenix is developing a prosthesis to stimulate nerve cells in parts of the brain that are involved in visual perception. The prosthesis uses electrodes placed in the brain via a proprietary probe to artificially stimulate nerve cells. Stimulating one electrode produces the perception of a dot of light and stimulating multiple electrodes can generate recognizable patterns. In the final product, the patient will wear a pair of glasses with an incorporated camera, enabling them to see a simplified image of the outside world via the electrical stimulation of patterns in the brain.
