In the eighteenth century, Benjamin Franklin, from his observations and experiments with electricity, appreciated that application of electrical stimulation to the brain could result in some type of visual sensation, and this formed part of a scientific address in 1751[55]. In 1953, Krieg outlined ˵two unexplored paths,″ the exploitation of which might result in aids for the blind – i.e., electrically induced stimuli applied to the skin (sensory prosthesis) or directly to the visual cortex (electroneuroprosthesis). He described the ways in which light signals from the environment might be transduced into electrical stimuli, which might be patterned in order to provide orientation of visual patterns.
