Patent US 6,032,074

A method and system for enhancing the function of sensory cells. The method includes locating a sensory cell area associated with the sensory cell whose function is to be enhanced, and inputting a bias signal to the sensory cell area. The system includes a signal processor for producing a bias signal and an input device for inputting the bias signal to a sensory cell area associated with a sensory cell whose function is to be enhanced. Inputting the bias signal to a sensory cell area effectively lowers the threshold of sensory cells with which the sensory cell area is associated.
