1. A method of stimulating neural tissue comprising: providing at least two electrodes suitable for contact with the neural tissue comprising neurons, each neuron within the neural tissue having a predetermined individual threshold of firing; and energizing each of selected two electrodes, selected from said at least two electrodes, at a level less than the predetermined individual threshold of firing of a neuron disposed directly adjacent either of the selected two electrodes, wherein the combined signal from said selected two electrodes is greater than the threshold of firing of a neuron between the selected two electrodes causing a percept different from a percept caused by a neuron disposed directly adjacent either of the two selected electrodes.
