Abstract: A prosthesis and specifically an aural prosthesis which includes an implantable component which is in connection with means which can selectively stimulate neural endings the component being arranged to receive a signal from an extension component which converts a parameter into a transmittable form and which includes a transmitter, the signal from the transmitter received by the implanted component which resolves the signal into groups of two components which can selectively stimulate the neural endings, the stimulation to each ending being independent to stimulation of each other neural ending in both intensity and phase.
