Abstract
A method of stimulating neurons in a patient's cochlea. The method uses a plurality of cochlear electrodes, substantially arranged in a linear array within the cochlea and a relatively distant electrode. Charge is injected through a first one of the cochlear electrodes and an opposite charge is injected on either the relatively distant electrode; or a set of adjacent cochlear electrodes, being adjacent to the first one of the cochlear electrodes; or on a combination of the relatively distant electrode and the set of adjacent electrodes; and choosing the electrode or electrodes on which to inject charge in dependency on sound volume to be represented.
