Optimizing cochlear implant electrode selection

A method is described to allow for better selection of electrodes for neural stimulation, for example in a cochlear implant. A series of stimuli, at different stimulation levels, are provided at each electrode to be tested, and the neural response to each stimulus is measured, using an implanted ele...

Zusammenfassung:A method is described to allow for better selection of electrodes for neural stimulation, for example in a cochlear implant. A series of stimuli, at different stimulation levels, are provided at each electrode to be tested, and the neural response to each stimulus is measured, using an implanted electrode. A value is then calculated relating stimulus level to response, to allow the relative responsiveness of electrodes to be determined. This can then be used as the basis for a stimulation map used to select which electrodes are stimulated and at what level.
