Neuron activation induced by cochlear implants improved by new technology

Cochlear implants, electrical prosthetic devices that stimulate inner ear neurons of individuals who have lost their cochlear sensory cells, restore usable hearing to deaf patients. Cochlear implant electrodes are placed in the fluid-filled scala tympani of the cochlea, at a significant distance from the spiral ganglion and even from the spiral ganglion dendrites. Stimulation via a cochlear implant electrode pair is therefore likely to activate large numbers of neurons concurrently...
