Electrodes implanted in cochlear next to auditory nerve. Microphone (on belt) receives sound and transmits to electrodes. Electrodes directly stimulate the auditory nerve: who should get them. Destroy all residual hearing functions (wipe out deafness) Factors that can affect hearing: things that can"t control. The minor senses: smell, taste, and touch, are they really minor. Which sense would you least like to lose touch. Adequate stimulus is specific chemical compound: smell, taste. Respond only to specific shape of chemical compounds.
