21. Cochlear implants convert speech and other sounds into electrical signals and transmit them to auditory nerve fibers. 22. The electrode wires then stimulate the auditory nerve , which carries signals to the brain for interpreting sound. 23. Another bit of evidence came from patients who had their auditory nerve removed because it was cancerous. 24. The orderly innervation by auditory nerve fibers gives the AVCN a tonotopic organization along the dorso-ventral axis. 25. These people have their auditory nerve severed, so the ear is no longer connected to the brain, 26. In contrast to hearing aids, which amplify sound, cochlear implants are designed to stimulate the auditory nerve . 27. The auditory nerve , also called the cochlear nerve, then transmits action potentials to the central auditory nervous system. 28. The axons of the auditory nerve originate from the hair cells of the cochlea in the inner ear. 29. These studies have measured the output of the auditory nerve ( AN ), with and without OCB stimulation. 30. They reflect neuronal activity in the auditory nerve , cochlear nucleus, superior olive, and inferior colliculus of the brainstem.
