11. Acoustic over-exposure can also result in decreased myelination at specific points on the auditory nerve . 12. The electrode is wrapped around the insect's auditory nerve . 13. Removal of tumors often requires severing the auditory nerves . 14. While humans have 38 optic nerves for every auditory nerve , the sperm-whale ratio is one-to-one. 15. Cochlear implants transform sound into electrical impulses that stimulate the ends of the auditory nerves . 16. Removing the tumors often requires severing the auditory nerves . 17. These aid hearing by distributing sound as electrical signals to precise points on the auditory nerve . 18. Briefly, there are around 30, 000 auditory nerve fibres in each of the two auditory nerves. 19. In 1980, Don Johnson experimentally revealed phase-locking in the auditory nerve fibers of the adult cat. 20. Briefly, there are around 30, 000 auditory nerve fibres in each of the two auditory nerves .
