Basilar membrane of the organ of Corti
The basilar membrane is the base structure of the organ of Corti. It is a flexible membrane that seperates the scala tympani from the scala media. It vibrates in responce to sound (the ripples in fluid of the scala vestibuli). The basilar membrane is wider at the apex than the base, and different areas of the membrane have stronger responces to different sound frequencies. The base is narrow and stiff, while the apex is wide and flexible.
- high frequencies have the largest effect at the base
- low frequencies have largest effect at the apex

Auditory nerve fibers in the organ of Corti
If the primary structure within the cochlea responsible for transducing mechanical sound vibrations into nerve impulses were to be completely non-functional, what would be the most direct and immediate consequence for an individual's auditory perception?
An individual is diagnosed with a form of hearing loss. Medical tests confirm that sound vibrations are correctly transmitted through the outer and middle ear structures. However, the inner ear fails to convert these mechanical vibrations into the electrical signals necessary for the brain to process sound. Based on this information, damage to which of the following structures is the most likely cause of this specific deficit?
