Cochlear cells are specialized cells located in the cochlea, a spiral-shaped structure in the inner ear responsible for hearing. These cells play a crucial role in converting sound vibrations into electrical signals that the brain can interpret. There are two main types of cochlear cells: hair cells, which are sensory cells that detect sound, and supporting cells, which help maintain the structure and function of the cochlea. In humans, cochlear cells are essential for normal hearing. Damage to these cells can lead to hearing loss, as they do not regenerate naturally. Research is ongoing to explore potential treatments, including cochlear implants and regenerative therapies, to restore hearing function.
