Within the inner ear there are thousands of tiny hair cells that detect sound waves and translate them into nerve signals that the brain interprets as sound. Damage to these hair cells is a leading cause of hearing loss for once these cells are damaged they cannot grow back. However, researchers have recently found a combination of drugs that increases the number of supporting cells in the ear and induces them to become hair cells. With more research these drugs could become a new way to treat hearing loss. To learn more, click here.
