In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by the auditory nerve. Their research challenges the prevailing view of the last 60 years that age-related hearing loss is mainly driven by damage to the stria vascularis, the cellular “battery” that powers the hair cell’s mechanical-to-electrical signal conversion.Read more
Mass. Eye and Ear scientists report the identification of a new pathway linked to cell division in the ear. With this pathway, they were able to reprogram the inner ear’s cells to proliferate and regenerate hair cell-like cells in adult mouse models.
