hearing/vestibular/ear
• decreased number of BK channels
• mitochondria are concentrated in the center of the cytoplasm rather than along the plasma membrane, under the cuticular plate, and around the nucleus as in controls
• massive outer hair cell loss from the apical region at P40
• however, inner hair cells, spiral ganglion and stria vascularis appear similar to controls
• outer hair cell loss begins by P30 and continues with age with near absence by P80
• outer hair cell loss begins by P30 and continues with age with near absence by P80
• at P40, show low-frequency but not high-frequency hearing loss
