Figure 2.
C57 mice demonstrate normal hearing thresholds at a young age and develop age-related hearing loss beginning around 3 to 4 months of age. Panel A shows a basal turn of the spiral ganglion at 40x magnification of a young, 11 week-old, C57 with normal hearing. Panel B shows a basal turn of the spiral ganglion at 40x magnification of an old C57 between 8–12 months of age with age-related hearing loss.
