An Age-Related Hearing Protection Locus on Chromosome 16 of BXD Strain Mice
(a) ABR thresholds of three age groups in parental D2 and B6 strains ( for each group). ABR thresholds of D2 and B6 mice were determined at three frequencies shown on the -axis. Error bars indicate the standard error of the mean (SEM). (b) Cross-sections (5 μm) through the modiolus of the cochleae from a D2 and a B6 mouse at the age of 6 weeks. Overall morphological characteristics of the basal turn () and degeneration of spiral ganglion cells and hair cells () were observed.
