Fig. 2.
Mean VsEP thresholds for 19 inbred strains. Some strains were measured at two ormore ages. Age at testing is shown in parentheses. Normative ranges for young C57 mice (±2 standard deviations) are shown by horizontal dashed lines. Elevated thresholds for elderly C57BL/6J and LP/J mice suggest age-related functional changes. Several inbred strains have elevated VsEP thresholds. Many, but not all of these strains, also have hearing loss. Error bars reflect standard deviation.
