Figure 8. Permanent threshold shifts (PTS) of young (3-month-old) and middle-aged (7-month-old) SOD1 mice 14 days after chronic exposure in Exp. III. Thresholds were collapsed across frequency (3, 6 and 12 kHz) to illustrate differences among genotypes and age groups. Note trends for less PTS in Sod1 KO mice compared to Sod1 WT mice. Bars show SEM.Figure 8. Permanent threshold shifts (PTS) of young (3-month-old) and middle-aged (7-month-old) SOD1 mice 14 days after chronic exposure in Exp. III.
