Comparison of the mean ABR thresholds of right ears from wild-type (euploid) mice and from Ts65Dn (Ts) mice, at ages ranging from 2 to 7 months. The results showed that the mean ABR thresholds to click stimuli and pure-tone stimulus (8 kHz, 16 kHz or 32 kHz) in the Ts65Dn mice (n = 53) were significantly higher than those of the wild-type control (n = 36). Error bars indicate standard deviation from the mean of each group. *P < 0.001.
