Loss of OHCs and presynaptic ribbons after cisplatin 4 × 2 treatment. a–c Quantification of IHCs (a), OHCs (b), and presynaptic ribbons between IHCs and SGNs (c) was performed at 10 kHz, 20 kHz, and 40 kHz. Two-way ANOVA showed that OHCs’ IHC presynaptic ribbons were significantly lower at 40 kHz in the cisplatin group (n = 4) than in the saline group (n = 4). **p < 0.01 and ***p < 0.001. Data shown are the means ± 1 SEM
