Comparison of the AP-ECAP and FM-ECAP thresholds under different FSANs. The AP-ECAP threshold was comparable to the FM-ECAP threshold under the “normal” FSAN, but both were significantly higher than the corresponding EABR threshold (a). The results under the “abnormal” FSAN were the same as those under the “normal” FSAN (b). AP-ECAP alternating polarity electrically evoked compound action potential, FM-ECAP forward-masking subtraction electrically evoked compound action potential, EABR electrically evoked auditory brainstem response, FSANs functional states of the auditory nerve, A: AP-ECAP, F: FM-ECAP, E: EABR, E1–E4: electrode 1–electrode 4, *p < 0.0001, Kruskal–Wallis by ranks version of one-way ANOVA, followed by Dunn’s method. The data are represented as the mean ± SEM
