Comparison of the threshold gaps between the AP-ECAP and FM-ECAP as well as the corresponding slope gaps in the AGF under different FSANs. a The threshold gaps between the AP-ECAP and FM-ECAP were significantly smaller under the “normal” FSAN than under the “abnormal” FSAN. b AGF slope gaps of AP-ECAP and FM-ECAP under the “normal” FSAN were comparable to those under the “abnormal” FSAN. AP-ECAP: alternating polarity electrically evoked compound action potential, FM-ECAP: forward-masking subtraction electrically evoked compound action potential, AGF: amplitude growth function, FSANs: functional states of the auditory nerve, *p < 0.01, paired samples t test. The data are represented as the mean ± SEM
