Figure 2

Genotype-dependent differences in the auditory brainstem response (ABR) amplitude-intensity profiles of PACAP-deficient (KO) and wild-type (WT) mice at 16.4, 32.8 and 65.6 kHz. (a) Asterisks indicate significant differences between KO and WT mice. Mean ± SEM; 2-way-ANOVA, Bonferroni post-hoc test. ****p < 0.0001, ***p < 0.001, **p < 0.01, *p < 0.05 vs. WT values at the corresponding stimulus frequency and intensity. (b) Example for absolute amplitude measurement at peak II. (c) Average traces (±SEM) at 32.8 kHz, 90 dB demonstrate the waveform differences between WT and KO mice. Two-headed arrows (↕) demonstrate the difference between peak I amplitude values (black: WT, red: KO).
