ABR waveforms. Grand averages ± s.e.m. of ABR waveforms in response to 100 dB click stimuli presented at 20 Hz in 15 Otoferlin knockout animals (red) and 14 heterozygous littermates (black) used for pup vocalization studies. Roman numbers denote ABR wave peaks I-V according to Jewett in wild type animals, SP: putative summating potential component observed in knockout and control.
