ABR thresholds and suppression of wave I with contralateral noise in WT and KO mice. A, There were no significant differences in ABR thresholds for 15 kHz stimulus between WT and KO mice. B, Contralateral noise suppression of wave I was significantly larger for WT mice than for KO mice. C, There were no significant differences in the magnitude of contralateral suppression of wave I between the two groups of KO (altered and compensated behavior according to criterion 1). A–C, Mean ± SEM. D, Taking both genotypes together, there was a significant positive correlation between contralateral noise suppression of wave I and the number of correct responses during the period of C+T distractors (Spearman r₍₂₉₎ = 0.407, p = 0.029, linear regression equation: y = 56.347 + 5.4597x), however, no significant correlations were obtained analyzing each genotype alone. E, Analyzing all animals from both genotypes, a significant negative correlation between the magnitude of contralateral noise suppression of wave I and omitted trials was obtained (Spearman r₍₂₉₎= −0.556, p = 0.002, linear regression equation: y = 39.1554–7.1102x). However, no significant correlations were obtained analyzing each genotype alone. F, There were no significant correlations between accuracy in day 4 and contralateral noise suppression of wave I.
