ABR Peak 1 I/O function and suprathreshold amplitude and latency in the presence, absence, or repopulated macrophages at 16 and 22.6 kHz after exposure at 90 dB SPL noise level. A, ABR Peak 1 (P1) amplitude and (B) latency I/O function at 16 kHz at baseline (pre-NE), 1 d, and 15 DPNE. C, ABR Peak 1 amplitude and (D) latency I/O function at 22.6 kHz at baseline (pre-NE), 1 DPNE, and 30 DPNE. E, ABR Peak 1 amplitude and (F) latency at suprathreshold stimulus level at 16 kHz at baseline (pre-NE), 1 DPNE, and 30 DPNE. G, ABR Peak 1 amplitude and (H) latency at suprathreshold level at 22.6 kHz at baseline (pre-NE), 1 DPNE, and 15 DPNE. Values are mean (A–D), mean ± SD (E–H). Control chow (n = 6 cochleae), PLX6522 chow (n = 6 cochleae), and PLX5622 chow replaced with control chow (n = 5 cochleae). *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001; one-way ANOVA, Tukey's multiple comparisons test. ns, not significant.
