Hearing function after noise exposure. ABR thresholds measured before and 2 weeks after exposure to (A,B) 80 dB SPL or (C,D) 115 dB SPL for 1 h in Vglut3fl/fl mice. B, D, Representative traces. Numbers above traces indicate ABR wave number. Data are mean ± SEM; n = 6 mice. E, Phalloidin staining of cochlea of Vglut3fl/fl mice 2 weeks after 115 dB SPL noise exposure. Scale bar, 10 µm. **p < 0.01. ***p < 0.001.
