Fig. 4. Noise-induced inner ear damage of larvae. A) Saccules of 5 dpf larvae. Four groups of tg(Brn3C-gfp) larvae were exposed to 3 different frequencies of noise (200 Hz, 1 kHz, and white noise, 140 dB) for 6 h. B) Number of hair cells in the saccule of each noise-exposed larva. The saccule was divided into 2 regions (anterior: small circular structure positioned at the rostral region; posterior: large circular structure positioned at the caudal region). There were no significant differences between the different frequency-exposed groups in both regions. Scale bar: 20 μm. R: rostral. D: dorsal. n = 40. |
