Long-Term Impairment of Sound Processing in the Auditory Midbrain by Daily Short-Term Exposure to Moderate Noise

Figure 4

Comparison of minimal threshold (a, b) and best stimulus level (c, d) of IC neurons from exposed mice (filled columns) and their age-matched unexposed control (unfilled columns) measured immediately after (a, c) or at 12 weeks after cessation of noise exposure (b, d). The averaged MT and BSL from exposed mice were normalized on that from unexposed control after averaging. Bars atop of column are the standard deviation. , , Student’s t-test.
