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

Figure 2

Representative time-frequency tuning of IC neurons from exposed mice and their age-matched unexposed control measured immediately after (a, c) or at 12 weeks after cessation of noise exposure (b, d). Neurons (a) and (c) were from a region of IC tuned to 11 kHz; neurons (b) and (d) were from a region of IC tuned to 18 kHz. Dashed white lines show the frequency of 10 kHz.
