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

Figure 3

Averaged frequency tuning curves of IC neurons from exposed mice (filled circles) and their age-matched unexposed control (unfilled circles) measured immediately after (a) or at 12 weeks after cessation of noise exposure (b). Each frequency tuning was normalized on their maximum firing rates before averaging at different frequencies (1–32 kHz, 1 kHz increment). The standard deviation is shown by bars on and under each circle. Vertical dashed lines show the frequency of 10 kHz.
