Figure 3: Tonotopic Maps Change with the Intensity.

(A) Tonotopic map at threshold intensity (upper) and at 30 dB above threshold (lower). The dotted circles indicate the low (blue) and high (red) frequency area, respectively. (B) The area ratio of the low frequencies (percentage of recording sites with a BF below 8 kHz in all the recorded sites) at threshold intensity and at 30 dB above threshold. **p = 0.0087, paired t-test, n = 16. (C) The area ratio of the high frequencies (percentage of recording sites with a BF above 32 kHz in all the recorded sites) at threshold intensity and at 30 dB above threshold. *p = 0.037, paired t-test, n = 16.
