Figure 11.

Example of a CN neuron. The format for all panels is the same as in Figures 3–5. (A) The BF was 23.4 kHz (indicated by the arrowhead) and the tested frequencies (f₁ = 23.4 kHz and f₂ = 25.9 kHz, white crosses) differ by 0.144 octaves. The PSTH of the accumulated response to all the frequencies (0.5 – 40 KHz) and intensities (0 – 80 dB SPL) presented (1 ms bins), as well as, the rate-level function at BF are shown in (B) and (C), respectively. The neuron exhibited a low CSI = 0.1 (Bootstrapping; p > 0.05) with a robust response across trials (D,E) and its frequency discriminability was not sensitive to the oddball condition (F,G). The AUC values in all conditions were slightly higher than 0.5 (Permutation test; ^*p < 0.05).
