Example of a partially-adapting neuron in the IC. (A) FRA from a neuron with a BF of 29.9 kHz (arrowhead). The frequencies tested were f₁: 27.1 kHz and f₂: 30 kHz, at 70 dB SPL. (B–G) Same format as in Figure 3. This neuron displayed a significant level of SSA (CSI = 0.5, Bootstrapping; p < 0.05), responding to both tones across the 400 stimulus trials. Although, the neuron displayed significant discriminability in the equiprobable condition (S1, AUC = 0.57) (Permutation test; ^*p < 0.05), this was improved under the oddball sequences (S2, AUC = 0.61; S3, AUC = 0.76).
