不同背景噪音条件下听觉响应延时及精确性的变化

First spike latency and jitter of A1 neurons for tones in different background noises. A: The response scatter of the sample neuron to the target tone under different noise background. The black dot represents the first action potential. B: The FSL of the sample neuron increases with the enhancement of background noise. C: The jitter of FSL showed no significant change along with the elevation of background noise intensity. D: The FSL of 15 cases to target stimulation are prolonged with the increase of background noise (^*P=0.001, ^**P=0.002, ^***P < 0.001, vs 0 dB). E: The background noise intensity has no significant effects on the jitter of group (paired-sample t-test, P=0.58, P=0.86, P= 0.06, P=0.32, vs 0 dB).
