许多种类蟋蟀的声音显示由脉冲串（啁啾）和间歇性停顿组成。在这里，我们调查的时间线索，女性的蟋蟀Teleogryllus狮子座用于检测脉冲和啁啾模式在两个不同的时间尺度。对于这两种模式，女性接受了广泛的组合，涵盖各自的脉冲和啁啾参数的歌曲的男性。在不同调制频率的连续脉冲序列的测试中，也确定了模式识别的传递函数。女性表现出两个范围的高反应分数，表明两个时间过滤器与抑制相互作用。对于脉冲模式的调制频率，偏好函数的峰值是相当尖锐的调谐，并在较低的脉冲率比男性产生的。这些结果表明，两个滤波器的组合输出并没有增加选择性，而是扩大了信号的可接受范围。
The acoustic display of many cricket species consists of trains of pulses (chirps) with intermittent pauses. Here, we investigated the temporal cues that females of the cricket Teleogryllus leo used to detect a pulse and a chirp pattern on two different time scales. For both patterns, females accepted a wide range of combinations that covered the respective pulse and chirp parameters in the songs of males. In tests with a continuous series of pulses at different modulation frequencies, the transfer function of pattern discrimination was also determined. Females exhibited two ranges of high response scores indicating two temporal filters with an inhibitory interaction. For the modulation frequency of the pulse pattern, the peak of the preference function was rather sharply tuned and at a lower pulse rate than produced by males. These results show that the combined output of both filters did not increase selectivity, but rather enlarged the accepted range of signals.
