依靠声音交流来寻找配偶的动物，如蚱蜢，在识别自己物种特有的歌声模式方面非常准确。这就提出了一个问题，即它们是否也能解决一个更为复杂的任务，这个任务可能为配偶偏好和性选择提供基础：通过检测围绕共同物种特异性主题的微小变化来区分个体歌曲。使用尖峰列车的可辨别性，以量化的精度从模型蝗虫物种的听觉周边的神经反应，我们表明，信息足以区分歌曲是很容易在单细胞水平时，尖峰列车分析毫秒的时间尺度。
Animals that rely on acoustic communication to find mates, such as grasshoppers, are astonishingly accurate in recognizing song patterns that are specific to their own species,. This raises the question of whether they can also solve a far more complicated task that might provide a basis for mate preference and sexual selection: to distinguish individual songs by detecting slight variations around the common species-specific theme. Using spike-train discriminability to quantify the precision of neural responses from the auditory periphery of a model grasshopper species, we show that information sufficient to distinguish songs is readily available at the single-cell level when the spike trains are analyzed on a millisecond time scale.
