当特定物种的声信号的幅度调制在传输通道中失真时，信号变得难以被接收器识别。容忍的听觉模式识别系统，在感知到正确的物种特异性信号后，暂时扩大了它们对信号的接受，这对动物适应环境的约束是有利的。使用一个很好的研究蟋蟀物种，蟋蟀bimaculatus，我们分析了在听觉转向响应“奇”啁啾的耐受性，模仿信号失真的传输通道，并控制“沉默”啁啾通过采用一个精细的规模开环轨迹球系统。奇怪的鸣叫本身并没有引起声定向反应。然而，当插入到一个有吸引力的正常啁啾的呼叫歌曲模式，女性的声音定位反应对这些模式显着大于模式与沉默啁啾。此外，女性积极转向奇数啁啾时，这些都是在一系列有吸引力的啁啾。我们的研究结果表明，蟋蟀采用宽容的模式识别系统，一旦激活，短暂地允许响应扭曲的声音模式，只要有足够的自然鸣叫。由于模式识别调节蟋蟀如何处理非吸引人的声音信号，这一发现也与解释两个选择行为实验有关。
When the amplitude modulation of species-specific acoustic signals is distorted in the transmission channel, signals become difficult to recognize by the receiver. Tolerant auditory pattern recognition systems, which after having perceived the correct species-specific signal transiently broaden their acceptance of signals, would be advantageous for animals as an adaptation to the constraints of the environment. Using a well-studied cricket species, Gryllus bimaculatus, we analysed tolerance in auditory steering responses to ‘Odd’ chirps, mimicking a signal distorted by the transmission channel, and control ‘Silent’ chirps by employing a fine-scale open-loop trackball system. Odd chirps on their own did not elicit a phonotactic response. However, when inserted into a calling song pattern with attractive Normal chirps, the females' phonotactic response toward these patterns was significantly larger than to patterns with Silent chirps. Moreover, females actively steered toward Odd chirps when these were presented within a sequence of attractive chirps. Our results suggest that crickets employ a tolerant pattern recognition system that, once activated, transiently allows responses to distorted sound patterns, as long as sufficient natural chirps are present. As pattern recognition modulates how crickets process non-attractive acoustic signals, the finding is also relevant for the interpretation of two-choice behavioural experiments.
