四十多年来，青蛙的听觉一直是那些对听觉神经科学，神经行为学和听觉进化感兴趣的人的重要信息来源。青蛙听觉系统的个体特征可以在一个或多个其他脊椎动物类别中找到代表，但总的来说，青蛙内耳代表了声学信号处理中进化实验的聚宝盆。机械敏感毛细胞作为信号转导的焦点，在传入听神经的声信息编码中起着关键作用。在这篇综述中，我们提供了一个简短的描述，如何编码听觉信号的专门解剖和生理学的青蛙内耳和检查的作用，毛细胞生理学和它的影响编码的声音在青蛙的听觉神经。我们希望证明，青蛙的声音信号处理可以提供不仅在两栖动物，而且在爬行动物，鸟类和哺乳动物，包括人类的听觉进化和生物学的见解。
For more than four decades, hearing in frogs has been an important source of information for those interested in auditory neuroscience, neuroethology and the evolution of hearing. Individual features of the frog auditory system can be found represented in one or many of the other vertebrate classes, but collectively the frog inner ear represents a cornucopia of evolutionary experiments in acoustic signal processing. The mechano-sensitive hair cell, as the focal point of transduction, figures critically in the encoding of acoustic information in the afferent auditory nerve. In this review, we provide a short description of how auditory signals are encoded by the specialized anatomy and physiology of the frog inner ear and examine the role of hair cell physiology and its influence on the encoding of sound in the frog auditory nerve. We hope to demonstrate that acoustic signal processing in frogs may offer insights into the evolution and biology of hearing not only in amphibians but also in reptiles, birds and mammals, including man.
