Vocal communication is a trait shared by most vertebrates. Non-mammalian model systems have provided exquisite examples of how motor and sensory systems, respectively, produce and encode the physical attributes of acoustic communication signals that play essential roles in mediating the dynamics of social behavior. These same models, mainly developed for a few species of fish, amphibians and birds, have proven to be equally important for demonstrating how steroids and other hormones shape the neural mechanisms of vocal communication. This review mainly considers recent studies in teleost fish demonstrating the role of steroids in the rapid modulation of the firing properties of a central pattern generator for vocalization. Thus, steroids, like other classes of neurochemicals, can play an instrumental role in reshaping the neurophysiological coding of motor patterning, in this case for social signaling behavior.
声音交流是大多数脊椎动物共有的特征。非哺乳动物模型系统提供了精妙的例子，展示了运动系统和感觉系统如何分别产生和编码声学交流信号的物理属性，这些属性在介导社会行为动态中起着至关重要的作用。这些主要为少数鱼类、两栖动物和鸟类开发的相同模型，已被证明在展示类固醇和其他激素如何塑造声音交流的神经机制方面同样重要。本综述主要考虑硬骨鱼的近期研究，这些研究证明了类固醇在快速调节发声中央模式发生器的放电特性中的作用。因此，类固醇与其他类神经化学物质一样，在重塑运动模式的神经生理编码方面可以发挥重要作用，在这种情况下是用于社会信号行为。
