在理解语言的神经基础方面取得进展的一个长期障碍是模型系统的开发，该系统保留了与语言相关的认知行为，但允许侵入性细胞神经科学方法。最近在鸣禽身上进行的实验表明，这一类群可能会发展成为一种强大的动物模型，特别是对于语法处理的组成部分。然而，当在细胞或网络层面实例化时，语言感知的神经科学会是什么样子仍然未知。在这里，我们将语言感知解构为支持语法处理所需的最小认知过程集。然后，我们回顾了我们对鸣禽这些必要认知过程的神经机制的理解现状。我们注意到当前知识缺乏的地方，并建议这些机制最终如何结合起来，以支持能够处理不同复杂性的语法结构的新兴机制。
One longstanding impediment to progress in understanding the neural basis of language is the development of model systems that retain language-relevant cognitive behaviors yet permit invasive cellular neuroscience methods. Recent experiments in songbirds suggest that this group may be developed into a powerful animal model, particularly for components of grammatical processing. It remains unknown, however, what a neuroscience of language perception may look like when instantiated at the cellular or network level. Here we deconstruct language perception into a minimal set of cognitive processes necessary to support grammatical processing. We then review the current state of our understanding about the neural mechanisms of these requisite cognitive processes in songbirds. We note where current knowledge is lacking, and suggest how these mechanisms may ultimately combine to support an emergent mechanism capable of processing grammatical structures of differing complexity.
