Early biological concepts of language were predominantly corticocentric, but over the last decades biolinguistic research, equipped with new technical possibilities, has drastically changed this view. To date, connectionist models, conceiving linguistic skills as corticobasal network activities, dominate our understanding of the neural basis of language. However, beyond the notion of an involvement of the thalamus and, in most cases also, the basal ganglia (BG) in linguistic operations, specific functions of the respective depth structures mostly remain rather controversial. In this review, some of these issues shall be discussed, particularly the functional configuration of basal network components and the language specificity of subcortical supporting activity. Arguments will be provided for a primarily cortico-thalamic language network. In this view, the thalamus does not engage in proper linguistic operations, but rather acts as a central monitor for language-specific cortical activities, supported by the BG in both perceptual and productive language execution.
早期的语言生物学概念主要以皮质为中心，但在过去的几十年里，配备了新技术可能性的生物语言学研究，彻底改变了这种观点。迄今为止，连接主义模型将语言技能视为皮质基底网络活动，主导了我们对语言神经基础的理解。然而，除了丘脑的参与概念，在大多数情况下，基底神经节（BG）在语言操作中也有参与，各自深度结构的特定功能大多仍然存在相当大的争议。在这篇综述中，将讨论其中的一些问题，特别是基底网络成分的功能配置和皮质下支持活动的语言特异性。将提出一个主要的皮质-丘脑语言网络的论点。在这种观点中，丘脑本身并不参与适当的语言操作，而是作为语言特异性皮质活动的中央监测器，由 BG 在感知和生产语言执行中提供支持。
