Neurocognitive and neurolinguistics theories make explicit statements relating specialized cognitive and linguistic processes to specific brain loci. These linking hypotheses are in need of neurobiological justification and explanation. Recent mathematical models of human language mechanisms constrained by fundamental neuroscience principles and established knowledge about comparative neuroanatomy offer explanations for where, when and how language is processed in the human brain. In these models, network structure and connectivity along with action- and perception-induced correlation of neuronal activity co-determine neurocognitive mechanisms. Language learning leads to the formation of action perception circuits (APCs) with specific distributions across cortical areas. Cognitive and linguistic processes such as speech production, comprehension, verbal working memory and prediction are modelled by activity dynamics in these APCs, and combinatorial and communicative-interactive knowledge is organized in the dynamics within, and connections between APCs. The network models and, in particular, the concept of distributionally-specific circuits, can account for some previously not well understood facts about the cortical ‘hubs’ for semantic processing and the motor system’s role in language understanding and speech sound recognition. A review of experimental data evaluates predictions of the APC model and alternative theories, also providing detailed discussion of some seemingly contradictory findings. Throughout, recent disputes about the role of mirror neurons and grounded cognition in language and communication are assessed critically.

神经动作感知电路在语言,概念和交流方面的重用

神经认知和神经语言学理论做出了明确的陈述,将专门的认知和语言过程与特定的大脑位点相关联。这些联系的假设需要神经生物学的论证和解释。人类的语言机制最近的数学模型由基本神经科学原理的限制和对比较神经解剖学的报价为说明建立知识何处,何时以及如何语言是在人脑中处理的。在这些模型中,网络结构和连接性以及神经元活动的动作和知觉诱导相关性共同决定了神经认知机制。语言学习导致在整个皮层区域具有特定分布的动作感知电路(APC)的形成。这些APC中的活动动态模拟了语音和理解,语言表达,口头工作记忆和预测等认知和语言过程,APC内的动态以及它们之间的联系组织了组合和交流互动知识。网络模型,尤其是配电专用电路的概念,可以解释一些以前尚不为人所知的关于皮质“轮毂”进行语义处理的事实,以及运动系统在语言理解和语音识别中的作用。对实验数据的回顾评估了APC模型和替代理论的预测,还提供了一些看似矛盾的发现的详细讨论。贯穿整个过程,对有关镜像神经元的作用以及语言和交流中扎根的认知的近期争议进行了严格的评估。
