We have previously proposed that cortical auditory-vocal networks of the monkey brain can be partly homologized with language networks that participate in the phonological loop. In this paper, we suggest that other linguistic phenomena like semantic and syntactic processing also rely on the activation of transient memory networks, which can be compared to active memory networks in the primate. Consequently, short-term cortical memory ensembles that participate in language processing can be phylogenetically tracked to more simple networks present in the primate brain, which became increasingly complex in hominid evolution. This perspective is discussed in the context of two current interpretations of language origins, the "mirror-system hypothesis" and generativist grammar.
我们之前曾提出，猴脑的皮层听觉-发声网络可部分等同于参与语音回路的语言网络。在本文中，我们认为语义和句法处理等其他语言现象同样依赖于瞬态记忆网络的激活，而这些瞬态记忆网络可与灵长类动物的主动记忆网络相比较。因此，参与语言处理的短期皮层记忆集合在系统发育上可追溯到灵长类大脑中更简单的网络，这些网络在人类进化过程中变得越来越复杂。我们将在当前关于语言起源的两种解释，即“镜像系统假说”和生成语法的背景下讨论这一观点。
