The language areas have been classically viewed as a posterior, perceptual Wernicke's region connected with an anterior, motor Broca's area via a tract of long fibers denominated the arcuate fasciculus. Recent connectional studies in the monkey indicate that there may be few direct connections between the regions strictly corresponding to Broca's or Wernicke's areas, and that inferior parietal areas may serve as a link between them. The proposed connectional pattern of the language regions fits the network of parietotemporal-prefrontal connections that participate in working memory, a type of memory used in immediate cognitive processing. Supporting this concept, brain activation studies in the human during linguistic working memory tasks have determined a close relation between the supramarginal gyrus (parietal area 40) and Broca's area. We suggest that language processing is closely related to working memory networks, and that the language regions in fact originated in evolution from a working memory network for linguistic utterances.
传统上，语言区域被视为一个位于后部的、负责感知的韦尼克区，它通过一束名为弓状束的长纤维与前部的、负责运动的布洛卡区相连。最近对猴子的连接研究表明，严格对应于布洛卡区或韦尼克区的区域之间可能几乎没有直接连接，而下顶叶区域可能充当它们之间的联系。所提出的语言区域连接模式与参与工作记忆（一种用于即时认知处理的记忆类型）的颞顶叶 - 前额叶连接网络相契合。支持这一概念的是，在人类进行语言工作记忆任务期间的大脑激活研究已经确定了缘上回（顶叶40区）和布洛卡区之间的密切关系。我们认为语言处理与工作记忆网络密切相关，并且语言区域实际上在进化过程中起源于用于语言表达的工作记忆网络。
