The search for the anatomical basis of language has traditionally been a search for specializations. More recently such research has focused both on aspects of brain organization that are unique to humans and aspects shared with other primates. This work has mostly concentrated on the architecture of connections between brain areas. However, as specializations can take many guises, comparison of anatomical organization across species is often complicated. We demonstrate how viewing different types of specializations within a common framework allows one to better appreciate both shared and unique aspects of brain organization. We illustrate this point by discussing recent insights into the anatomy of the dorsal language pathway to the frontal cortex and areas for laryngeal control in the motor cortex.
传统上，对语言解剖学基础的探索一直是对特殊化的探索。最近，此类研究既聚焦于人类独有的大脑组织方面，也关注与其他灵长类动物共有的方面。这项工作主要集中在脑区之间连接的结构上。然而，由于特殊化可以有多种形式，跨物种解剖组织的比较往往很复杂。我们展示了如何在一个共同框架内看待不同类型的特殊化，从而使人们能够更好地理解大脑组织的共同和独特方面。我们通过讨论最近对通向额叶皮质的背侧语言通路和运动皮质中喉部控制区域的解剖学见解来说明这一点。
