The evolution of language correlates with distinct changes in the primate brain. The present article compares language-related brain regions and their white matter connectivity in the developing and mature human brain with the respective structures in the nonhuman primate brain. We will see that the functional specificity of the posterior portion of Broca's area (Brodmann area [BA 44]) and its dorsal fiber connection to the temporal cortex, shown to support the processing of structural hierarchy in humans, makes a crucial neural difference between the species. This neural circuit may thus be fundamental for the human syntactic capacity as the core of language.
语言的进化与灵长类大脑的明显变化相关。本文将发育中和成熟的人类大脑中与语言相关的脑区及其白质连接与非人类灵长类大脑中的相应结构进行了比较。我们将看到，布洛卡区后部（布罗德曼区[BA 44]）的功能特异性及其与颞叶皮质的背侧纤维连接，已被证明支持人类对结构层次的处理，这使得人类与其他物种在神经方面存在关键差异。因此，这个神经回路可能是人类作为语言核心的句法能力的基础。
