成人大脑语言的功能神经解剖学将颞上回（STG）和额下皮层的语义和句法过程分开。目前尚不清楚发育中的大脑中是否存在类似的专门化。使用功能磁共振成像对 5 至 6 岁儿童和成人的句子处理的语义和句法方面进行了研究。尽管成人在 STG 和额叶盖中表现出功能特异性激活，但儿童在 STG 中这两个语言方面表现出很大的激活重叠。与成年人相比，他们参与了左右额下回的更多区域，这些区域众所周知支持资源需求过程。因此，语义和句法过程的语言网络尚未像成人大脑发育中那样专门化。
The functional neuroanatomy of language in the adult brain separates semantic and syntactic processes in the Superior temporal gyrus (STG) and in the inferior frontal cortex. It is unknown whether a similar specialization is present in the developing brain. Semantic and syntactic aspects of sentence processing were investigated in 5- to 6-year-old children and in adults using functional magnetic resonance imaging. Although adults demonstrated function-specific activations in the STG and the frontal operculum, children showed a large activation overlap for these two language aspects in the STG. Compared to adults, they engaged additional areas in the left and right inferior frontal gyrus, which are known to support resource demanding processes. Thus, the language networks for semantic and syntactic processes are not yet specialized similarly to adults in the developing brain.
