提出的想法是，布罗卡区（BA 44/45）和左腹侧前运动皮层（BA 6）以及额叶盖在语言处理过程中支持不同的功能。当需要根据顺序输入对层次结构进行内部重建时，BA 44/45 就会被越来越多地激活，而 BA 6 则参与局部结构依赖性的处理。这种功能分化是在表征 BA 6 的无颗粒结构和表征 BA 44/45 的颗粒异常皮质结构之间的神经细胞结构分化的背景下讨论的。这种区别在语言领域得到了例证，但也可能适用于非语言领域。
The idea is put forward that Broca's area (BA 44/45) and the left ventral premotor cortex (BA 6) together with the frontal operculum support different functions during language processing. While BA 44/45 is seen to be increasingly activated whenever the internal re-construction of a hierarchical structure from a sequential input is necessary, BA 6 is involved in the processing of local structural dependencies. This functional differentiation is discussed in the context of the neurocytoarchitectonical differentiation between agranular structure characterizing BA 6 and a dysgranular cortical structure characterizing BA 44/45. This differentiation is exemplified in the domain of language, but is possibly applicable to nonlanguage domains.
