The frontal lobes are important for cognitive control, yet their functional organization remains controversial. An influential class of theory proposes that the frontal lobes are organized along their rostrocaudal axis to support hierarchical cognitive control. Here, we take an updated look at the literature on hierarchical control, with particular focus on the functional organization of lateral frontal cortex. Our review of the evidence supports neither a unitary model of lateral frontal function nor a unidimensional abstraction gradient. Rather, separate frontal networks interact via local and global hierarchical structure to support diverse task demands.

额叶皮层和行为的等级控制

额叶对于认知控制很重要，但它们的功能组织仍然存在争议。一类有影响力的理论提出，额叶沿其尾尾轴组织以支持分层认知控制。在这里，我们更新了关于层次控制的文献，特别关注外侧额叶皮层的功能组织。我们对证据的审查既不支持侧额功能的单一模型，也不支持一维抽象梯度。相反，独立的正面网络通过局部和全局层次结构进行交互，以支持不同的任务需求。
