本文比较了理解前额叶皮层不同区域功能的三种不同框架——工作记忆、一般智力和监控系统方法。关于这些框架的第三个，讨论了三种不同的神经心理学证据。然后考虑了人类左右背外侧前额叶皮层的对比功能。左脑被认为参与对较低级别系统自上而下的战略调节，而右脑则被认为更关心检查正在进行的行为是否符合任务目标的控制。最后，评估了前前额叶皮层的功能；有人认为，它们与认知模式的变化有关，特别是当这涉及到实现先前设定的意图时。
Three different frameworks for understanding the functions of different regions of prefrontal cortex-working memory, general intelligence, the Supervisory System approach-are compared. Three different lines of neuropsychological evidence are discussed with respect to the third of these frameworks. The contrasting functions of the human left and right dorsolateral prefrontal cortex are then considered. The left is held to be involved in top-down strategic modulation of lower-level systems while the right is considered to be more concerned with the control of checking that on-going behaviour accords with task goals. Finally, the functions of anterior prefrontal cortex are assessed; it is argued that they are concerned with changes in cognitive mode, particularly when that involves the realization of previously set-up intentions.
