许多证据表明，外侧前额叶皮层（LPFC）参与了行为的执行控制。在早期的研究中，这一区域的神经元活动被认为在短时间内保留了即将到来的运动的信息，直到它们被执行。然而，后来的研究强调了它在行为规划的认知方面的作用，如行为意义，行为规则和行为目标。预期动作的结果（即目标对象状态的变化），而不是预期的运动，主要在规划期间的LPFC中表示。最近的研究表明，LPFC参与了概念过程中更抽象的方面，例如在行为规划阶段表示多个动作的类别。
Many lines of evidence implicate the lateral prefrontal cortex (LPFC) in the executive control of behavior. In early studies, neuronal activity in this area was thought to retain information about forthcoming movements for a short period until they were executed. However, later studies have stressed its role in the cognitive aspects of behavioral planning, such as behavioral significance, behavioral rules and behavioral goals. The consequence of the intended action (i.e. a change in the state of the target object), rather than the intended movement, is primarily represented in the LPFC during planning. Recent studies show that the LPFC is involved in more abstract aspects of conceptual processes, such as in representing categories of multiple actions at the stage of behavioral planning.
