复杂的经济决策——无论是为退休投资还是购买一些新的电子产品——往往涉及到我们的选择可能产生的后果的不确定性。解决这种不确定性的关键是战略元决策过程，它允许人们简化复杂的决策问题，根据各种情况评估结果，并灵活地将行为与环境的变化相匹配。近年来，大量研究表明背内侧前额叶皮层（dmPFC）参与行为的灵活控制。然而，几乎所有这些证据都来自于涉及执行功能或反应选择的范式，而不是复杂的决策制定。在这里，我们回顾证据表明，dmPFC有助于战略控制在复杂的决策。该区域包含一个功能性地形，使得后侧dmPFC支持响应相关控制，而前侧dmPFC支持策略控制。dmPFC前部的激活会改变决策问题的表现方式，进而影响大脑其他部位的计算过程。基于这些发现，我们论证了dmPFC对认知控制的广义贡献，以及其子区域根据任务需求和上下文的特定计算作用。我们还认为，这些战略考虑也可能对其他领域的决策至关重要，包括社会环境中的人际互动。
Complex economic decisions – whether investing money for retirement or purchasing some new electronic gadget – often involve uncertainty about the likely consequences of our choices. Critical for resolving that uncertainty are strategic meta-decision processes, which allow people to simplify complex decision problems, to evaluate outcomes against a variety of contexts, and to flexibly match behavior to changes in the environment. In recent years, substantial research implicates the dorsomedial prefrontal cortex (dmPFC) in the flexible control of behavior. However, nearly all such evidence comes from paradigms involving executive function or response selection, not complex decision making. Here, we review evidence that demonstrates that the dmPFC contributes to strategic control in complex decision making. This region contains a functional topography such that the posterior dmPFC supports response-related control while the anterior dmPFC supports strategic control. Activation in the anterior dmPFC signals changes in how a decision problem is represented, which in turn can shape computational processes elsewhere in the brain. Based on these findings, we argue both for generalized contributions of the dmPFC to cognitive control, and for specific computational roles for its subregions depending upon the task demands and context. We also contend that these strategic considerations are also likely to be critical for decision making in other domains, including interpersonal interactions in social settings.
