在这篇文章中，它将被认为是腹内侧前额叶皮层（vmPFC）的关键贡献之一，以目标为导向的行动选择在于检索的价值目标是假定的结果的决策过程中，并在建立一个相对的偏好排名这些目标，考虑到每个不同的目标在考虑在一个给定的决策方案的价值。这些目标值信号，然后建议被用作输入到由大脑区域介导的VMPFC以外的在线计算的动作值，如顶叶皮层，辅助运动皮层和背侧纹状体的部分。总的来说，这些领域可以被认为是一个多阶段决策过程的组成部分，在计算实现这些目标的不同行动方案的价值之前，必须首先表示和排列不同目标的价值。
In this article, it will be argued that one of the key contributions of the ventromedial prefrontal cortex (vmPFC) to goal-directed action selection lies both in retrieving the value of goals that are the putative outcomes of the decision process and in establishing a relative preference ranking for these goals by taking into account the value of each of the different goals under consideration in a given decision-making scenario. These goal-value signals are then suggested to be used as an input into the on-line computation of action values mediated by brain regions outside of the vmPFC, such as parts of the parietal cortex, supplementary motor cortex, and dorsal striatum. Collectively, these areas can be considered to be constituent elements of a multistage decision process whereby the values of different goals must first be represented and ranked before the value of different courses of action available for the pursuit of those goals can be computed.
