最近，许多实验试图识别与选择选项的主观值（SV）相关的神经信号。理论上，SV评估是决策过程中的一个中间计算步骤，其中将方案置于一个共同的尺度上，以促进价值最大化的选择。在这里，我们提出了一个定量的，基于坐标的荟萃分析206发表的功能磁共振成像研究调查SV的神经相关性。我们的研究结果确定了两种一般模式的SV相关的大脑反应。在一组区域中，SV对BOLD的正面和负面影响在文献中均以高于机会的比率报告。表现出这种模式的区域包括前额叶皮层、背内侧前额叶皮层、背侧和后纹状体以及丘脑。积极和消极影响的混合可能反映了潜在的U形功能，指示与唤醒或突出相关的信号。在第二组区域，包括腹内侧前额叶皮层和前腹侧纹状体，积极的影响占主导地位。在后一个区域，无论是面对决定还是交付结果，以及金钱和主要奖励，都可以看到积极的影响。这些区域似乎构成了一个“估值系统”，承载着一个领域通用的SV信号，并可能有助于基于价值的决策。
Numerous experiments have recently sought to identify neural signals associated with the subjective value (SV) of choice alternatives. Theoretically, SV assessment is an intermediate computational step during decision making, in which alternatives are placed on a common scale to facilitate value-maximizing choice. Here we present a quantitative, coordinate-based meta-analysis of 206 published fMRI studies investigating neural correlates of SV. Our results identify two general patterns of SV-correlated brain responses. In one set of regions, both positive and negative effects of SV on BOLD are reported at above-chance rates across the literature. Areas exhibiting this pattern include anterior insula, dorsomedial prefrontal cortex, dorsal and posterior striatum, and thalamus. The mixture of positive and negative effects potentially reflects an underlying U-shaped function, indicative of signal related to arousal or salience. In a second set of areas, including ventromedial prefrontal cortex and anterior ventral striatum, positive effects predominate. Positive effects in the latter regions are seen both when a decision is confronted and when an outcome is delivered, as well as for both monetary and primary rewards. These regions appear to constitute a "valuation system," carrying a domain-general SV signal and potentially contributing to value-based decision making.
