To explain investing decisions, financial theorists invoke two opposing metrics: expected reward and risk. Recent advances in the spatial and temporal resolution of brain imaging techniques enable investigators to visualize changes in neural activation before financial decisions. Research using these methods indicates that although the ventral striatum plays a role in representation of expected reward, the insula may play a more prominent role in the representation of expected risk. Accumulating evidence also suggests that antecedent neural activation in these regions can be used to predict upcoming financial decisions. These findings have implications for predicting choices and for building a physiologically constrained theory of decision-making.
为了解释投资决策，金融理论家援引了两个相互对立的指标：预期回报和风险。脑成像技术在空间和时间分辨率方面的最新进展使研究人员能够在做出金融决策之前可视化神经激活的变化。使用这些方法的研究表明，虽然腹侧纹状体在预期回报的表征中发挥作用，但脑岛在预期风险的表征中可能发挥更突出的作用。越来越多的证据还表明，这些区域先前的神经激活可用于预测即将到来的金融决策。这些发现对于预测选择以及构建一个受生理约束的决策理论具有重要意义。
