摘要 经济决策包含两个传统问题:跨期选择和风险决策。跨期选择分为冲动决策和自我控制,当冲动决策时,优先激活了与中脑多巴胺神经元相联系的旁边缘区域,包括伏隔核、眶额皮层中部和前额叶中部;自我控制即选择延迟决策时大脑双侧前额叶和后顶叶皮层神经活动增强。在风险和不确定性条件下,大脑皮层和杏仁核与风险决策联系密切。 Economic decision-making consists of two traditional problems: Intertemporal choices and Decision-making under risk and uncertainty. Intertemporal choice is divided into impulsivity and self-control. Paralimbic cortex, are preferentially activated by decisions involving impulsivity, including nucleus accumbens, orbitofrontal cortex in the central and middle prefrontal cortex; and regions of the lateral prefrontal cortex and posterior parietal cortex show enhanced changes in activity by self-controlled decisions. Cerebral cortex and amygdala are associated with the deciong-making under risk and uncertainty.
