即使是一个晚上的完全睡眠剥夺(SD)也会对经济决策产生巨大影响。在这里,我们测试了一个新的假设,即SD通过改变估值过程来影响经济决策。利用功能性磁共振成像,我们确定了与金钱和社会奖励(有吸引力的女性面孔)的预期和体验相关的价值信号。然后,我们得出的决策值信号,预测每个参与者的意愿,以换取金钱的简短意见有吸引力的面孔在一个独立的市场任务。引人注目的是,SD改变了腹内侧前额叶皮层(VMPFC)的决策值信号,与经济偏好的相应变化成比例。这些偏好的变化是独立的SD的注意力和警惕性的影响。我们的研究结果提供了新的证据表明,VMPFC中的信号跟踪个人的当前状态,从而反映了不是静态的,而是构建的偏好。
Even a single night of total sleep deprivation (SD) can have dramatic effects on economic decision making. Here we tested the novel hypothesis that SD influences economic decisions by altering the valuation process. Using functional magnetic resonance imaging we identified value signals related to the anticipation and the experience of monetary and social rewards (attractive female faces). We then derived decision value signals that were predictive of each participant’s willingness to exchange money for brief views of attractive faces in an independent market task. Strikingly, SD altered decision value signals in ventromedial prefrontal cortex (VMPFC) in proportion to the corresponding change in economic preferences. These changes in preference were independent of the effects of SD on attention and vigilance. Our results provide novel evidence that signals in VMPFC track the current state of the individual, and thus reflect not static but constructed preferences.
