控制欲望的能力，无论是对食物，性还是毒品，使人们能够成功地在社会中发挥作用。然而，在诱人的情况下，强烈的冲动往往导致自我控制失败。尽管已经确定了许多自我控制失败的诱因，但问题仍然是为什么有些人比其他人更容易屈服于诱惑。在这里，我们结合了功能性神经成像和经验采样，以确定是否有大脑标记物可以预测人们在日常生活中是否会对他们的食物欲望采取行动。为此，我们研究了食物线索相关的活动在脑桥核（NAcc），以及活动与额下回（IFG）的反应抑制。NAcc活动与更大的可能性自我控制失败，而IFG活动支持成功抵抗诱惑。这些发现表明，在人们现实世界的诱惑体验中，欲望和自我控制的神经机制发挥着重要作用。
The ability to control desires, whether for food, sex, or drugs, enables people to successfully function within society. Yet, in tempting situations, strong impulses often result in self-control failure. Although many triggers of self-control failure have been identified, the question remains as to why some individuals are more likely to give in to temptation than others. Here, we combined functional neuroimaging and experience sampling to determine if there are brain markers that predict whether people act upon their food desires in daily life. To that end, we examined food cue-related activity in the nucleus accumbens (NAcc), as well as activity associated with response inhibition in the inferior frontal gyrus (IFG). NAcc activity was associated with greater likelihood of self-control failures, whereas IFG activity supported successful resistance to temptations. These findings demonstrate an important role for the neural mechanisms underlying desire and self-control in people’s real-world experiences of temptations.
