决定控制情绪反应是应对环境挑战的基本手段，但人们对预测这种决定结果的神经机制知之甚少。我们使用功能性磁共振成像来测试人类大脑在最初看到负面图像时的反应是否可以用来预测对这些图像的情感反应的决定。我们的研究结果表明：（1）在杏仁核和前额叶皮层中已知参与情绪认知控制的区域内表现出较高平均水平活动的个体中，调节的决定更频繁;（2）在与调节情绪相关的分布式大脑模式的人表达预测选择调节对超出刺激预测值的特定刺激的反应情绪的强度或自我报告。这些结果证明了大脑对厌恶刺激反应的变异性的行为相关性，并提供了一个利用这种变异性来预测行为的模型。
Deciding to control emotional responses is a fundamental means of responding to environmental challenges, but little is known about the neural mechanisms that predict the outcome of such decisions. We used fMRI to test whether human brain responses during initial viewing of negative images could be used to predict decisions to regulate affective responses to those images. Our results revealed the following: (1) decisions to regulate were more frequent in individuals exhibiting higher average levels of activity within the amygdala and regions of PFC known a priori to be involved in the cognitive control of emotion and (2) within-person expression of a distributed brain pattern associated with regulating emotion predicted choosing to regulate responses to particular stimuli beyond the predictive value of stimulus intensity or self-reports of emotion. These results demonstrate the behavioral relevance of variability in brain responses to aversive stimuli and provide a model that leverages this variability to predict behavior.
