近年来，大量的神经影像学研究对认知再评估（cognitive reappraisal）进行了研究。认知再评估是一种情绪调节策略，涉及改变一个人对刺激的思考方式，以改变其情感影响。现有的模型普遍认为，重新评估调动了额叶和顶叶控制区域来调节杏仁核中的情绪反应，但他们对如何完成这一过程提出了不同的看法。一种观点认为，控制区域涉及腹内侧前额叶皮层（vmPFC），这是一个与恐惧消退相关的区域，反过来调节杏仁核的反应。另一种观点是，控制区域调节外侧颞叶皮层的语义表征，间接影响杏仁核中与情绪相关的反应。此外，虽然先前的研究强调了杏仁核，但重新评估是否会影响其他涉及情绪反应的区域仍然未知。为了解决这些问题，我们对48项重新评估的神经影像学研究进行了荟萃分析，其中大多数涉及负面情绪的下调。重新评价一致：(1)激活了认知控制区和外侧颞叶皮层，但没有激活vmPFC；(2)调节了双侧杏仁核，但没有调节其他脑区。这表明，重新评价涉及使用认知控制来调节情绪刺激的语义表征，而这些改变的表征反过来减弱杏仁核的活动。
In recent years, an explosion of neuroimaging studies has examined cognitive reappraisal, an emotion regulation strategy that involves changing the way one thinks about a stimulus in order to change its affective impact. Existing models broadly agree that reappraisal recruits frontal and parietal control regions to modulate emotional responding in the amygdala, but they offer competing visions of how this is accomplished. One view holds that control regions engage ventromedial prefrontal cortex (vmPFC), an area associated with fear extinction, that in turn modulates amygdala responses. An alternative view is that control regions modulate semantic representations in lateral temporal cortex that indirectly influence emotion-related responses in the amygdala. Furthermore, while previous work has emphasized the amygdala, whether reappraisal influences other regions implicated in emotional responding remains unknown. To resolve these questions, we performed a meta-analysis of 48 neuroimaging studies of reappraisal, most involving downregulation of negative affect. Reappraisal consistently 1) activated cognitive control regions and lateral temporal cortex, but not vmPFC, and 2) modulated the bilateral amygdala, but no other brain regions. This suggests that reappraisal involves the use of cognitive control to modulate semantic representations of an emotional stimulus, and these altered representations in turn attenuate activity in the amygdala.
