调节情绪反应最有效的策略之一是认知重新评估。虽然先前的工作在描述重新评估的神经机制和行为结果方面取得了很大进展，但调节如何作为情绪强度的函数而变化的关键问题仍然没有得到解决。我们使用功能性磁共振成像（fMRI）比较了高强度和低强度情绪反应重评价的行为和神经相关性。我们发现，成功地重新评估高强度和低强度情绪依赖于背内侧（dmPFC）以及左背外侧（dlPFC）和腹外侧（vlPFC）前额叶皮层的募集。然而，高强度情绪的重新评价更强烈地激活了左侧dlPFC，此外，激活了未被低强度重新评价招募的右侧外侧和背内侧PFC区域。与高强度情绪相比，在重新评估低强度情绪时，没有大脑区域被更强烈地调动起来。综上所述，这些结果表明，重新评估高强度情绪需要更多的认知资源，前额叶招募的数量和质量差异证明了这一点。这些数据对理解特定的PFC系统如何以及何时需要调节不同类型的情绪反应具有重要意义。
One of the most effective strategies for regulating emotional responses is cognitive reappraisal. While prior work has made great strides in characterizing reappraisal's neural mechanisms and behavioral outcomes, the key issue of how regulation varies as a function of emotional intensity remains unaddressed. We compared the behavioral and neural correlates of reappraisal of high- and low-intensity emotional responses using functional magnetic resonance imaging (fMRI). We found that successful reappraisal of both high- and low-intensity emotions depends upon recruitment of dorsomedial (dmPFC) as well as left dorsolateral (dlPFC) and ventrolateral (vlPFC) prefrontal cortex. However, reappraisal of high-intensity emotions more strongly activated left dlPFC, and in addition, activated right lateral and dorsomedial PFC regions not recruited by low-intensity reappraisal. No brain regions were more strongly recruited during reappraisal of low when compared with high-intensity emotions. Taken together, these results suggest that reappraisal of high-intensity emotion requires greater cognitive resources as evidenced by quantitative and qualitative differences in prefrontal recruitment. These data have implications for understanding how and when specific PFC systems are needed to regulate different types of emotional responses.
