情绪是我们精神生活中不可或缺的一部分。情绪调节是指影响情绪产生、体验和表达的过程。情绪调节的策略有很多种，这些策略在日常生活中得到了广泛的应用，并且已经被认知神经科学所研究。分心会把注意力引向次要任务。重新解释是认知重新评价的一种变体，通过改变情感刺激的意义来发挥作用。另一种重新评价策略是脱离情绪刺激，从而降低其个人相关性。表达抑制改变对情绪刺激的行为或生理反应。这四种策略在情绪调节成功方面并不同样有效，并且已被证明部分依赖于不同的神经系统。在这里，我们第一次比较这些典型的策略直接在一个共同的功能性磁共振成像（fMRI）范式下调的负面情绪的神经机制。我们的研究结果表明，其中三个策略（分离，表达抑制和分心）联合增加大脑激活的右前额叶-顶叶调节网络，并显着减少激活的左杏仁核。与其他调节策略相比，重新解释特别招募了一个不同的控制网络，包括左腹外侧前额叶皮层和眶额回，并且在杏仁核的下调中无效。我们的结论是，分离，分心和表达抑制招募非常相似的情绪调节网络，而重新解释是与激活一个质的不同的网络，使这种调节策略一个特殊的。值得注意的是，重新解释也被证明是神经方面最有效的策略，如杏仁核激活的下调所测量的。(C)2014 Elsevier Inc.

Emotions are an indispensable part of our mental life. The term emotion regulation refers to those processes that influence the generation, the experience and the expression of emotions. There is a great variety of strategies to regulate emotions efficiently, which are used in daily life and that have been investigated by cognitive neuroscience. Distraction guides attention to a secondary task. Reinterpretation, a variant of cognitive reappraisal, works by changing the meaning of an emotional stimulus. Detachment, another reappraisal strategy, refers to distancing oneself from an emotional stimulus, thereby reducing its personal relevance. Expressive Suppression modifies the behavioral or physiological response to an emotional stimulus. These four strategies are not equally effective in terms of emotion regulation success and have been shown to partly rely on different neuronal systems. Here, we compare for the first time the neural mechanisms of these typical strategies directly in a common functional magnetic resonance imaging (fMRI) paradigm of downregulation of negative emotions. Our results indicate that three of those strategies (Detachment, Expressive Suppression and Distraction) conjointly increase brain activation in a right prefronto-parietal regulation network and significantly reduce activation of the left amygdala. Compared to the other regulation strategies, Reinterpretation specifically recruited a different control network comprising left ventrolateral prefrontal cortex and orbitofrontal gyrus and was not effective in downregulation of the amygdala. We conclude that Detachment, Distraction and Expressive Suppression recruit very similar emotion regulation networks, whereas Reinterpretation is associated with activation of a qualitatively different network, making this regulation strategy a special one. Notably, Reinterpretation also proved to be the least effective strategy in neural terms, as measured by downregulation of amygdala activation. (C) 2014 Elsevier Inc. All rights reserved.
