Emotion regulation allows humans to successfully modulate their reactions to life events. Whether regulation strategies may alter brain oscillatory activity and how they are influenced by format and emotional dimensions is still under debate. We investigated oscillatory brain dynamics during the implementation of the strategy of Distancing and during the regulation of the emotions elicited by neutral and unpleasant pictures and, for the first time, words. When implementing the strategy, an early increase in theta band in posterior regions was observed (Effect of Strategy). We interpret this effect as a marker of emotion regulation, and we suggest an integrative framework of the role of theta on regulatory processes. When regulating the emotional impact elicited by stimuli, a decrease in the theta and beta bands in posterior regions for pictures, but not for words, was observed (Effect of Regulation). Behaviorally, the Effect of Regulation was evident for both pictures and words and more pronounced for Valence than for Arousal. These results contribute to better understand the neural and behavioral features of Distancing (both Effect of Strategy and of Regulation), and open up the possibility to clarify which strategy works better to modulate specific stimulus types and emotional dimensions.

调入正确的频率：远离令人不快的图像和文字引起的情绪时，Theta会发生变化
情绪调节使人类能够成功地调节其对生活事件的反应。调节策略是否可以改变大脑的振荡活动以及它们如何受到形式和情感维度的影响仍在争论中。我们研究了在实施“距离”策略时以及在调节中性和令人不快的图片以及首次引起的情绪引起的情绪波动时大脑的动态变化。实施该策略时，观察到后区theta谱带提前增大（该策略的效果）。我们将这种效应解释为情绪调节的标志，并提出了theta在调节过程中作用的综合框架。调节刺激引起的情感影响时，图片后部的theta和beta谱带会减少，但观察到的不是言语（法规的效果）。从行为上讲，调节的效果在图片和文字上都很明显，对价的影响比对唤醒的影响更为明显。这些结果有助于更好地了解距离分离的神经和行为特征（策略和调节的效果），并为阐明哪种策略更好地调节特定刺激类型和情绪维度提供了可能性。
