Cognitive reappraisal and expressive suppression, two major emotion regulation strategies, are differentially related to emotional well-being. The aim of this study was to test the association of individual differences in these two emotion regulation strategies with gray matter volume of brain regions that have been shown to be involved in the regulation of emotions. Based on high-resolution magnetic resonance images of 96 young adults voxel-based morphometry was used to analyze the gray matter volumes of the a priori regions of interest, including amygdala, insula, dorsal anterior cingulate and paracingulate cortex, medial and lateral prefrontal cortex (PFC) and their association with cognitive reappraisal and expressive suppression usage as well as neuroticism. A positive association of cognitive reappraisal with right and tendentially left amygdala volume and of neuroticism with left amygdala volume (marginally significant) was found. Expressive suppression was related to dorsal anterior cingulate/paracingulate cortex and medial PFC gray matter volume. The results of this study emphasize the important role of the amygdala in individual differences in cognitive reappraisal usage as well as neuroticism. Additionally, the association of expressive suppression usage with larger volumes of the medial PFC and dorsal anterior/paracingulate cortex underpins the role of these regions in regulating emotion-expressive behavior.
认知重评和表达抑制是两种主要的情绪调节策略，它们与情绪幸福感的关系有所不同。本研究的目的是检验这两种情绪调节策略的个体差异与已被证明参与情绪调节的脑区灰质体积之间的关联。基于96名年轻人的高分辨率磁共振图像，采用基于体素的形态测量法分析了先验感兴趣区域的灰质体积，这些区域包括杏仁核、脑岛、背侧前扣带回和扣带旁皮质、内侧和外侧前额叶皮质（PFC），以及它们与认知重评和表达抑制的使用情况以及神经质的关联。研究发现，认知重评与右侧以及倾向于左侧的杏仁核体积呈正相关，神经质与左侧杏仁核体积呈正相关（边缘显著）。表达抑制与背侧前扣带回/扣带旁皮质以及内侧PFC的灰质体积有关。本研究结果强调了杏仁核在认知重评使用的个体差异以及神经质方面的重要作用。此外，表达抑制的使用与内侧PFC和背侧前/扣带旁皮质较大体积之间的关联，支持了这些区域在调节情绪表达行为中的作用。
