Emotion dysregulation is a key feature of mood and anxiety disorders. Many of these disorders also involve volumetric reductions in brain regions implicated in emotion regulation, including the dorsal anterior cingulate cortex (dACC). Investigating this relationship in healthy individuals may clarify the link between emotion regulation and volumetric reductions in this key brain region. High-resolution anatomical MRI images were used to calculate dACC volumes in 50 healthy female subjects. Trait measures of emotion regulation (cognitive reappraisal and expressive suppression) and negative affect were also obtained. As predicted, cognitive reappraisal was positively related to dACC volume, but not the volume of a control region, the ventral ACC. Expressive suppression, negative affect, and age were not related to dACC volume. These findings indicate that individual differences in cognitive reappraisal are related to individual differences in dACC volume in healthy participants.
情绪失调是心境和焦虑障碍的一个主要特征。这些障碍中的许多还涉及到与情绪调节相关的脑区(包括背侧前扣带皮层[dACC])的体积减少。在健康个体中研究这种关系可能可以阐明情绪调节与该关键脑区体积减少之间的联系。使用高分辨率解剖 MRI 图像计算了 50 名健康女性被试的 dACC 体积。还获得了情绪调节(认知重评和表达抑制)和负性情绪的特质测量。正如预测的那样,认知重评与 dACC 体积呈正相关,但与对照区域(腹侧前扣带皮层)的体积无关。表达抑制、负性情绪和年龄与 dACC 体积无关。这些发现表明,健康参与者的认知重评个体差异与 dACC 体积的个体差异有关。
