情绪调节障碍是心境和焦虑障碍的一个重要特征。这些疾病中的许多还涉及与情绪调节有关的大脑区域的体积减小，包括背侧前扣带皮层（dACC）。在健康个体中调查这种关系可能会澄清情绪调节和这一关键大脑区域体积减少之间的联系。使用高分辨率解剖MRI图像计算50名健康女性受试者的dACC体积。情绪调节（认知重评和表达抑制）和负面情绪的特质措施也得到了。正如预测的那样，认知再评价与dACC体积呈正相关，但不与控制区域（腹侧ACC）的体积呈正相关。表达抑制、负面影响和年龄与dACC体积无关。这些研究结果表明，认知重新评价的个体差异与健康受试者dACC体积的个体差异有关。
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.
