Gender differences in emotion regulation (ER) have been postulated, yet their neural basis remains poorly understood. The goal of this study was to investigate this issue from a functional connectivity (FC) perspective. Utilizing a region of interest (ROI) analysis, we investigated whether men and women (N = 48) differed in their FC pattern while viewing versus regulating negative emotion induced by highly salient pictures, and whether this pattern related to their self-reported negative affect and suppression success. Despite women reporting more negative affect, both genders had comparable suppression success. Moreover, differences emerged between men and women's FC patterns. During the regulation of negative emotion, better suppression in women was associated with stronger FC within a cingulo-opercular network, while men exhibited stronger FC within posterior regions of the ventral attentional network. We conclude that due to their propensity for higher emotional reactivity, women may employ a frontal top-down control network to downregulate negative emotion, while men may redirect attention away from the negative stimulus by using posterior regions of the ventral attention network. The findings may have significant implications for understanding women's vulnerability for developing affective disorders and developing targeted individualized treatment.

情绪调节过程中功能连接的性别差异

情绪调节(ER)的性别差异已被假定,但其神经基础仍然知之甚少。这项研究的目的是从功能连接(FC)的角度调查此问题。利用兴趣区域(ROI)分析,我们调查了男性和女性(N = 48)在观看和调节由高度显着图片引起的负面情绪时,其FC模式是否有所不同,以及这种模式是否与他们自我报告的负面影响有关和压制成功。尽管妇女报告了更多的负面影响,但两性的镇压成功率相当。此外,男女FC模式之间也出现了差异。在调节负面情绪的过程中,女性更好的压制与扣带-耳蜗网络中更强的FC相关,而男性在腹侧注意网络的后部区域表现出更强的FC。我们得出的结论是,由于女性倾向于较高的情绪反应性,因此女性可以使用正面自上而下的控制网络来下调负面情绪,而男性可以通过使用腹侧注意力网络的后部区域将注意力从负面刺激中转移出来。该发现可能对理解妇女在发展情感障碍和开发有针对性的个体化治疗方面的脆弱性具有重要意义。而男性则可以通过腹侧注意网络的后部区域将注意力从负面刺激转移开。该发现可能对理解妇女在发展情感障碍和开发有针对性的个体化治疗方面的脆弱性具有重要意义。而男性则可以通过腹侧注意网络的后部区域将注意力从负面刺激转移开。该发现可能对理解妇女在发展情感障碍和开发有针对性的个体化治疗方面的脆弱性具有重要意义。
