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.
性别在情绪调节(ER)方面存在差异,但其神经基础仍知之甚少。本研究旨在从功能连接(FC)的角度探讨这个问题。我们利用感兴趣区域(ROI)分析,研究了男性和女性(N=48)在观看和调节高显著性图片引起的负性情绪时,其 FC 模式是否存在差异,以及这种模式是否与他们的自我报告的负性情绪和抑制成功相关。尽管女性报告的负性情绪更多,但两性的抑制成功相当。此外,男女的 FC 模式存在差异。在调节负性情绪时,女性的抑制效果越好,扣带回-顶叶网络内的 FC 越强,而男性则表现出更强的腹侧注意网络的后部区域的 FC。我们的结论是,由于女性情绪反应性较高,她们可能会利用额顶控制网络来下调负性情绪,而男性可能会通过使用腹侧注意网络的后部区域来转移对负性刺激的注意力。这些发现可能对理解女性易患情感障碍的原因以及制定有针对性的个体化治疗方案具有重要意义。
