Abstract

There is a growing appreciation for the health benefits of giving support, though variability in such behavior exists. Based on the possibility that the dorsomedial (DMPFC) default network subsystem is associated with social thinking and behavior, integrity of this subsystem may facilitate giving support to others. The current study tested associations between DMPFC subsystem connectivity at rest and tendencies related to giving support. During a functional magnetic resonance imaging session, 45 participants completed an emotional social cues task, a resting-state scan and self-report measures of social support. Supportive behavior during the month following the scan was also assessed. Greater DMPFC subsystem connectivity at rest was associated with greater support giving (though not receiving or perceiving support) at the time of the scan and one month later. Results held after adjusting for extraversion. In addition, greater resting-state DMPFC subsystem connectivity was associated with attenuated dorsal anterior cingulate cortex, anterior insula and amygdala activity to others’ negative emotional social cues, suggesting that DMPFC subsystem integrity at rest is also associated with the dampened withdrawal response proposed to facilitate care for others in need. Together, results begin to hint at an additional role for the ‘default’ social brain: giving support to others.

休息状态连接和给予社会支持方面的个体差异：对健康的影响。

摘要

提供支持对健康的好处日益受到重视，尽管这种行为存在差异。基于背靠背（DMPFC）默认网络子系统与社会思维和行为相关联的可能性，该子系统的完整性可以有助于为他人提供支持。当前的研究测试了DMPFC子系统静态连接与提供支持的趋势之间的关联。在功能性磁共振成像会议中，有45位参与者完成了情感社交线索任务，休息状态扫描和社交支持的自我报告措施。还评估了扫描后一个月内的支持行为。扫描时和一个月后，更高的DMPFC子系统静态连接性与提供更大的支持（尽管没有获得或感知到支持）相关。调整外推后保留的结果。此外，较高的静止状态DMPFC子系统连通性与其他负面情绪社交线索的背侧扣带回前皮层，前岛岛和杏仁核活动减弱有关，这表明DMPFC子系统在休息时的完整性也与拟议的减退反应有关。照顾有需要的人。总之，结果开始暗示“默认”社交大脑的其他作用：给予他人支持。较高的静息状态DMPFC子系统连通性与其他负面情绪社交线索的背侧扣带回前皮，前岛岛和杏仁核活动减弱有关，这表明DMPFC子系统在静息状态下的完整性也与为促进对他人的照料而提出的减退性戒断反应有关。有需要。总之，结果开始暗示“默认”社交大脑的其他作用：给予他人支持。较高的静息状态DMPFC子系统连通性与其他负面情绪社交线索的背侧扣带回前皮，前岛岛和杏仁核活动减弱有关，这表明DMPFC子系统在静息状态下的完整性也与为促进对他人的照料而提出的减退性戒断反应有关。有需要。总之，结果开始暗示“默认”社交大脑的其他作用：给予他人支持。
