Empathy is one such social-cognitive capacity that undergoes age-related change. C urrently, however, not well understood is the structural and functional neurocircuitry underlying age-related differences in empathy. This study aimed to delineate brain structural and functional networks that subserve affective empathic response in younger and older adults using a modified version of the Multifaceted Empathy Task to both positive and negative emotions. Combining multimodal neuroimaging with multivariate partial least square analysis resulted in two novel findings in older but not younger adults: faster empathic responding to negative emotions was related to greater fractional anisotropy of the anterior cingulum and greater functional activity of the anterior cingulate network; however, empathic responding to positive emotions was related to greater fractional anisotropy of the posterior cingulum and greater functional activity of the posterior cingulate network. Such differentiation of structural and functional networks might have critical implications for prosocial behavior and social connections among older adults.
同理心就是这样一种会随着年龄变化的社会认知能力。然而,目前对于同理心年龄差异背后的结构和功能神经回路还没有很好的理解。本研究旨在通过使用多维度同理心任务的修改版本,对年轻人和老年人的积极和消极情绪进行情感同理心反应,来描绘出支持情感同理心反应的大脑结构和功能网络。将多模态神经成像与多变量偏最小二乘分析相结合,在老年人而非年轻人中得出了两个新发现:对负面情绪更快的同理心反应与前扣带束更大的各向异性分数以及前扣带网络更大的功能活动有关;然而,对正面情绪的同理心反应与后扣带束更大的各向异性分数以及后扣带网络更大的功能活动有关。这种结构和功能网络的差异可能对老年人的亲社会行为和社会联系具有关键意义。
