本研究利用扩散张量成像技术,对孤独感的个体差异进行了初步研究。据我们所知,这是第一个初步的扩散张量成像证据,表明腹侧注意力网络,通常由注意力重新定向激活,也与孤独有关。图像重建结果表明,显着降低分数各向异性的白色物质纤维和相关节点的腹侧注意力网络是高度相关的孤独等级增加。通过提供结构层面的证据,我们的研究结果表明,注意力重新定向能力在形成个体的孤独感中起着重要作用。
A pilot study was carried out to determine individual differences in perceived loneliness using diffusion tensor imaging. To the best of our knowledge, this is the first preliminary diffusion tensor imaging evidence that the ventral attention network, generally activated by attentional reorienting, was also related to loneliness. Image reconstruction results indicated significantly decreased fractional anisotropy of white matter fibers and that associated nodes of the ventral attention network are highly correlated with increased loneliness ratings. By providing evidence on the structural level, our findings suggested that attention-reorienting capabilities play an important role in shaping an individual’s loneliness.
