Abstract

Background: Living a happy and meaningful life is an eternal topic in positive psychology, which is crucial for individuals' physical and mental health as well as social functioning. Well-being can be subdivided into pleasure attainment related hedonic well-being or emotional well-being, and self-actualization related eudaimonic well-being or psychological well-being plus social well-being. Previous studies have mostly focused on human brain morphological and functional mechanisms underlying different dimensions of well-being, but no study explored brain network mechanisms of well-being, especially in terms of topological properties of human brain morphological similarity network.

Methods: Therefore, in the study, we collected 65 datasets including magnetic resonance imaging (MRI) and well-being data, and constructed human brain morphological network based on morphological distribution similarity of cortical thickness to explore the correlations between topological properties including network efficiency and centrality and different dimensions of well-being.

Results: We found emotional well-being was negatively correlated with betweenness centrality in the visual network but positively correlated with eigenvector centrality in the precentral sulcus, while the total score of well-being was positively correlated with local efficiency in the posterior cingulate cortex of cortical thickness network.

Conclusions: Our findings demonstrated that different dimensions of well-being corresponded to different cortical hierarchies: hedonic well-being was involved in more preliminary cognitive processing stages including perceptual and attentional information processing, while hedonic and eudaimonic well-being might share common morphological similarity network mechanisms in the subsequent advanced cognitive processing stages.

Abstract Image

幸福感与人脑皮层厚度网络拓扑结构有关。
背景:幸福而有意义的生活是积极心理学中永恒的主题,对个体的身心健康和社会功能至关重要。幸福感可以细分为与快乐获得相关的享乐幸福感或情感幸福感,以及与自我实现相关的生理幸福感或心理幸福感加社会幸福感。先前的研究大多集中在不同维度幸福感背后的人脑形态和功能机制上,但没有研究探讨幸福感的脑网络机制,特别是在人脑形态相似性网络的拓扑特性方面。方法:因此,在本研究中,我们收集了65个数据集,包括磁共振成像(MRI)和健康数据,并基于皮层厚度的形态学分布相似性构建了人脑形态学网络,探讨网络效率、中心性等拓扑特性与不同幸福维度之间的相关性幸福感总分与皮层厚度网络后扣带皮层的局部效率呈正相关。结论:我们的研究结果表明,幸福感的不同维度对应于不同的皮层层次:享乐幸福感参与了更多的初步认知处理阶段,包括感知和注意信息处理,而享乐幸福感和日常幸福感在随后的高级认知加工阶段可能共享共同的形态相似性网络机制。

期刊介绍: A well-established journal in the field of behavioral and cognitive neuroscience, Behavioral and Brain Functions welcomes manuscripts which provide insight into the neurobiological mechanisms underlying behavior and brain function, or dysfunction. The journal gives priority to manuscripts that combine both neurobiology and behavior in a non-clinical manner.
