摘要

引言:低自尊是导致精神疾病的一个众所周知的危险因素。神经影像学研究已经确定了默认模式网络(DMN)和自尊水平之间功能关联的证据。然而，目前尚不清楚特质自尊与构成DMN的结构之间是否存在类似的关联。本研究旨在探讨DMN相关脑结构与特质自尊的关系。方法:获取75名健康受试者的3T结构磁共振成像(MRI)数据，通过基于体素的形态测量(VBM)检测与Rosenberg自尊评分相关的解剖区域。结果:我们发现自尊与右侧颞顶交界处/下顶叶(ba39)、楔前叶/扣带回背皮层(ba31)皮质中线区域、扣带回吻侧和背前皮层(ba32)的区域灰质体积呈正相关。结论:本研究的结果支持功能磁共振成像的研究结果，表明自尊水平与DMN相关。进一步的神经影像学研究应该考虑在执行与自尊相关的功能时默认模式网络的功能和结构耦合。

The Reflection of Self-Esteem on the Brain Structure: A Voxel Based Morphometry Study in Healthy Young Adults.

Introduction: Low self-esteem is a known risk factor for mental illnesses. Neuroimaging studies have identified evidence for a functional association between default mode network (DMN) and self-esteem levels. However, it is not clear whether there is a similar association between trait self-esteem and the structures composing DMN. This study aimed to investigate the relationship between the DMN associated brain structures and trait self-esteem.

Methods: We obtained 3T structural magnetic resonance imaging (MRI) data of 75 healthy subjects and detected anatomical regions correlated with their Rosenberg Self-Esteem scores via voxel-based morphometry (VBM).

Results: We found positive associations between self-esteem and regional grey matter volumes in the right temporoparietal junction/inferior parietal lobule (BA 39), cortical midline regions at precuneus/dorsal cingulate cortex (BA 31), rostral and dorsal anterior cingulate cortices (BA 32).

Conclusion: The results of the current study support the fMRI studies suggesting self-esteem levels associated with DMN. Further neuroimaging studies should consider the functional and structural coupling of the default mode network during the execution of the functions related to self-esteem.

期刊介绍： Archives of Neuropsychiatry (Arch Neuropsychiatry) is the official journal of the Turkish Neuropsychiatric Society. It is published quarterly, and four editions annually constitute a volume. Archives of Neuropsychiatry is a peer reviewed scientific journal that publishes articles on psychiatry, neurology, and behavioural sciences. Both clinical and basic science contributions are welcomed. Submissions that address topics in the interface of neurology and psychiatry are encouraged. The content covers original research articles, reviews, letters to the editor, and case reports.
