The main aim of the present study was to investigate the association between body shape concerns and electroencephalography (EEG) functional connectivity within body image network in a sample of university students (N = 68). EEG was recorded during 5 min of resting state. All participants were asked to complete self-report measures assessing certain psychopathological dimensions (i.e., body shape concerns, depression, anxiety, obsessive-compulsive symptoms). EEG analyses were conducted by means of the exact low-resolution electromagnetic tomography software (eLORETA). Our results showed that body shape concerns were positively associated with increased gamma functional connectivity between the left and right prefrontal cortex (PFC). Furthermore, our data revealed that this EEG pattern was independently associated with body shape concerns after controlling for potential socio-demographic and clinical confounding variables. This finding seems to suggest that increased EEG gamma connectivity between the left and right PFC might be a relevant neurophysiological alteration involved in the development and/or maintenance of dysfunctional concerns about one's body.
本研究的主要目的是在一组大学生样本（N = 68）中，调查身体形象关注与身体意象网络内脑电图（EEG）功能连接之间的关联。在静息状态下记录5分钟的脑电图。所有参与者都被要求完成自我报告测量，以评估某些精神病理学维度（即身体形象关注、抑郁、焦虑、强迫症状）。脑电图分析通过精确低分辨率电磁断层扫描软件（eLORETA）进行。我们的结果表明，身体形象关注与左右前额叶皮质（PFC）之间伽马功能连接增加呈正相关。此外，我们的数据显示，在控制了潜在的社会人口统计学和临床混杂变量后，这种脑电图模式与身体形象关注独立相关。这一发现似乎表明，左右前额叶皮质之间脑电图伽马连接增加可能是参与对自身身体功能失调关注的发展和/或维持的一种相关神经生理改变。
