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大学生样本（N = 68）中调查身体形状问题与身体图像网络中的脑电图（EEG）功能连接之间的关联。在静息状态下 5 分钟记录 EEG。所有参与者都被要求完成自我报告措施，评估某些心理病理维度（即，体型问题、抑郁、焦虑、强迫症状）。EEG 分析是通过精确的低分辨率电磁断层扫描软件 (eLORETA) 进行的。我们的结果表明，体型问题与左右前额叶皮层 (PFC) 之间的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 EEG 模式与体型问题独立相关。这一发现似乎表明左右 PFC 之间增加的 EEG 伽玛连接可能是一种相关的神经生理学改变，涉及对一个人的身体功能失调的担忧的发展和/或维持。
