RATIONALE
The resting-state paradigm is frequently applied in electroencephalography (EEG) research; however, it is associated with the inability to control participants' thoughts. To quantify subjects' subjective experiences at rest, the Amsterdam Resting-State Questionnaire (ARSQ) was introduced covering ten dimensions of mind wandering. We aimed to estimate associations between subjective experiences and resting-state microstates of EEG.
METHODS
5 min resting-state EEG data of 197 subjects was used to evaluate temporal properties of seven microstate classes. Bayesian correlation approach was implemented to assess associations between ARSQ domains assessed after resting and parameters of microstates.
RESULTS
Several associations between Comfort, Self and Somatic Awareness domains and temporal properties of neuroelectric microstates were revealed. The positive correlation between Comfort and duration of microstates E showed the strongest evidence (BF > 10); remaining correlations showed substantial evidence (10 > BF > 3).
CONCLUSION
Our study indicates the relevance of assessments of spontaneous thought occurring during the resting-state for the understanding of the intrinsic brain activity reflected in microstates.
原理
静息态范式在脑电图（EEG）研究中经常被应用；然而，它存在无法控制参与者思维的问题。为了量化受试者在静息状态下的主观体验，引入了涵盖思维游荡十个维度的阿姆斯特丹静息状态问卷（ARSQ）。我们旨在估计主观体验与EEG静息态微状态之间的关联。
方法
使用197名受试者的5分钟静息态EEG数据来评估七个微状态类别的时间特性。采用贝叶斯相关方法来评估静息后评估的ARSQ领域与微状态参数之间的关联。
结果
揭示了舒适、自我和躯体意识领域与神经电微状态的时间特性之间的几种关联。舒适与微状态E持续时间之间的正相关显示出最强的证据（贝叶斯因子>10）；其余相关性显示出充分的证据（10>贝叶斯因子>3）。
结论
我们的研究表明，评估静息状态下发生的自发思维对于理解微状态中反映的内在大脑活动具有相关性。
