Abstract
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 (BF10 > 10); remaining correlations showed substantial evidence (10 > BF10 > 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.
Highlights
Assessment of brain activity during the resting-state in clinical and cognitive neuroscience allows to shed some light on brain’s self-organization properties and how these patterns affect functioning and experiencing [1]
We evaluated the association between biologically defined microstate activity of other classes and different subjective experiences and emotions occurring during the resting-state session as measured with Amsterdam Resting-State Questionnaire (ARSQ)
One topography displayed posterior activity and matched microstate F reported in studies by [21,22,46], microstate E reported in studies by [47,48,49] and microstate C0 reported in study [50] and was further labeled as microstate F
Summary
Assessment of brain activity during the resting-state in clinical and cognitive neuroscience allows to shed some light on brain’s self-organization properties and how these patterns affect functioning and experiencing [1]. The ARSQ covers ten resting-state cognition domains: Discontinuity of Mind (DoM), Theory of Mind (ToM), Self, Planning, Sleepiness, Comfort, Somatic Awareness (SA), Health Concerns (HC), Visual Thought (Vis) and Verbal Thought (VT) [12,13]. This tool has been successfully applied in neuroimaging studies, including those using EEG [14,15,16,17,18,19]
