Mindfulness as a dispositional trait is linked to specific patterns of spontaneous brain network dynamics. After an 8-week mindfulness-based stress reduction (MBSR) training, participants showed significantly higher mindfulness scores on the Five Facet Mindfulness Questionnaire (FFMQ), particularly in observing and non-reactivity, compared to a waitlist control group. Resting-state EEG microstate analysis revealed four classes (A-D). The MBSR group had lower duration, occurrence, and coverage of microstate C, and these parameters negatively correlated with non-reactivity scores. Microstate A occurrence negatively correlated with total FFMQ score. Self-reports indicated better sensory-affective integration of auditory interferences in the MBSR group. The findings suggest that microstate C dynamics specifically underlie the non-reactivity facet of mindfulness, supporting further use of microstates to evaluate mindfulness-based interventions.
