Meditation techniques, including a martial arts-based form combining focused attention and mindful acceptance, lower activation in default mode network (DMN) regions—the medial frontal cortex, precuneus, and posterior cingulate cortex—in children with cancer when they watch distress-inducing video clips, compared to passively viewing the clips. Meditation may modulate DMN activity more effectively than distraction, a non-meditation emotion regulation strategy. No differences in self-reported distress ratings appeared between conditions. The findings suggest martial arts-based meditation alters negative self-referential processing linked to the DMN, with potential applications for managing pediatric pain and negative emotion.
In children and adolescents aged 6-17, trait mindfulness is linked to dynamic, time-varying patterns of brain connectivity rather than to static connectivity. More mindful youth transitioned more frequently between different brain states, spent less time in a particular connectivity state, and showed reduced connectivity between salience/emotion and central executive networks in one state. The number of state transitions mediated the link between higher mindfulness and lower anxiety, suggesting a neural mechanism for mindfulness benefits on psychological health in youth.
