Cardiac and Brain Activity during a Stress Recall Task: Does It Change after a Mindfulness-Based Stress Reduction Intervention?

The aim was to examine effects of Mindfulness-Based Stress Reduction (MBSR) on affective, cardiac and cortical domains during recall of a recent stressful episode. Compared to controls, MBSR participants showed smaller stress-related response in the cortical beta power band, but not in heart rate variability after the intervention.
