Increased neurocardiological interplay after mindfulness meditation: a brain oscillation-based approach
Frontiers in Human Neuroscience June 19, 2023 Junling Gao, R. Sun, Hang Kin Leung et al.
After 8 weeks of Mindfulness Based Stress Reduction (MBSR) training, the correlation between alpha brain wave frequency and heart coherence increased significantly in the middle frontal and bilateral temporal regions. Alpha coherence and heart coherence showed similar changes, but alpha peak power did not. Standard spectrum analysis alone showed no difference before and after training. Individual alpha peak frequency is relatively stable, and its interplay with cardiac activity may be a more sensitive measure of brain-heart connection than power spectrum. This preliminary study involved eleven participants aged 28–52 years.
