In contrast, spectrum analysis alone did not show difference before and after MBSR training.Ĭonclusion: The brain works in rhythmic oscillation, and this rhythmic connection becomes more coherent with cardiac activity after 8 weeks of MBSR training. The correlation between alpha coherence and heart coherence had similar changes, while alpha peak power did not reflect such changes. Results: After 8 weeks of MBSR training, the correlation between APF and HC increased significantly in the middle frontal region and bilateral temporal regions. Heart coherence (HC) and heartbeat evoked potential (HEP) were calculated for further correlation analysis. FMRIB toolbox was used to extract the ECG data. EEGLAB was used to analyze the alpha band (8–12 Hz) power, alpha peak frequency (APF), peak power and coherence. EEG and ECG data of two states of mindful breathing and rest, both eye-closed, were recorded before and after the training. Methods: Eleven participants (28–52 years) attended 8 weeks of Mindfulness Based Stress Reduction (MBSR) training. We hypothesize that mindfully breathing can make the brain and heart activities more coherent in terms of increased connectivity between the electroencephalogram (EEG) and electrocardiogram (ECG) signals. 4Department of Psychology, HKU School of Professional and Continuing Education, Hong Kong, Hong Kong SAR, Chinaīackground: Brain oscillations facilitate interaction within the brain network and between the brain and heart activities, and the alpha wave, as a prominent brain oscillation, plays a major role in these coherent activities.3Singapore-ETH Centre, Future Resilient Systems Programme, Singapore, Singapore.2Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, Hong Kong SAR, China.1Buddhist Practices and Counselling Science Lab, Centre of Buddhist Studies, The University of Hong Kong, Hong Kong, Hong Kong SAR, China.Junling Gao 1 Rui Sun 2 Hang Kin Leung 1 Adam Roberts 3 Bonnie Wai Yan Wu 1 Eric W.
