שימוש באנטרופיה Wavelet כדי להדגים כיצד תרגול תשומת לב מגביר את התיאום בין פעילות מוחית לא סדירה ופעילות לב Hin Hung Sik1, Junling Gao1,2, Jicong Fan1, Bonnie Wai Yan Wu1, Hang Kin Leung1, Yeung Sam Hung2 1Centre of Buddhist Studies, The University of Hong Kong, 2Department of Electrical and Electronic Engineering, The University of Hong Kong כתב יד זה מתאר כיצד להשתמש במדד אנטרופיה אדוה לנתח צפיפות גבוהה electroencephalography (EEG) ו אלקטרוקרדיוגרפיה (ECG) נתונים. אנו מראים כי אי סדירות של הפעילות המוחית והלבנית הפכה מתואמת יותר במהלך תרגול הפחתת מתח המבוסס על תשומת לב.

Entrainment of Chaotic Activities in Brain and Heart During MBSR Mindfulness Training Neuroscience Letters. Mar, 2016 | Pubmed ID: 26784361 The activities of the brain and the heart are dynamic, chaotic, and possibly intrinsically coordinated. This study aims to investigate the effect of Mindfulness-Based Stress Reduction (MBSR) program on the chaoticity of electronic activities of the brain and the heart, and to explore their potential correlation. Electroencephalogram (EEG) and electrocardiogram (ECG) were recorded at the beginning of an 8-week standard MBSR training course and after the course. EEG spectrum analysis was carried out, wavelet entropies (WE) of EEG (together with reconstructed cortical sources) and heart rate were calculated, and their correlation was investigated. We found enhancement of EEG power of alpha and beta waves and lowering of delta waves power during MBSR training state as compared to normal resting state. Wavelet entropy analysis indicated that MBSR mindfulness meditation could reduce the chaotic activities of both EEG and heart rate as a change of state. However, longitudinal change of trait may need more long-term training. For the first time, our data demonstrated that the chaotic activities of the brain and the heart became more coordinated during MBSR training, suggesting that mindfulness training may increase the entrainment between mind and body. The 3D brain regions involved in the change in mental states were identified.
