HEART-FOCUSED ATTENTION AND HEART-BRAIN SYNCHRONIZATION: ENERGETIC AND PHYSIOLOGICAL MECHANISMS

Author(s): Schwartz, G., Russek, L.

Abstract: Context: Many relaxation, meditation, and imagery techniques that implicitly or explicitly involve focused attention on the body, including qigong, massage, and noncontact therapeutic touch, purportedly employ energetic and physiological mechanisms.Objective: To show that, from a perspective of dynamical energy systems, relaxed self-attention enhances connectivity between the brain and body. This enhanced connectivity may be achieved by at least 2 mechanisms: (1) physiological mechanisms employing peripheral negative feedback loops, and (2) bioelectromagnetic mechanisms involving direct energetic resonance between the peripheral organ and the brain.Design: 19 channels of electroencephalogram, 1 electrocardiogram, and 2 channels of electro-oculogram were recorded from 22 subjects who ' focused their attention on their heartbeats or eye movements, with and without kinesthetic (touch) biofeedback to increase somatic awareness.Results: Analyses of the electroencephalogram synchronized with the electrocardiogram revealed significant effects for heart-focused attention, primarily with touch biofeedback, following the contraction of the ventricles (possibly reflecting incrased baroreceptor and somatosensory feedback); and significant effects for heart-focused attention, with and without touch biofeedback, prededing the contraction of the ventricles (possibly reflecting direct electromagnetic interactions between the heart and the brain).Conclusions: These findings suggest that energetic and physiological mechanisms may be involved in techniques in which the goal is to promote mind-body integration and health.
