The extent by which consciousness can take control over the body is remarkable. Biofeedback research, for example, has shown that individuals can learn to control brainwave activity, affect cardiovascular and respiratory functioning, reduce skin temperature, and voluntarily modify many other autonomic processes of the body.
John Basmajian, M.D., Professor Emeritus, Department of Medicine, McMaster University, Canada, who is a pioneer in biofeedback research, demonstrated that people could learn to consciously control individual neurons and muscle cells. Single cell control through consciousness offers the possibility that one can affect any part of one's body, knowing how this works.
