Dr. Fleet taught the following: "There are only six kinds of disturbances that can affect the human body. These are GLANDULAR, ELIMINATIVE, NERVOUS, DIGESTIVE, MUSCULAR, and CIRCULATORY. All diseased conditions, aches and pains, and other discomforts experienced by the body can be attributed to one or more of the above disturbances to the body’s six systems or zones."
According to Dr. Fleet, the human brain is comprised of many centers. These centers form in the embryonic stage of life and develop from the dorso-medial ectoderm of the embryo. There is a center that controls the glands of the body, a center that is associated with the organs of elimination, and a center that regulates the central nervous system and is differentiated as an ectodermal neural plate in the dorso-medial region of the ectoderm. The digestive organs are regulated by a brain center. In the motor cortex of the brain we find a center that controls all of the muscles of the body and in the caudate nuclei, we find the center that regulates the flow of fluids (circulation) through the body.
Because the body may be properly classified as an ELECTRICAL MACHINE, these six brain centers represent the POSITIVELY-CHARGED POLE of the body, and specific related points in the spinal cord represent the NEGATIVE POLE of the body. When there is a disturbance in any of the bodily areas, one or more of these centers are "shorted out."
There has been a disruption of normal function of the entire center due to the effect of emotional, physical, or chemical stress.
The Zone doctor examines the patient to determine which of the brain centers are not in harmony with the systems they control. This is done by the Zone doctor palpating (feeling) specific points on the patient’s head. These points are related to the six brain centers by nerve connections. When a brain center is not sending the proper signals to its system, all bodily material associated with that system degenerates. In order to correct this, Zone doctors stimulate specific segments of the spinal cord. The balanced brain centers are then able to send out the proper signals to the body’s systems, and the body is better able to heal itself.
