The effect of magnetism on the nervous system
The nervous system, like other parts and attributes of the human body is subject to the effects of magnetism and magnetic products. That is the view of such researchers as G. W. de la Warr, Dr. Albert Roy Davis and Dr. A. K. Bhattacharya of India.
The Central Nervous System is comprised of nerve cells known as neurons which generate energy that can be transmitted through their outer walls along something called an axon. If one thinks of the neurons as miniature batteries, then the axons are like the electrical wiring that they use to carry the current. The wiring analogy is very appropriate because axons are covered by an outer layer called myelin, which acts like the insulation layer on an electrical wire. The myelin also increases the speed at which the impulses are conveyed along the axon.
When a neurons is activated, it transmits a signal to the central nervous system. The connections that link the neurons are called synapses and there are something like ten trillion synapses in the brain and spinal cord. This makes the layout of the central nervous system far more complicated than the national grid that brings electricity into people’s homes in even the largest developed countries.
Neurons can be activated by the sense that we call touch. But this sense is actually several things that tend to be lumped together. Touch, temperature, body position, pain and the state of muscles all convey signals to the nervous system that the person then “feels”. It is the sheer complexity of the nervous system that makes it possible for it to convey such precise information. Most of us can distinguish the touch of a sharp object from a blunt one because of this precision. And we can tell where are limbs are with our eyes shut for the same reason.
These signals – which ultimately reach the brain – are based on electrochemical impulses. Specifically, nerve cells carry a negative charge on the inside and a positive charge on the outside. When a nerve is stimulated, the positive charge is increased allowing positive ions to enter the cell. This charge is in turn passed on to the next cell, until ultimately it reaches the brain.
Because of the relationship between electricity and magnetism it is possible to use the negative pole of a magnet to reduce the positive charge at the surface of a nerve ending and thus decrease its capacity to transmit pain. This turns the magnet into a kind of local anaesthetic, although it does not remove pain in its entirety.
Thus it can be seen that magnetic products have a theoretical as well as a practical basis for palliative therapy. Magnetic therapy pain relief is therefore not a purely psychosomatic effect but rather the result of the underlying physics and physiology of the human body.
