PHYSICS OF BODY ENERGY|
To start at the beginning, the human body (indeed, every living thing presently known) functions on an electro-chemical energy system. This means that, in addition to the chemical vascular/muscular system, you also have an electrically operated nervous system.
This electrical system is controlled by chemicals called neurotransmitters. You already know that electroencephalograms (E.E.G.) are used to determine if a brain is functioning properly. You also know that these electrical measurements of the brains activity are taken remotely, from or near the skin, not directly from the brain itself. In other words, the doctors are reading the electromagnetic field the brain puts out using man-made electrical and electronic instruments even though these tools are crude and relatively ineffective compared to the human protoplasmic and electro-chemical body.
This electro-magnetic field is exactly similar to the electromagnetic field around a high voltage power line. No, its not 40,000 volts, but it is real and is measured through the electromagnetic aura your body emits.
Even though your electrical output is much lower than the local nuke, the electromagnetic aura is unusually large for such small electrical pulses. This is caused by resistance in the transmission lines. The more resistance in the line, the more intense the electrical aura. And, the slower the signal travels.
Superconductors will transmit electricity at the speed of light (almost) with virtually none of the energy drain that line resistance translates to the electric aura. The more conductive the electrical line, the less power loss, the faster electricity is transmitted, and the smaller the electromagnetic field aura.
The human body, however does not transmit electrical signals at anywhere close to the speed of light (about 186,000 miles per second). The largest and thickest nerve fibers conduct electricity at up to 500 feet/second while the thinnest conduct electricity at only about three feet/second.
The high resistance and special design of this bio-electro-chemical system creates a large electromagnetic field in relation to the small electrical charges used. This electromagnetic aura exists all over the body wherever nerve fibers exist.
This bio-electrical system is not exactly like a power transmission line but more like a telegraph line. The body sends short impulses through these nerve fibers. These tiny pulses of electricity, about one thousandth of a second long, occur continuously. Even at rest, your brain sends electrical pulses at least once every second to the entire body and will send (and receive) up to 60 pulses per second during activity.
Throughout your nervous system are junctions, called "Nodes of Ranvier", named after the scientist who discovered them. For the sake of brevity and future lesson use, lets call these Nodes of Ranvier "Tsubos".
Each of these Tsubos creates an even more intense aura similar to the increased electric aura around junctions on power lines. You remember these, you can hear them crackle on a humid day. In fact, some high power electrical transmission lines put out such an intense aura that you can see it on a humid night, especially in the vicinity of a junction.
In an exactly similar way you can see this aura around a person when conditions are just right. You can also measure this aura just like engineers measure the electromagnetic field of a transmission line. Electrical lines bringing power to an appliance in your home vary greatly in frequency and strength. At many junctions, the electricity is altered and "stepped" up or down, changed to 240 volts, 120 volts, or other voltages for commercial usage.
The body also sends out electrical signals of varying frequency and strength. Because the body is a biological system, the electrical signals will vary with the activity and health of the body/mind.
This bio-electrical system has some advantages over the metal electrical systems (and some disadvantages). A big advantage is that the biological system can repair itself. Another advantage is that it doesn't have to be removed to be repaired. Of course, it is slow and inefficient, putting out a lot of waste energy in the form of an electromagnetic aura, but, there's always some good with the bad.
Electricity is transmitted by electrons. ALWAYS! No matter what the system, electricity is transmitted by electrons. Electrons come in two flavors, left spin and right spin. This is from quantum physics but please don't take the course at your local university without a lot of preparation. The electricity you get at home is a mix of left and right spin electrons in a homogeneous mass.
The biological system is able to differentiate between the slightly different electrical aura of left and right spin electrons and preferentially uses them for specific signals. This slightly alters the character of the electromagnetic field when the current is mostly left spin as opposed to mostly right spin.
The brain handles most of the decision making for the body but not all. Somewhat akin to dinosaurs, we have a kind of brain in our back, the spinal column. Since our nervous system is so slow, we have adopted a method of handling emergencies where speed of response is essential. Many reflex actions are handled by groups of neurons in our spinal column, including walking. These neurons are located in giant Tsubos at locations in the nerves of the spine. That way, we can be moving even before we "think" about the danger we're moving from.
The brain uses special chemicals to produce electricity. We do the same thing to power our batteries for autos, radios, toys, etc. The body uses these chemicals extensively in the brain, at each of the remote-control locations of the spine, and at each Tsubo throughout the body.
These chemical substances are called neurotransmitters. There are many different kinds of neurotransmitters. Some cause the electrical signals to fire, some inhibit electrical signals, others speed up, slow down, change the frequency, store energy, etc. The abundance and use of a specific neurotransmitter depends on need, health, mood, food, and much more.
The neurotransmitters and the chemical building blocks for them are stored principally in the spinal column where appropriate transmitters are sent to the brain or body as need arises. This can be done very quickly along the sheath surrounding the nerves and can be far faster in response to an emergency than the rather slow blood-carried adrenaline. Of course, adrenaline lasts longer so the two systems work well together. By the time you've taken the first 10 or 20 steps on "nervous energy", the brain has had time to "think" and tell the pancreas to dump adrenaline....Neat, Huh!
Since flight from fright is the principal savior of the individual, a very large supply of transmitters are carried at the base of the spinal column. Other storage areas include each Tsubo which receives, sends, and manufactures neurotransmitters.
All of this is just science. Plain physics, chemistry, quantum mechanics, and biology, with a little electrical engineering thrown in. Next, we take up the metaphysics of the body.
