With the environmental electrical pollution of small currents but persistent and difficult to isolate, we can be subjected to a constant alarming stimulation that disturbs our sleep, our mood. As a consequence, unwanted behaviors and different ills: endocrinological disorders, high blood pressure, unexplained emotional disorders, etc.
Many times we are surprised that when we touch a metallic object that acts as mass, we discharge electricity. Other times the discharge is done on a person when we touch or kiss them. We see how a spark jumps from our body to the other.
What happened? ... our skin acts as a charge capacitor, accumulating static charges in the same and when it comes into contact with a mass, the discharge is produced that can even form an electric arc that we see as a spark.
These phenomena are much appreciated in winter when when we wear wool or nylon clothes, when we move and rub them, their charge is produced and they are transmitted to the skin, as we are with rubber footwear that electrically isolate us from the great land mass. then, when we come into contact with a body relatively more discharged than ours, the latter acts as an electric mass and we transfer this charge to it abruptly.
It has never happened to him that he is bathing; with the shower curtain drawn and you notice that it approaches you with a tendency to stick to your body?
It is a phenomenon of electrical attraction. Since the curtain, especially if it is made of plastic material, accumulates charge on the surface and we attract it with the opposite charges on our skin.
The loads of the curtain tend to be discharged by our naked body in contact with the ground.
These are everyday facts that serve to illustrate that we are immersed in electric fields that act on our skin.
One of my jobs is to perform EEGs on different patients.
The device detects low potentials (in the order of micro volts). Electrodes are technically placed on your scalp. One of the electrodes must be grounded to eliminate eddy current devices.
These environmental parasitic currents are low voltage, they are electrical noise produced by natural and artificial phenomena.
Artificial ones are all kinds of electrical and electronic devices that we use on a daily basis.
How many electric fields surround us? Paying special attention to artificial ones can be producing harmful effects on our nervous system without us noticing. They influence us in an imperceptible but harmful way. They condition our emotional well-being.
Also how many vibratory phenomena due to noise, moving vehicles, pneumatic drills, etc., may be generating electrical currents in our body fluid and capture them by the nervous system of diffuse pain. Activating our alarm systems continuously and inadvertently.
We live immersed in them and as it is exposed by the records. They influence and influence them with repercussions on living beings. They are difficult to fight. Perhaps it is another price that we must pay in the name of technology. How do we stop it? How far will we go? That invisible enemy erodes our being. How to leave the comfort that electrical and electronic devices are providing us?
Summary of the hypothesis:
A) electromagnetic induction: they are produced by moving our bodies in the environment that is impregnated with electromagnetic fields. They are natural (electrical storms, Earth's magnetic field) or artificial (electrical or electronic devices).
B) vibratory movements in body water: produced by vibrations and environmental sounds. Natural (earthquakes, sunamis, volcanic eruptions), artificial (vehicular traffic, speakers, jackhammers, etc.).
They all have an effect on the skin:
A) by electromagnetic induction: when traveling through our skin, they act directly on the polymodal receptors of the naked fibers of the diffuse pain pathway.
B) the vibratory movements produce electrical changes in the water of the skin (especially of the dermis) stimulating the polymodal receptors.
Why these receptors and fibers are the best candidates to be stimulated:
A) by their distribution and location: they are distributed throughout the skin, mucosa, serous, blood vessels. In the skin they are located in the epidermis-dermis, they are the closest to the outside of the body.
B) due to their greater sensitivity to electrical stimuli: they respond to any nature of stimuli, they are not specific like the other receptors.
C) Unmyelinated: they are not wrapped in this electrical insulating substance, which leaves them more exposed to electrical currents.
D) Structure: these receptors have no structure that surrounds them and electrically isolates them, they are bare terminations.
E) Diameter: they are those with the smallest diameter (thickness), being thinner than the rest of the fibers, they are easier to stimulate.
Why they can influence our mood and behavior:
These receptors and fibers belong to the Paleo-Spino-Thalamic system and it is the oldest pathway from the phylogenetic point of view. It ends in the Limbic system, which is the brain of innate and emotional behaviors. In addition, in their journey they make connections with the hypothalamus, which is an endocrinological regulator; of vital functions such as thirst, hunger, control of the sympathetic autonomic nervous system. It has connections to the colliculi that are nuclei of the visual and auditory pathways (visual and auditory hallucinations?). Therefore we may be being inadvertently influenced by these electromagnetic fields in our emotions, vital functions, endocrinology. The connections to the neocortex are not well known. It is the way that intervenes in this way in the subjective and emotional component of pain. And when this pathway is activated, we do not perceive objective pain, only pleasant or unpleasant sensations (due to the endorphinic system). In other words, the emotional component only, being able to generate alarming reactions and that we stress without realizing it. For other applications and explanations go through the text.
The environmental stimuli referred to are:
1) existing environmental electric fields, which can be detected by highly sensitive devices. There are natural and artificial. The natural ones can be electrical storms, those generated by the Earth's magnetic field, etc. The artificial ones, those generated by any existing electrical or electronic device.
2) Electric fields produced in body water by vibratory movements, sounds.
1) Environmental electric fields:
We are surrounded and traversed by electromagnetic waves of different origins; be it radio waves, TV, cell phones, fluorescent, electric motors, etc. Also, natural ones like the Earth's magnetic field, electrical storms.
Different electric fields can be detected in different ways. When we hear a discharge noise in a radio on when we turn on the light, the noise made by a speaker that is close to a cell phone when we receive a message, etc.
They can also be detected with the EEG device, if the head is left without electrodes, the electrical changes in the environment can be recorded.
This I can exemplify with the following records obtained on different days.
Environmental electrical variations on 07-08-08
As can be seen, it is not an isoelectric wave, but rather it varies by environmental electrical activity, being recorded with an EEG channel.
Detection of electric fields with electrodes in the air, changes when making fluttering movements with the hand in front of the electrode head (arrows).
Note that by bringing the hand closer to the terminals of the head or making a fluttering movement with the hand, electrical changes are induced electromagnetically when cutting said fields by making a movement with the hand.
Then by moving in these fields we induce electrical currents that run through our skin.
We are continually immersed in environmental electromagnetic fields that we are "cutting" by moving and inducing currents in ourselves and others.
Figure 5 corresponds to the digitized simultaneous recording of an eeg channel (upper trace) and the lower one to the recording of a pure tone.
It was performed to evaluate electroencephalographic changes when a tone is passed through headphones. The two records were carried out simultaneously. In the figure the layout is amplified. It can be observed how an electromagnetic wave is induced by the speaker of the headset to the electrodes placed on the scalp that corresponds to the tone in its frequency.
This small induced current acts on the region of the scalp skin where the electroencephalographic recording electrodes are placed.
Figure 6: Spectral examination of the upper trace
Figure 6 corresponds to the spectral analysis of the trace of figure 5. It can be seen in the one corresponding to the electroencephalographic trace (upper) the appearance of the frequency of the tone in question in coincidence when the tone is passed through the earphone (lower); corresponding to the frequency of the tone.
Figure 7: person connected with 3 electrodes on forearm for an examination. 2 of them as registration and 3rd to ground. An isoelectric trace is observed that is modified when moving in the room coinciding with the steps. (07-21-08).
2) Electric fields produced in water by vibratory movements or sounds:
If 2 1-channel electrodes of the electroencephalography apparatus are immersed in the water contained in a container, it occurs that while the water is not moving, an isoelectric record is obtained, that is, straight without variations.
But if we move the bottle with water or tap it on its external surface or, we pass sounds, noises or music through a speaker placed near the container with enough power to make the water vibrate, it will be observed that an electric current can be registered in the water that reproduces vibratory movement.
Here are some examples of these records:
Figure 8 corresponds to the following experience: 2 electrodes are used (1 positive and one negative) from a channel of the EEG, they are immersed in clean water contained in a bottle. Theoretically, water is inert and insulating against electrical influences. However, in the first part of the layout, an environmental alternating current device is observed. When diving a 3rd. electrode with ground connection is observed as this artifact is eliminated. And the register is observed flat, without electrical variations. Then a small movement is applied by tapping on the outside of the bottle, without touching the water; electrical changes corresponding to this maneuver are evident. If we take into account that our body is approximately 70% water. How many electrical changes can be produced in our body before vibrations. movements, etc.?
Figure 8: electrical activity of the water on 07-14-08. That is the same water that was used 4 days before. I leave it in the closed bottle in the corner without touching it. When uncovering it, it had bubbles. The electrodes were introduced and it is observed that it is not an isoelectric line. Water has electrical charges. That after a while it is discharged, it is observed more flat to the route as can be seen in figure 9: in that part of the route variations are observed when I put my hand in the water and remove it.
Figure 15: Small rocking motion is printed to the bottle with water. This plot is obtained. When you stop making the effort, the water continues to move by inertia and gradually stops.
Explain the phenomena
This is a representative diagram of a water molecule, composed of 2 hydrogen atoms and 1 oxygen. With a spatial arrangement of them in such a way that the water molecule is an electric dipole. In other words, it has 1 positive pole and 1 negative pole.
A body of water is made up of billions of molecules.
Then, when subjected to a vibration, movements of the different polar molecules occur, generating an electric potential that can be registered. Recording method combined between electroencephalography apparatus, a microphone, both connected to a computer for simultaneous recording:
Using a bottle containing water that can be ordinary or distilled. 2 electrodes are inserted leaving them submerged in the water. These electrodes are connected to a high gain amplifier. The one used by me is a channel from the Berger model TP 120 electroencephalography device.
At the same time the amplifier is connected to the computer in Line IN. Which has a stereo input. Only 1 channel of this input is used.
In addition, a microphone is attached to the bottle that is connected to an amplifier that in turn the output of this amplifier is connected to the computer on the other IN line channel.
Using a sound program, the electrical changes coming from the electrodes immersed in the water in the bottle and those coming from the microphone are recorded separately and simultaneously in two channels, recording the sounds that are produced when tapping the bottle or the sounds that come out of a bottle. speaker near the jar.
In the upper channel those of the electrodes and the lower channel of the microphone.
Registration system scheme:
Furthermore, with this program a spectral analysis of both channels can be carried out.
Here are some examples of records:
Figure 1a: record of taps given to the bottle.
Figure 1b: spectral analysis from above.
Figure 2a: simultaneous recordings where, in the lower channel, the sound of heartbeat is obtained through the microphone that comes out through the speaker near the bottle with water. In the upper channel, the electrical record obtained with the electrodes immersed in the bottle with water is observed.
The correlation between both signals can be observed. The water vibrates with these sounds and a similar electrical signal is obtained which, when heard, reproduces the past sound.
Figure 2b: spectral analysis of the log waves above.
Figure 4 a:
In the figure above, the sound wave of the tuning fork is observed in the lower channel, in the upper channel the electrical register of the water. The tuning fork wave is not evident, but when doing the spectral examination, the band of the tuning fork is observed, this means that the sound vibration induced the electric wave in the water.
Now, if our body mass is composed of 60 to 70% water, it is logical to think that material waves produce electric fields in our body.
An external phenomenon such as a blow or a sound wave, the first thing they come into contact with is our skin. Which is the largest organ in the body. With millions of different sensory sensors (called receptors). Also, an electric current in the external environment, the first thing that finds its way into contact with our body is the skin.
So it is important to start with studying the structure of the skin and its nervous relationships.
Skin Characteristics: figure 5.
It consists mainly of 3 layers.
A- epidermis: it is in contact with the outside, made up of tightly bound epithelial cells. Coated on the outside by keratin.
B- dermis: it is the intermediate layer. Made up of connective tissue, rich in water.
C- hypodermis: innermost layer. Mainly made up of adipose tissue (fat).
It is the largest sensory organ, it covers us completely, it is the most exposed to the outside.
Through it we can perceive different sensations. Fine touch, caresses, pressure, heat, cold, vibrations and pain. In addition, a combination of sensations such as tickling, itching, etc .; there are many sensations that we can have with the skin.
How to perceive these electrical changes?
In human skin, no sensitive system has been found sensitive to the detection of electric currents, such as sharks possess, for example.
But, any nerve fiber can be electrically stimulated and it will respond with nerve impulses. This is how some electrophysiological studies are carried out, such as electro myography when studying the speed of nerve conduction of a nerve.
Before moving on, it is important to make some clarifications about the nervous system.
The nervous tissue has the fundamental ability to react to stimuli, it is the tissue with the highest excitability in the body.
This power is given by neurons, which are cells specialized in getting excited.
Basically, neurons are made up of a body (where the cell nucleus is) and processes called dendrites on the one hand and axon on the other. They come in different shapes, sizes and number of branches.
According to the number of branches, the basic ones are:
The sensory neurons connected to the skin are the pseudounipolar ones.
The property of excitability is given by the electrical changes that occur in the plasmatic membrane of neurons.
The membranes of cells in a state of rest have an electrical voltage by distribution of charges inside and outside the cell. Where the interior is negative with respect to the exterior.
Figure 6 a: scheme of charges on the plasma membrane at rest. Pseudounipolar neuron scheme amplification.
A stimulus produces a local change in the polarity of the nerve membrane, which upon reaching a certain intensity value this phenomenon begins to spread throughout the nerve fiber membrane. Until the entire membrane reverses its electrical polarity completely. As seen in the following figures.
The change in polarity is due to ionic exchange that spreads throughout the nerve fiber.
This propagating potential is called ACTION POTENTIAL, which is the physical representation of the nerve impulse. So, as you can see, the electrical impulse is an electrical change in the membranes of neurons. In this way it is logical that electrical changes in the environment surrounding the fibers produce an effect on them and it is legal to think that nerve impulses are caused by electrical changes both by electromagnetic induction on the surface of the skin, as well as those that occur in body water especially on the skin.
What is the most optimal way to stimulate yourself with these electrical changes in the environment?
Excitability refers to how easily a stimulus can provoke a nerve impulse in these tissues. When it is easier, this means that a lower intensity of the stimulus is needed to produce it, it is said that the excitability is greater.
In a nerve fiber, the smaller the diameter of the fiber, the easier it is to excite it.
In addition, a fiber can be influenced by adjacent electrical changes, these electrical changes near the fiber will influence fibers that are not coated with myelin more. This is a greasy substance that electrically insulates the fibers.
For all the different perceptions (touch, pressure, heat, cold, stretch), except slow pain, the fibers are coated with myelin that electrically insulates them.
Every sensory pathway begins in a stimulus receptor, which is the structure that will translate the stimulus into a local electrical change whose intensity and duration is in direct relation to its intensity and duration, once it reaches a threshold value, the electrical phenomena that propagate through the plasma membrane of the nerve cell described above.
For the pathways of touch, pressure, heat, cold, stretch, their receptors are located in the hypodermis below the dermis, while the slow pain receptors are located in the epidermis and dermis. Those that locate them closer to the external environment of the body.
Analyzing the pain path
If the skin is the largest organ of the body, it has a large distribution surface, enveloping our entire body, under certain biological conditions, the electrical influences of the environment generate currents on the skin that serve as stimuli to generate small nerve impulses that as starting point on the body surface enter our central nervous system producing behavioral modifications.
Although human skin does not have known receptors for electrical stimuli, with electrical impulses applied to it, action potentials on nerves can be obtained and the speed of nerve conduction or somatosensory potentials can be measured. This is because the electrical change produced by the stimulator generates an electrical change in the nerve membrane and the action potential (nerve impulse) is produced.
How many times has it happened that during a stormy day behaviors in animals and even people are altered. When the environment is charging electrically and then the electrical discharges of a storm begin. Electrical discharges occur from top to bottom with charges that accumulate in clouds and discharge to the ground. These electrical stresses must act on our skin and produce changes that lead to changes in behavior.
How does this produce changes in behavior?
Nerve impulses have the action potential as a physical representation. This is an electrical change on the membrane of nerve fibers that travels through them. As explained above.
At the skin level, they are generated by electrical changes in the stimulus receptors located in the skin. The skin has a variety of receptors for stimuli; receptors are structures that respond to an appropriate stimulus. It is said that a type of receptor is prepared to respond to a type of stimulus that activates it with a minimum of energy.
Thus, there are those who respond more easily to a type of stimulus. Example: for the pressure stimulus there are specific receptors to respond easily to said event and not to another type of stimulus; such as heat, for this type of stimulus there are receptors that are easily activated by heat.
Then, according to the nature of the stimulus that activates the receptors, these are classified within the mechano receptors, chemoreceptors, etc.
Stimuli are physical-chemical changes in the environment that, upon reaching a threshold value, trigger the production of action potentials (physical representation of the nerve impulse) in the nerve fibers that propagate centripetally, entering the central nervous system.
In this way the receptors are specific for each type of stimulus. There are those who are sensitive to heat, cold, pressure, gentle contact, pain.
The impulses that reach the area of the parietal cerebral cortex of each hemisphere is where we become aware of the sensation. For example, if they touch us on the right hand we perceive it, we become aware when these impulses generated in the skin reach the left parietal cortex.
The sensations may or may not be pleasant; These sensations are related to pain pathways.
All pain has two components, one objective as a sensation and the other the emotional component that it causes.
The emotional reaction can range from a feeling of discomfort to a mood disorder that can lead to depression. Even go to suicide.
The emotional component is related to pain tolerance.
Pain from the physiological point of view is a protection system against physical damage. If something causes us pain, we usually move away from the source of pain to protect the body structure.
Painful stimuli generate alarm behavior to protect us. With this alarm system activated, the stress mechanisms are set in motion.
In pain perception there are a special type of receptors that are stimulated with different types of stimuli regardless of their nature. They are called polymodal receptors because they respond with any type of stimulus, be it mechanical, chemical, thermal.
They are made up of unmyelinated nerve fibers, they are distributed as free endings in the dermal-epidermal junction. They are the receptors of the skin closest to the outer surface. They belong to the oldest pain pathway from the phylogenetic point of view. Called paleo-spino-thalamic.
So, we can assume that the electrical currents that run through our skin can stimulate these polymodal receptors only and since one of the terminal points is the limbic system that generates alarm system activity they can trigger alarm responses. Unexplained pains
With the environmental electrical pollution of small currents but persistent and difficult to isolate, we can be subjected to a constant alarming stimulation that disrupts our sleep, our mood. As a consequence, unwanted behaviors and different ills: endocrinological disorders, high blood pressure, unexplained emotional disorders, etc.
a) The limbic brain: part of the brain where emotions are registered and generated.
b) pituitary: the mother gland and controller of the others in the body.
c) hypothalamus: brain region where appetite, thirst, blood pressure, heart rate, in short, all neurovegetative functions are regulated.
d) geniculate bodies of the visual and auditory pathways.
These free terminations almost in direct contact with the outside, separated by the thin cellular layer of the epidermis, which is distributed over the entire body surface, are the best candidates to receive stimuli of this nature by which they would act under special conditions trying to introduce the stimuli in the nerve pathway and thus trying to reach the brain.
In addition, the pathways corresponding to diffuse pain on its way up the brain stem, which is immediately below the thalamus, emit fibers that are distributed in a system of neurons that form a network for this reason called the reticular system, they make contact with the diffuse nuclei of the thalamus, also direct fibers to the hypothalamus and pituitary; The latter is a coordinating center of the organism's glandular systems and the neurovegetative system that mediates neurovegetative responses such as cardiac, respiratory, and vasogenic activity, in short, all the systems necessary for life and maintenance of the stable internal environment without the mediation of the will. .
This route would be an alternative that could be responding to many phenomena that can occur repeatedly. Without a clear explanation of why they occur.
It is to perceive by feeling emotions exclusively.
When the activation of this tonsillar nucleus (limbic structure that generates fear reactions) is very intense, irrational behaviors can be generated due to fear. That they are no longer useful for defensive purposes.
In a state of equilibrium, faced with a feeling of fear (lower degree of fear), with the logical brain we will do an analysis and search for a better defensive strategy. When fear behavior is irrational it is because the limbic is freed from the inhibition of the logical brain.
Then this sensory pathway is stimulated by electric fields generated in the environment or by vibrations. Only of sufficient intensity to activate this paleo-spino-thalamic system that ends in the emotional brain and we will only be aware of the sensation of fear without being able to rationally explain why.
If environmental electric fields exist and can be recorded; as well as water vibrations generate recordable electrical changes. As they were demonstrated.
If a high percentage of our body mass (60 to 70%) is made up of water, these electric fields must be produced in our body by vibrations.
If both the electric fields and the vibrations of the environment with the first thing that our body comes into contact with is with our own skin. This is where the answer should be sought in the first instance.
If she is the largest organ of the body, than we contact the outside environment. It has a structure and sensory functionality explained above.
If within these sensory structures are nerve fibers with a greater probability of being stimulated by these electrical currents than the rest of the fibers. Because they are the finest, do not have an electrical insulator, being the closest to the external surface, travel through the dermis rich in water, which is the body water closest to the outside that a vibration can make it vibrate (worth the redundancy).
These fibers belong to an ancient system that has many connections and ends in the limbic brain.
So if this pathway is activated alone, by small electrical currents that could not activate the other specific sensory pathways that start from the skin. We perceive emotional sensations inexplicable to rational logic.
It is totally reasonable to think that it may be the gateway to the explanation of a totally new way of perceiving reality for neurophysiology. With its unsuspected derivations and allows us to rationally understand phenomena that occur many more common than we can suppose. But we systematically dismiss them for lacking logic or ability to be explained.
