Proprioception from the Latin word for self….Is referred to as the sixth sense by some, and has to do with body position, and movement of muscles, or in space when the body moves. There is posture of the body and how it’s muscles and limbs move. It involves feedback from the brain, and from the body. However, this information is not always conscious, it can be unconscious.

What exactly is proprioception? It is the sense of how our body is positioned and moving in space and in our environment. This awareness is produced by part of the somatic sensory system and involves structures, called “Proprioceptors” in muscles, in tendons, joints, and ligaments that monitor changes in their length, in their tension levels, and pressure linked to any changes in position.

Proprioceptors send impulses to the brain. Upon processing this information, a decision can be made to change position or to stop moving. The brain sends back to the muscles based on the input from the proprioceptors, which then complete the feedback cycle.

Bicep muscle moves through an elongation or contraction and your brain is aware of movements, consciously or unconsciously. These signals go to the sensory cortex and process input from the muscle’s biceps.

The Sensory neurons carry sensory information to the brain. Muscle spindle fibres detect change to the length of the muscle. Positional sensors is information from proprioceptors, such as muscle spindle  fibres, that are sent to the brain for processing. There are position sensors in the joints, sensors within the the tendons and muscle stretch detectors all working together to create an image of the body position. It tells us if something is wrong.

Types of proprioception  information is either made conscious or processed unconsciously.

For example: Just keeping and adjusting balance is generally an unconscious process. Conscious awareness is being aware of something through sense intake and output. Proprioception usually involves some kind of Cortical processing resulting in decision making. This normally is sent in commands to the muscles to perform a movement. The sheer amount of proprioceptive inputs means that much is processed unconsciously.

Proprioception Pathways;

Conscious proprioception uses the dorsal column medial leminiscus pathway which passes through the thalamus and ends up in the parietal lobe of the cortex. Unconscious proprioception involves spinocerebellular tract and ends up in the cerebellum, the part of the brain in the back of the skull which I call the amphibian part of the brain. It is involved with movement. The spinothalamictract, the spinocerebellular tract, and the cerebellum the amphibian brain, and oldest part of the brain in evolution, and then the pathways up into the cortex where the parietal lobe is the last part of the evolved brain of the homo sapien are involved. And these pathways are involved in control of movement or sixth senses.

Phantom Limbs;

When someone has a part of the body amputated or removed, be it limb or an extremity, such as an appendix , they sometime continue to have sensations, often including pain, in that area. Research has linked this to changes in the sensory cortex. Specifically the somatic sensory cortex’ which undergoes a remapping process in which the area near the “dead” area “take over,” so that the stimuli in these areas are felt as sensations in the area that has been lost. This reorganization of the cortex has been confirmed through imaging studies.

Before computation;

Sensory inputs from the arm and hand are connected to the appropriate regions of the sensory cortex, the evolved part of the brain through those above pathways, and other parts of the body are connected too, to specific neighboring areas in the cortical regions, or sensory somatic regions. So there is always reshaping the sensory map which produces real sensations.

To experiment: Take a scribbler, take two pages of the lined paper, between your your thumb and first finger, and feel them, now take 10 pages between your first finger and thumb and those sensory proprioceptors will tell your cortex the differences in sensations. You can feel the differences of even the pages in a book.

Close your eyes in this experiment: get your husband to sit still, and with your eyes closed, feel his face with no sight and the different shapes, places in space, the skin tissues, the layers of thickness, the feelings of just a face and it produces all new mapping and sensations and sensory mapping inside your cortex.

Now Moving on: “Phantom Limb Pain Treatment”

Research has shown that the development of phantom limb pain is linked to the plasticity of the sensory cortex. Trying to reverse the changes in the cortex, the pain sensations in the cortex can actually be reduced for the patient. For instance, if you use an electric prosthetic limb that is moved by signals from the patients muscles, it helps with mapping new pathways. Brain scans revealed this was linked with reversion of the Cortex to it’s original state maybe by replacing some of the original inputs of movements without pain.

Mirror Treatment:

When a patient’s remaining arm is shown in the mirror image and moved,  it looks as though the missing arm is moving. Somehow this illusion can remove phantom limb pain.

How Sensory Pathways, or Sixth Sense Pathways can tell you something is wrong;

Just like in pain, there is primarily a warning system or a warning signal. It tells you something is wrong and forecasts you to take action. Pain occurs, or uncomfortable feelings or sensations do occur according to stimulation of specialized nerve fibers that are extended throughout our bodies. Pain pathways, or uncomfortable pathways when something is wrong permeate the fibers in every part of our body. When stimulated by past personal pain or knowledge, or an injury, these electrical signals from the site of the stimuli come up the spinal chord in the corticospinal pathologies up to the cerebellular  tract, and up through the thalamus into the Cortex areas of sensory somatic areas. The signals that pass over the spinal chord continue to the brain areas in the cortex and can activate the opposite side of the brain. As these signals pass through the medula in the brain stem these signals trigger off automatic body responses. The signals arrive at the thalamus and are distributed to the various regions of the brain and are processed. Chemical are then released if in pain, bradytinin and ATP which triggers the nerve impulses that experience the sensory data. Some chemicals can be released that are histamines, which are released by white blood cells, also  can they cause injury sites to become inflamed making capillaries swell up. Sometimes these signals in the brain can be released before consciously felt and distributed to the cerebral cortex which interprets the signals of “something is wrong.” “SOMETHING IS WRONG”

In covid 19 evidence there were particles found in skin endothelial cells, and it had entered through skin rashes and showed symptoms in patients when the covid 19 spike protein entered the Ace 2 protein destabilizing the proteins of the skin cells, and  hence killing cells, but had no other signs of disease. There are 5 groups of covid 19 manifestations….(1) chilblain like  lesions  (2) maculopapular eruptions (3) Urticaria eruptions (4) Vesicular eruptions (5) livedo or Necrosis.

To add onto all the organs, like lungs, kidneys, liver, heart, intestinal areas, there was blood clotting, thrombosis, blood disease, myocarditis infarction,  pericarditis, lung lining where the covid 19 spike protein was found to be killing cells. Spike proteins were found on the larynx, tonsils, tongue, in the fesces, in mucus, in white and grey matter in the spinal tracts, in the spinothalamic tract, in the spinocerebellular tract, in white and grey matter, and in the Central Nervous System. The immune system can have robust epigenetic changes in stem and progenitor cells as well as in their progeny, mature innate immune system cells, like the mitochondria ATP levels. This can reshape the immune threats stated by research. EG5 and B.A.2.86 had spreading abilities and had 30 differences to past variations,  showing that variations could change to deadlier types.  Aphasia too in the Frontal Temporal Area of the brain and white and grey matter, and in area four, are related to all muscle movement, in joints, space and sensory somata, and the neurons were being killed. The spike proteins destabilized and killed cells and caused crippling muscle problems, and brain sensory somata which in turn problems and giving the brain disorders.

Proprioceptors are indeed necessary for sensory data to inform us of when we are in trouble with our environment and surroundings, and give us warning, that “Something is Wrong.”
