without sense organs, perception of that organ: Ghost Limb Syndrome

We don't know if it happened to you before, but it's one of the interesting syndromes.
so let's say you lost your left arm from the elbow down in an accident, when you touch the elbow above and ask "what do you feel", the patient in the link I gave below says, "I feel you touch your fingers of my left hand." The mental angels of these patients are in place, and they are also aware that the organ is not there anymore, but what they cannot control is the "non-phantom" sensation they perceive to have that organ.

50 to 80 percent of patients with a specific limb have phantom limb syndrome. they usually say they feel "pain" in this non-organ; more precisely, in some of these patients, whether they have lost their arm, while they feel the sense of this arm, some of them perceive "severe pain". vilayanur p. According to the explanations of Ramachandran, a syndrome that can occur even in internal organs; For example, a woman with uterine surgery can suffer from "phantom menstrual cramps" before her period.

With its physiological explanation; The a-delta / c nerves from the spinal cord to the midbrain go to thalamus, where pain and / or pain is first detected, and to somatosensory cortex, which is responsible for specific and local pain perception. "According to the modern theory of non arm / leg pain *, there is of course no" sense "from these limbs that have been lost, but thalamus still sends the nerve impulse to the somatosensory cortex as it exists and completely randomly. somatosensory cortex de thalamus' This is one of the situations where we can see the difference in senses and perceptions clearly, as I perceive this nerve stimulation, which comes from the brain and which is actually completely brain-brain nerve conduction, perceives it as coming from the broken limb.

Now, the point where the shit of the incident really came out was water, the ramachandran mouth: Let's say the patient had an accident and most of the nerves in his arm were crushed. The arm was paralyzed as a result of the cutting or crushing of the nerves going to this arm, and the patient would suffer for months. According to his medical condition, the doctor decided to cut his arm, and let's say the arm of the patient was cut. but the patient still feels the same pain in his arm that is still not there? I think that the human is going crazy, which is becoming a very serious clinical problem, and there are also suicide suckers from these patients. So what does it feel to just feel the arm that is not there or feel pain in the arm that is not?

ramachandran explains this situation, if it is not only the limb that is not the limb, but this is often due to trauma prior to the accident. On the other hand, when the arm paralyzes after the accident, the frontal lobe of the brain sends the command to "arm" the arm, but it does not receive visual feedback because it sees that the arm cannot move. During the months when the arm is paralyzed, the brain continues to send orders to the arm (nerve stimulation about movement) and the arm continues to move because it is paralyzed. This communication between the brain and the arm in the months before the paralyzed arm is cut creates a "learned paralysis" * for the brain.

(see classic use / @ procastinator)

This learned paralysis continues to be frozen by the brain after the arm is cut, and "pain" is detected in the cut arm. modern time neuroscience god canim ramachandran needs to teach / forget the brain by reconditioning this learned paralysis. I am really sick, there is no one I admire more in the modern world of psychology.

because let's look at the solution he found: how did this learning happen? the brain sent the arm to the arm several times and for a long time, but it did not get a response. the arm was cut, but the brain continues to send signals, and because it is "condensed," it is suffering from pain that is essentially used for a limb. If we can deceive the brain in the form of visual feedback, that is, it continues to send the order with nerve stimulation, if the hand is moving, maybe the pain will be over?

At this point, it comes with the "mirror box" exploration. this is a box with a mirror on the side where the cutout arm is. You push the solid hand up to the arm and start playing left and right, the right else you insert from the nature of the reflection looks like the left hand. Visual feedback tells the brain, "The paralysis in the left hand is over, it is following the orders and it is moving now." because when they move their hand to the mirror, they say look at the reflection in the mirror and the patient says, "Oh my God, the paralysis in my hand has disappeared and it is moving now."

More interestingly, after the first attempt of ramachandran, when he says "shut eyes" to the patient who says "my phantom is moving", that is, when the visual feedback is cut, he is unable to move his non-patient hand again. But when he looked at his reflection in the mirror by opening his eyes and moving the solid hand again, the phantom said that the hand started to move again. If the patient was old, it was over. Anyway, after all, the patient takes this mirror box and brings it home and does this exercise every day for a week, and after a week the pain that he has been suffering for ten years and the pain relievers have not disappeared will not disappear again.

Let me prolong the word, let's come to the interpretation of the work:

- We stop the pain that the painkiller cannot stop by manipulating the "learned perception" of the brain. This means that for years, such as yoga, meditation and hypnosis, especially the ways in which the treatment is not useful and to relieve the pain perception of cancer patients with excessive pain, to get rid of various addictions, or to relieve stress in the most basic way, our brains have learned both these methods. "We can change the perception of pain / stress by disrupting practices and introducing new practices.

- adapt this to any social thing, come to $ k or any unfinished business, sometimes a loved one's going turns into phontom limb and especially if you are paralyzed before this departure / break, it feels like there is still no human being, or you may be continuing to paralyze the old trauma.

Therefore, the equivalent of Ramachandran's mirror box in social life is to solve unfinished business. and for this reason, we return to the scene of the event most of the time to solve the unfinished works. or if that person is someone we have lost / or has been, it is possible for us to put the therapist in his place and get rid of the angst inside us with methods such as "what would you say if he were here".

In fact, when we are aware of these mechanisms, we may not need the therapist as well, if you want to deal with such a stupidity that you want to solve it, if you really want to get rid of it, you can put a friend you trust in your wife and if you do not have a friend (and even ramacharan) I think that if you feel what you think about this endless issue, if you feel like that person is in front of you, it is a method that has been applied in clinical psychology for years.

If the traumas are learned even in the perception of physical pain, it may be that in social situations the pain immediately after the loss is seriously signaling that thalamus sends randomly, and that the brain is constantly sending a signal because he wants to see the "loved" that the brain cannot see. Look, at the moment I got the chick sticks the chick in this case mirror box, is it good. hey gone.

the law, I want to end this entry as exist ramachandran.
