Surely you have ever felt that there is an energy field around you and that serves to warn you of possible dangers, and that even protects you, as a force field.It would become as if the awareness of yourself were beyond the flesh.This space has been recognized by science for several decades , and is called "peripersonal space."
Although not all people are aware of this space or field, scientists have used a trick, or an illusion, that can make us aware of its existence.
Can you feel a force field surrounding you?
Have you ever diverted your face seconds before receiving an unexpected blow or avoided collision with a branch that you apparently had not seen, as if you would be protected by a force field.Not so, there is no fu field erza protecting you, but if a field of consciousness , or as they prefer to call it psychiatrists and neurologists, a “peripersonal space”.
The peripersonal space is the one that surrounds our body and from which the brain is aware that any object or movement that is performed in this environment is supposed to be detected by the body and generate a defensive or protective response, such as the sudden closing of the eyelids when an object violently approaches the face, or movements arms defense to prevent an attack that has not been seen.
Research on primates has shown that there are areas of the brain for the control of peripersonal space, which can they can be activated or "deceived" through electrical impulses.Another study recently published in the journal Cognition describes how an illusion or trick can show us the existence of this force field.
The rubber hand illusion is a sensory trick that involves placing an artificial hand next to the volunteer's real hand, which is out of sight; Initially, two brushes are passed through the surfaces of both hands, but then the real hand is stopped, and yet it is very likely that the volunteer will continue to “feel” the brush that continues to pass over the rubber hand.
The illusion shows that the sensation occurs in the head and not in the hand , and that our nervous system can be deceived.
A team of researchers from the Karolinska Institute in Stockholm (Sweden), coordinated by Arvid Guterstam , tried a variant of this trick on a hundred volunteers.They began repeating the classic illusion, but then began to pass the brush a little above the rubber hand, without touching it , making a high number of participants feel the presence of the force field, that is, of the peripersonal space, that apparently extends up to about thirty centimeters around the body .
Naturally, This experiment also shows that the sensation of this force field is in our mind, but it also serves to protect us from possible impacts, real or imaginary.Nor should you confuse this space with that of social interaction, which varies between different cultures.and that sometimes produces misunderstandings, as sometimes happens between Latinos and Anglo-Saxons.
We recommend these incredible things that the brain can do without you knowing it, and see if you have scopaesthesia, if you feel the looks.
