The human brain is the subject of study by many scientists around the world. About 10 such techniques will be discussed in this material.
10. Pain Relief
It often happens that we inadvertently inflict injury on ourselves, resulting in characteristic pain. However, if a person tries to look at the damage on his body through inverted binoculars, then the intensity of such negative sensations will surprisingly begin to decline.
This conclusion was reached by researchers from Oxford. In their opinion, if using a trick with binoculars, a person visually reduces the area of the wound surface, then the pain that he experiences will begin to pass. This experience indicates that the perception of certain sensations to a large extent depends on visual images.
9. Deception
In such an experiment, at least three should take part. One of them will perform the function of a test subject, while the others will monitor the progress of the process and assist.
First, you need to attach a long tube to ordinary headphones. The subject sits down on a chair, and the other two on the right and left hand from him should stand up and put the tubes with headphones to his ears. Assistants, one by one, will start talking into the phone. The test subject in this way can correctly indicate the side from which the sound originates. However, if they switch places, the subject will begin to go astray and incorrectly indicate the sound source.
This phenomenon can be described as the ability of the brain to choose the right direction, guided by the sounds conveyed.
8. The Hanzfeld procedure
This experience was first implemented in the 30s of the last century. Its essence lies in auditory deception of the brain. For its implementation, you need an ordinary radio and a ball for table tennis.
To get started, tune the receiver so that only one interference is heard. After that, you need to lie down on the bed, close your eyes and attach a half of the ball to each eyelid. Very soon, you will begin to see hallucinations (both visual and auditory images).
What is the reason for this phenomenon? Not everyone knows, but our mind broadcasts what we feel, and when there are few real sensations, the mind begins to generate them on its own.
7. The illusion of a spinning silhouette
The video allegedly shows the rotation of a female silhouette in a certain direction. Most people watching this video clearly feel that the rotation is clockwise. In reality, this figure does not rotate at all, but moves rhythmically back and forth. However, our brain perceives this picture in three-dimensional form, and because of this it is difficult for him to “discern” the true direction of movement of the silhouette.
6. The Pinocchio Illusion
The result of this experiment clearly demonstrates an example of how a person can deceive his consciousness with the help of tactile signals. To perform this experiment, you need to take two chairs and a blindfold. Subject puts on a bandage and sits on a chair. Opposite him, another subject sits. A man with his eyes closed simultaneously touches the nose of another subject, and his own. Gradually, he begins to stroke both noses. If such an action is performed for at least 1 minute, then the person in the bandage can clearly feel that his nose is getting longer.
5. The perception of light
Try keeping your gaze on the “+” sign, which is located in the central part of the image. Continue to continuously watch him for half a minute, and then look away at the wall. There you will clearly see a spot for some time.
4. Deception of thinking
Raise your right foot slightly and begin to make small circular swings clockwise. At the same time, with your right hand, try to draw an imaginary number 6 in the air. Now you will clearly feel that the leg is moving in the opposite direction against your will, and you can not stop it. To a certain extent, such a phenomenon cannot be fully considered a hoax of consciousness - it is rather a physiological feature of the brain.
3. Purkinje effect
To conduct this experiment, it is necessary to close your eyes, stand to turn to the sun and try to drive your hand in different directions as quickly as possible. After some time, you will begin to see a variety of images, and some of them can be very realistic.
2. The illusion of a rubber hand
In order to independently reproduce such an experience, it is necessary to inflate a rubber glove, and also take one towel and 2 brushes. The inflated glove must be put on the table located in front, while your own hand must be hidden under a towel. After that, tell the assistant to start stroking both hands simultaneously with the tassels. After a while, it will seem to you that the dummy hand is yours. If at this moment the assistant hits the glove, then you can clearly feel pain, because your consciousness will consider the glove to be one of its own limbs.
1. The sound that is heard by those who are under 20
Scientists have found that sound in the form of a sinusoid, having a frequency of 18,000 Hertz, can be recognized only by people under 20 years of age. Some very inventive teenagers have adapted this property of the nervous system to their needs - they use this sound as a phone signal. Thus, parents or teachers at school do not hear when his phone rings.
