Many people have a paradoxical reaction to Cu Lét – both humorous and annoyed at the same time. But no one can find itself right. Livescience.com information portal speakWhy.
In fact, the reality is that the brain is aware of the approach of Cu Lét and deliberately blurred it. The human mind often not only reacts, but also trying to predict what will happen in the future.
Each time you perform a specific action, the brain's main mobility, take responsibility for the neurological signal, send a copy of the command to the different parts of the brain. Therefore, the body is preparing for sensory information, about to appear due to action.
For example, you want to choose a pen. The brain sends the corresponding signal to the hand and finger so that it is to take the pen and lift it. But not only the muscle creates movement to receive a similar group. The brain also sends a signal to the Somatosensory cortex processing information from the sensory organs and visional image shells.
For this reason, people constantly feel their own contact is not as much as others. It is not only about awareness or anecdote evidence; Neurology confirms that the brain creates a less noticeable reaction. And due to the fact that this reaction is predictable, the brain will automatically squeeze it. Review for yourself: Each time, close the car door, you expect to hear a loud knock. But if this sound suddenly changed somehow, the brain realized a mistake in it-that person would immediately remove the seat belt and check if the door was chopped.
Tickling also works in the same way. People are sensitive to external stimuli, regardless of the senses, because these stimuli can affect a person's survival. Our steps create sound, but we hardly hear them, because the brain will talk to the familiar noise. But someone who follows you is likely to be a threat, so we hear the steps of others.
A similar phenomenon is not unique to everyone. For example, the mouse almost does not react to the sound of their own steps. For Cu Lét, an unexpected factor is necessary: the brain should not be ready for the sudden appearance of stimulation. Although there are exceptions – for example, some people with schizophrenia cannot distinguish their actions from strangers, allowing them to be self.
