Déjà vu is a wonderful sensation, many people think it's the key through the door of the memory warehouse of a past life, while others think it's a cause of epilepsy. Pen % fun % Pavilion www.biquge.info

It is also believed that it belongs to multidimensional space and parallel universes. It's just that there are different opinions about what it is.

Su Yu couldn't figure it out for a while, and his mind couldn't help but think of all kinds of analyses and speculations about the sense of déjà vu, trying to get some inspiration from them and find out the source of why he had such a strange feeling for Zhao Xiaoai.

According to the speculation of scientists in the old era, this sensation is the result of the interaction between the perceptual and memory systems in the human brain.

If one wants to understand why there is a sense of "déjà vu," one should start with the categorization aspects of perception and memory.

Categorizing what you come into contact with is an essential feature of perception and a fundamental feature of memory.

A person's perception includes the perception of time, the perception of space, the perception of objects in it, and so on.

Because the objects of these three kinds of perception are different, when human beings arrive at a place, the orientation and spatial relationship, the surrounding objects, and people may appear at the same time.

In other words, these things poured into the human cerebral cortex at the same time.

However, human perception of them is carried out by three different circuits in the brain. Similarly, human memory has become three categories, rather than a unified one.

That is to say, when we see something, we see it as a whole, but in our brains, we cut it into parts and store them separately.

When we need to remember, put it back together.

Therefore, human memory is also divided into many types, including episodic memory and semantic memory.

Episodic memory is prone to a sense of disorganized perception, giving people a sense of déjà vu, as if they had been to a place in a previous life. And in this life, when I came to this place again, I thought that the memories of my previous life had been partially revived.

Semantic memory is the memorization of knowledge and feelings. What a person learns in school, as well as organized knowledge of rules, formulas, and algorithms that operate these symbols, concepts, and relationships, etc., can be attributed to semantic memory.

The organization of semantic memory is abstract and generalized, and the information it contains is not limited by the specific time and space of the information received, but is based on meaning. As a result, semantic memory tends to be less disturbed than episodic memory, and it extracts information more quickly and does not even require searching.

So semantic memory rarely has a sense of confusion. Even if a person can't remember a concept, he can't tell several formulas. But when he saw these formulas and concepts, he also knew when and where he had learned them. He knew that he had actually been exposed to these concepts and formulas, so he had little sense of déjà vu.

But episodic memory is different. Episodic memory is the memory of an event or situation that an individual experienced and that occurred at a certain time and place.

It is a memory of a plot, an experience, a passage of events, and is often an unconscious memory.

This kind of memory time and space is the coordinates, involving specific events in the individual's life, and the information it receives and maintains is always related to a specific time and place, and is based on the individual's experience.

As a result, episodic memory is more susceptible to interference than semantic memory, and it is also slower to extract information, often requiring an effort to search.

Each of these types of memory can be divided into many subcategories. Precisely because both perception and memory are "classified", the numerous features of some scenes that a person has experienced will be stored in different memory systems that the person himself is not aware of.

When the person walks into a new scene, certain parts of the scene may stab some of his memories, mobilize different memory systems in the brain and match them. Once a feature in the scene matches a past experience, a sense of "déjà vu" is created.

Everyone will have their own life experience, because there are many things accumulated unconsciously in the past, so it is normal to occasionally have a subjective experience of "déjà vu".

But Su Yu didn't think that the feeling of déjà vu between himself and Zhao Xiaoai came from some kind of fragmentary memory in the past.

He just found a familiar smell in Zhao Xiaoai, but he couldn't remember what it was.

It's a lot like some people with amnesia, and like people with epilepsy.

People with amnesia have particular difficulty recalling specific situations, but they can have a general recollection of them.

For example, ask the patient to recall the scenery of a place he has visited. He said that he remembered that there were flowers, and that the flowers bloomed on the trees. But he could not name any particular characteristics of the flower. I can't say what I saw and felt on any particular trip.

Therefore, when they see many flowers, they will have a sense of déjà vu. It's just that I can't tell when or where I saw this flower.

But Su Yu knows that he is not an amnesiac patient, because of the existence of the gold-eating body and the evolution of the brain, Su Yu not only will not forget, but can also extract everything he has experienced in the past and restore it in his mind with three-dimensional images.

Therefore, he definitely did not see the possibility that Zhao Xiaoai had forgotten about it again.

Epilepsy and madness are mainly manifested as mental disorders, which are characterized by movement disorders, emotional disorders, hallucinations, fantasies, and consciousness disorders.

In this case, it is not a problem to have a sense of déjà vu with a confused memory.

But Su Yu also didn't think he had epilepsy.

So he couldn't understand Zhao Xiaoai's extremely familiar feeling.

It's not a matter of looking at one person like another, it's a strong resemblance of feeling. Moreover, this resemblance is similar to Su Yu, causing Su Yu to have a strange feeling of seeing himself in another time and space.

"It's dark, there's something strange, I need to tell you!"

"What's the matter?" The black man lazily soaked in the hot spring in Su Yu's internal space, and asked lazily.

"Well, I met a man. This person feels very strange to me, as if he is my brother, connected to me by blood. However, I feel that this person is more like another self standing there! ”

"What, you see yourself on another plane? Is there such a thing? The black ground jumped out of the hot spring, and the splash of water splashed high...... ro！。
