Right away, more or less people experience déjà vu, the feeling that they have experienced something before. The following article about this phenomenon is based on the latest scientific research has just been published in the journal Grunge.com.
About déjà vu
According to Wikipedia, Déjà vu is the French word, meaning “seen” or known as hallucinogenic memory or promnesia (dementia) is hallucinogenic, feeling familiar (as seen, experienced in memory) in a new setting, never known before or not remember when. This is the experience of a sure feeling of having witnessed or lived through a situation that has happened before, even though it is not possible to know with certainty when those premonitions occurred. The term Déjà vu was named by a French psychic expert, Émile Boirac (1851-1917), as he stated in the book L’Avenir des sciences psychiques, which was born when Boirac also a university student. Déjà vu is often a very familiar, but “strange and mysterious” feeling, occurring frequently in dreams and in real life, in both adults and children. Déjà vu has been described in literature for a long time, but it is a topic that causes a headache for scientists, especially psychologists today. Recently, researchers have discovered a way to create this feeling through hypnosis. From the late 20th century, déjà vu has been studied deeply in psychology and neurology. Scientifically, the most accurate explanation for déjà vu is not that it is the “foresight” of the action or of the “foreseen” talent, but an anomalous defect of memory that keeps humans from creating. gives the impression that the memory is “being recalled”. 
The Déjà vu phenomenon can take place both in real life and in dreams There is also an opinion that in the process of daily life and communication, the human brain has the ability to arrange, link events and analyze logically, thereby creating images and sounds. …, likely in the future and recorded in memory, this is almost identical to the method of prophecy. This human brain’s ability to self-align and connect is formed and trained during deliberate thinking and speculation (such as betting on something). So, when we come across one of the things the brain has properly analyzed (there may be some false positives, this explains why only sometimes we come across déjà vu), then we will feel “as if” met or been in that situation in the past. Some assumptions and facts related to déjà vu 1. Déjà vu is deceived by the senses? There is a particularly vague theory, that déjà vu is a simple phenomenon in which the senses in the body “play pranks” on people. Usually, human feelings and perceptions of the world are not distinct, in which the senses play a key role. For example, when we walk into a strange bakery, we smell the delicious aroma of freshly baked cakes. Perhaps it matches the same taste as it has been smelled before, the brain is trying to recall the exact taste, it feels as if you’ve seen it before. The above phenomenon is similar to when we hear a specific noise or a certain conversation tape, it feels like we have heard in the past without being able to recall, all of these phenomena are convincing. that the subject has experienced this moment. It is the simplest and easiest to understand hypothesis, and like most of the other assumptions about déjà vu, the senses in the body have “prank” on humans with practically no way to test. OK. 2. Is Déjà vu a simple cataloging error? Another theory is that the brain’s long and short-term memory circuits may be subjected to an issue that causes the brain’s librarian to malfunction, creating simple cataloging errors, like editing errors. 
If the brain is damaged, the insider is very common to déjà vu Let’s say you’re going to a party in a luxury apartment with brand new people you’ve never met. However, when you enter, you are overwhelmed with the feeling that you have been at a time similar to what happened before. The interior layout of the room, the number of musicians playing, everyone happily with a glass of wine in hand … you will be convinced as if you have experienced before in the past, it is déjà vu is taking you into the game. What happened makes us feel déjà vu, your brain is not doing its own function well. The human brain has a hard-to-clean memory system, which is a series of storage transformation mechanisms that, like almost anything else in the world, sometimes make mistakes. The brain can store new information when you join a party, but it does so into long-term memory catalogs, giving insiders the feeling that this event has happened, sometimes during the process. distant past. 3. Human memory is not good One prominent and quite basic theory is that human memory is not good. Concerning this hypothesis, news site Smithsonian.com Take an example from Colorado cognitive psychology professor Anne Cleary to explain. Suppose, you are taking a trip to Paris for the first time and visiting the Louvre. When you stare at the glass pyramid, people get a familiar feeling déjà vu, even though you have never been to the Louvre before, why is this phenomenon? Chances are your brain may not be able to find vital memory, which might explain why the Louvre is so familiar. Perhaps, as Cleary pointed out, if you had seen the Da Vinci Code a few months ago, which mentioned the pyramids and in the same case, it feels as familiar as one. something has been seen before. Actually, the memory is not good, doesn’t make the exact distinction. Another phenomenon that arises déjà vu is because parts of the brain work out of sync. The Rhinal cortex region that is responsible for activating the familiar activity sometimes malfunctions like an electronic device. It is activated without waking up the other memory processing areas to work together. That may explain why it is so difficult to describe the feeling when meeting déjà vu, it is often a vague familiarity, but not focused on a particular object or object. 4. Déjà vu is a manifestation of epilepsy On the lesser-known side, people with epilepsy experience a more familiar and more frequent feeling of déjà vu than people without the disorder. According to research, many people with epilepsy report a feeling of déjà vu before the seizure begins. In fact, the link between epilepsy and déjà vu has been mentioned since 1888, although human medicine was back then, did not know how to examine the brain and what about déjà vu is still very much. primitive. Specifically, the medial temporal lobe is considered the culprit, this is the part of the brain involved in sensory perception, speech language creation, and memory matching. During epilepsy, neurons are blocked, resulting in a mess of messages that are passed around the body. Déjà vu can be the result of a nerve cut across the face, the culprit causing epilepsy, and once nerve overlaps are the cause of déjà vu. 5. Chronic déjà vu is caused by brain damage Chronic déjà vu is a serious disease and also a form of proving that the neural mechanism is the culprit of the “back against” déjà vu recurrence. In extreme cases, people with chronic déjà vu often refuse to read newspapers or watch television, because they always feel like they’ve read or watched everything before. Even the act of going to the grocery store is a pain for this group of people, because it is impossible to distinguish which items have been bought and not purchased. In such cases, déjà vu overcame the interesting threshold, happened randomly and became a true disease. And, like most diseases in medicine, it must have a specific cause. Researchers have found that people with chronic déjà vu experience brain damage, especially those in the temporal region or the anterior area. Because blood vessels involved in memory and familiarity are damaged, and often disabled, patients often feel déjà vu, even making their daily lives difficult. than. BS.
