The Neuroscience of Déjà Vu Déjà vu: brain tricks, or predicting the future?
Even the most rational of us experience it: you'll be chatting with friends or exploring a place you've never been when suddenly a feeling washes over you: you've experienced this exact moment before. The familiarity is overwhelming, and it shouldn't be familiar at all. The sensation becomes stronger before ebbing, then completely leaves, all within a matter of seconds. Had you predicted the future? Yet, chances are, you can't pinpoint exactly when you'd experienced that premonition before. Déjà vu is a French term that literally means "already seen" and is reported to occur in 60-70% of people, most commonly between the ages of 15 and 25. The fact that déjà vu occurs so randomly and rapidly—and in individuals without a medical condition—makes it difficult to study, and why and how the phenomenon occurs is up to much speculation. Psychoanalysts may attribute it to wishful thinking; some psychiatrists cite mismatching in the brain causing us to mistake the present for the past. Still, parapsychologists may even believe it is related to a past-life experience. So what do we know for certain about what happens during an episode of déjà vu? Some researchers speculate that déjà vu occurs when there is a mismatch in the brain during its constant attempt to create whole perceptions of our world with very limited input. Think about your memory: it only takes small bits of sensory information (a familiar smell, for instance) to bring forth a very detailed recollection. Déjà vu is suggested to be some sort of "mix-up" between sensory input and memory-recalling output. This vague theory, however, does not explain why the episode we experience is not necessarily from a true past event. A different but related theory states that déjà vu is a fleeting malfunctioning between the long- and short-term circuits in the brain. Researchers postulate that the information we take in from our surroundings may "leak out" and incorrectly shortcut its way from short- to long-term memory, bypassing typical storage transfer mechanisms. When a new moment is experienced—which is currently in our short-term memory—it feels as though we're drawing upon some memory from our distant past. A similar hypothesis suggests that déjà vu is an error in timing; while we perceive a moment, sensory information may simultaneously be re-routing its way to long-term storage, causing a delay and, perhaps, the unsettling feeling that we've experienced the moment before. One characteristic is common of all déjà vu experiences: we are completely conscious that they are occurring, implying that participation of the entire brain is not necessary to produce the phenomenon. Ventral (bottom) view of the brain, showing the perirhinal (red) and entorhinal (yellow) cortices.Over the years, researchers have pinpointed disturbances of the medial temporal lobe as the culprit behind déjà vu. Studies of epileptic patients investigated via intracerebral electrodes demonstrate that stimulation of the rhinal cortex (such as the entorhinal and perirhinal cortices—structures involved in episodic memory and sensory processing) can actually induce a déjà vu episode. A study published in the March issue of Clinical Neurophysiology (link is external) analyzed the patterns of electroencephalography (EEG) signals from the rhinal cortices, hippocampus (involved in memory formation), and amygdala (involved in emotion) in epileptic patients for whom déjà vu could be induced by electrical stimulation. The researchers (from France!—who better?) found that synchronized neural firing between the rhinal cortices and the hippocampus or amygdala were increased in stimulations that induced déjà vu. This suggests that some sort of coincident occurrence in medial temporal lobe structures may "trigger" activation of the recollection system. While the cause and precise mechanism of déjà vu remains a mystery, worry not—if it happens, nothing is wrong with you. In fact, bask in the moment and appreciate the strange feeling that washes over you. Or pretend to be a fortune teller. "It's like déjà vu all over again." Graphic Illustration ( imgur.com/rPGQEQU )

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? Actually I am only exposed to deja vu twice. It was when I was on the road and saw a gas station, and suddenly I felt that I had already experienced it. I dont remember my second experience but both of these experiences are pretty trivial and nothing much special. After reading all the hypothesises above, I could hardly agree with either of these. First of all, they are all hypothesises with no proof and actual experiments no matter they are the results of scientists or psychologists. And secondly, after what I have been through, I felt that I met the gas station in my dream, not from reality or movie scenes or mismatch of the brain or something. It is completely my conjecture but I believe in my own experience.
2. Can you tell the difference between precognitive experience and Deja Vu? Well searching Google doesn't support a complete definition of "precognitive experience" so I supposed that "precognitive experience" here indicates the things that we already know or be aware of in advance. If this was the definition then there would be differences between these 2 terms. "Deja vu" is a phenomenon that suddenly happens without any foreknowledge and then it reminds us of something that already happened before. However, "precoginitive experience" refers to events which are in the orbit of our specualtion based on the presence. It is not as sudden as dejavu and not nostalgic at all.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? Since there was no scientific explanation for deja vu, the following is completely my own deduction. I think people with higher education study more, which makes their brain consist of more neurons in nervous system. This happens to travellers and movie watchers as well since they witness more than ordinary people, their memory covers lots of scenes and sights. When they observe more, they are more likely to dream of those things and make dejavu happen. I think that how it works.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? To the best of my collection, I have experienced Déjà vu once. It was when I met a girl in an evening class. The first time I saw her, it suddenly crossed my mind that I had seen this girl before. However , after chatting with her, it turned out this was the first time we saw each other. The interesting thing here is that both of us have the same Déjà vu feeling to each other. Since then, we still could not explain this familiar sensation After having read all the hypotheses above, the supposition that déjà vu is a fleeting malfunctioning between the long- and short- term circuits in the brain makes sense. It might be just a false in the brain function that causes the familiarity. In my opinion, even we ourselves make several mistakes so there is a possibility that our brain may have malfunction too. After all, all of the ideas in the article are hypotheses, we could not know exactly what is the real reason to this feeling.
2. Can you tell the difference between precognitive experience and Deja Vu? According to Oxford dictionary, “precognitive feeling” is the knowledge that something will happen in the future which somebody has because of a dream or a sudden feeling, whereas “déjà vu” is the feeling that you have previously experienced something which is happening to you now. From my perspective, precognition is nearly similar to the word “prediction”. We do not have this feeling because of familiarity but according to our intution. And déjà vu in contrast is considered as a previously familiar experience.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? Déjà vu is commonly seen in people with higher education and socioeconomic class and thoes who watch more movies and travel often since those people may have experienced more than the other. There is truly some logic to these statistic. Take those higher incomes for example, travel is a common term to them, and traveling provides more opportunities to see new locations that might trigger a sense of familiarity. This example is also true to the movie watchers as those locations may have appeared in a previously viewed movie scene. In short, the more we experience things, the more knowledge we will get; likewise this knowledge may somehow cause the déjà vu due to the similiarity

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why?
I must belong in that 40-30%, because Deja vu have never happened to me in my entire life, ever, not even once. However, I do wish to experience this "phenomenon", as I can use a little surprise once in a while. In my opinion, despite all hypotheses being so persuasive, the second theory is the closest thing to the truth behind Deja Vu. Since there has not yet been an official conclusion about this matter, an accident seems to be the most acceptable explantion.
2. Can you tell the difference between precognitive experience and Deja Vu?
Despite being both remaining quite a mystery, there are some noticable differences between precognition and Deja Vu. Firstly, it is when the visions take place that distinguishes the two. While in precognitive experience, the vision, though not necessarily going to happen, is in the future, that of Deja Vu occurs in the past, which may explain the familiarity you feel during this event. In short, it is like you seeing the future in the pasat versus you seeing the future in the present. Secondly, assuming that the visions was, or is going to be true, the former experience seems to be more useful. It is quite clear that you are better off seeing the future than knowing that you have seen what you are seeing at that time.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often?
The official information as well as data about this is still nowhere to be found. However, it may be because the people who are more highly educated or travel/watch movies more often have experienced more that those who are less educated or practice the stated activities at a lower frequency.

1. I have experience déjà vu so many times that I remember none. It occurs like thousands of times. Sometimes it may exasperate me a bit because I have to face the familiar situation but remember nothing about it, such as where it has occurred, when it has happened. It is like when I see a scene and instantaneously realise that I have undergone this scene before but I cannot recollect when it has happened in the past. Or occasionally, when chatting with friends about something, and immediately I feel that these sentences have ever appeared before. I use present simple tense to express my idea since it recurs a lot and has become part of my life. I'm partly in accord with the hypothesis that says déjà vu is a fleeting malfunctioning between the long- and short-term circuits in the brain. Researchers postulate that the information we take in from our surroundings may "leak out" and incorrectly shortcut its way from short- to long-term memory, bypassing typical storage transfer mechanisms. Though it is not the official conclusion, it is still the most persuasive out of the aforementioned statements.
2. To my perspective, precognitive experience is like you can tell the future, like you have dreamt of what will happen before it does. Whereas, déjà vu is what suddenly appears and makes you feel like you have undergone this situation before and feel that you have dreamt of it or seen it, just like you are made to feel like you're having the ability to foresee things.
3. Well, I think it is because highly-educated people are more frequent to have this kind of experience since they have to go through many things, meet plenty of people, whilst people who watch movies have experienced scenes and characters along with people around sitting in the theatre or outside of it. They will have more tendencies to have déjà vu than the other people.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why?
I have experienced Deja Vu so many times but the most memorable one is the first time I got it. According to the article, this phenomenon occurs in people between the age of 15-25 but I actually experienced it in my ten. In that afternoon, I played with my friends in an abandoned house until we were all tired and decided to take a break. Then when everyone sat on the stair, I suddenly feel acquainted with the background of the stair and the way my friends arranged positions. It was the first time I have come that house but at one moment, I thought that I had been there before, may be in my dream. Among all hypotheses mentioned about Deja vu,

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? I have encountered this strange feeling from time to time, occasionally. Most of the time it happened when I was talking with my friends or when I was going to somewhere I had never been to before. However, they are just swift experiences that I do not bear in my mind later.
Among all of the aforementioned theories, I agree with the idea that “déjà vu is a fleeting malfunctioning between the long- and short-term circuits in the brain” . It is my personal belief that our brain could sometimes make mistakes during the information transporting progress. When a new, recent piece of information comes to our mine, we could probably think that the piece is coming from long-term storage and therefore must have come from the distant past. 2. Can you tell the difference between precognitive experience and Deja Vu? Both phenomena are brought about in the present . However there is a certain difference between these two. While a precognition is an insight into the future, déjà vu is like a false memory. Precognition refers to the ability of seeing the future occurrences in the present. In particular, precognition is knowing something beforehand. On the other hand, deja vu pertains to getting a impression that this situation has taken place before in the exact way sometime in the past.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? Going on a journey gives people more opportunities to discover completely new places that might evoke a strong sensation of familiarity, especially if those locations may have been in a movie scene that they have seen before. Travelling and watching movies are most common among those with higher incomes, since people in lower class are probably too busy worrying about making ends meet and do not pay enough attention to pursue their hobbies or appreciate the art.The higher education and social status a person has, the more chances he/she has to indulge themselves in developing their hobbies. There fore, dejavu is mostly experienced by people with higher education and socioeconomic class and those who watch more movies and travel often.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? I have experienced Déjà Vu on numerous occasions, but they happened so rapidly that I can hardly recall those moments exactly. The latest Déjà vu of mine was when I was wondering in the Faculty of French waiting for the Consultation Day to commence. At that time, it suddenly came to me that maybe I had seen myself in this exact place, exact position years ago. Sometimes, I even realize that I have seen those things in my dreams. To my perspective, the hypothesis “there is a fleeting malfunctioning between the long- and short-term circuits in the brain” seem to be the most convincing. As we have undergone various moments in our lives, we could just remember the significance of those memories. Nonetheless, some of the details may remain in our psyche and only appear when we are seeing something which is relatively similar.
2. Can you tell the difference between precognitive experience and Deja Vu? To the best of my knowledge, precognition is a synonym of prophecy and prediction, which is supposedly a mysterious ability of certain people who have the premonition. Concurrently, Déjà vu is a phenomenon in which we accidentally find the uncanny resemblance with something happened to us in the past. The former may relate to foreseeing the future while the latter may somehow relate to looking back into the past without deliberation.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? As far as I am concerned, all the people referred in the question are more knowledgeable and have more experience than others. Their brains may be filled with lots of ideas and images, so they can easily recall and compare with the temporary situation unconsciously. I think that’s maybe why Déjà vu happens to them more frequently than those who experience less.

1. Déjà Vu has happened to me for millions of times but I just have vague memory of those cases. I remember one time when I was riding to school, I saw a girl wearing a black shirt. In the blink of an eye I was surprised of my idea that I had seen her somewhere before in the same shirt. However, after collecting all the data in my brain, I was sure that I did not know her and I was just under illusion because of stress. It was the time that I think I remember the most.
To be honest, I have no idea of why Déjà vu happens to most of us, not to mention how it does as I am not a neurologist or someone who cares about the way our brain works. Among several hypotheses about Deja Vu, I cannot tell which one I agree the most because I find all of them possible to be true. But if I have to choose one, the second hypothesis will be my choice since I find that it explains the phenomenon more clearly and easier to understand.
2. According to OALD, precognition is “the knowledge that something will happen in the future, which somebody has because of a dream or a sudden feeling”. Here the obvious difference between precognitive experience and Déjà vu is that the former relates to our prediction of the coming future while the later refers to our false impression that we are experiencing something that had happened to us but actually it hadn’t.
3. I am not so sure but to the best of my knowledge, people with higher education and socioeconomic class experience Déjà vu many times in their life because of the fact that they have to work a lot with their brain and are always out under high pressure. The more a thing is used, the more likely it is to go wrong so maybe that’s the reason why Déjà vu has the chance to happen to those people.
For those who watch movies and travel a lot, they keep in their memory lots of information which may be very similar, such as a racing scene or a view of mountainous area. I think it is that similarity that causes the phenomenon of Déjà vu.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? Actually, I have experienced this phenomenon even before I know it is called Deja Vu. I used to be in many places where I felt so accustomed to. Many buildings ,many roads that I had never seen become so familiar to me at a first glance. Among several hypotheses which are forementioned, all of them are too vague to me. They are concluded with no evidence to back up and seemm to rely on instinctions of scientists.Also, they are very hard to understand and be persuaded!
2. Can you tell the difference between precognitive experience and Deja Vu? An important distinction is that Déjà vu is experienced during an event, not before. Precognitive experiences,if they are real, show things that will happen in the future,not things that you've already experienced.
3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? In my opinion, the higher educational people are, the more things they put into their brains, so maybe a lot of repetitive things they encountered before but ignored, leading to Deja Vu. Similar case happens to those watch movies and travel often. on the contrary, to people who are reserved and introvert, they hardly study or going nowhere, so everything becomes new to them!

1. What is your experience with Déjà Vu? Among several hypotheses about Déjà Vu, with which do you agree and why? to the best of my memory, I experienced Déjà Vu only once which is when I suddenly realized that I have seen my dad talking to my mom about my sister . Strange as it was, the experience didn't stand out much since I reckoned it had always happened as my family's daily routine. Regarding the hypothesis, I am in favor of the quote “there is a fleeting malfunctioning between the long- and short-term circuits in the brain”. As I interpret, human brain is simply a machine that works constantly 24/7 and during the working continuous working process, malfunction is inevitable. When we receive new information into our nerves system, errors occur and that brain misinterpret that the information must come from the long term memory which is why we experience Déjà Vu.
2. Can you tell the difference between precognitive experience and Déjà Vu? I interpret that precognition similar to prediction of what happens in the future. On the other hand, Déjà vu is a more of remembering that one have experienced in the past.
3. Why Déjà Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often?
People who travel and watch movies often have more opportunities to experience new places, new scenes and get to meet more people than others. They also pay more attention to the phenomenon and think more about it when it happens than people who have to struggle to make ends meet. Folks who watch movies experience the situation through the eye of the characters or the camera which can make them think that they have been there too.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why? Astoundingly enough, I have experienced Deja Vu quite many times but in those incidents what remained in my mind were just fleeting familiar feelings. The most striking experience with Deja Vu happened about 1 years ago. When I was watching a Thai comedy movie on my laptop, I suddenly realized that the current scene and what the characters were doing in this scene had happened in my recent dream. I uttered with astonishment "Unbelievable!" and then I had to pause the movie to think about this odd coincidence. I was pretty sure that I had never seen this film before. I attempt to remember and wondered if this scene was similar to another scene in some movies I had seen. However, after my careful reflection, I admitted that it had happened in my dream and the emotions seemed to so fresh to me. I find the hypothesis "There is a fleeting malfunctioning between the long-and short-term circuits in the brain most convincing. As a matter of fact, there are many coincidences in our life. Therefore, when we first witness an event an recognize that it has a few points in common with a past event, we may draw a conclusion that we have experienced it. It is also true to the situation when we get obsessed with something. However, hypothesis is just hypothesis so I just perceive Deja Vu as a miracle of the creator.
2. Can you tell the difference between precognitive experience and Deja Vu? It is a common mistake that people regard Deja Vu as precognitive experience. As far as I am concerned, precognitive experience is our knowledge or feelings about something that we are sure it will happen in the future and in fact it happen while Deja Vu makes us feel what is happening familiar. The key disparity between 2 phenomenons is that precognitive experience is a premonition or the feelings we have got before an event whereas Deja Vu is our emotions during an event. In other words, precognitive experience enables us to predict the future instead of giving feelings about a past event.
3. Why Deja Vu is most common in people with higher education and socio-economic class and those who watch more movies and travel often? We can rank people with higher education and socio-economic class as intellectual workers whose brains have to work hard and many of them have an incredible memory. Moreover, they need to think and read much daily not only for their jobs but also for knowledge enrichment. As a result, their brains may get obsessed with something they often reflect on and whenever they happen to see or read a related thing, they find it very familiar. People who watch more movies and travel often also stand a higher chance of experiencing Deja Vu than those do less as they witness more and tend to have a fertile imagination. No matter how creative they are, movies and reality have a link. Movie lovers often let their imagination take wings and come up with many scenarios. That may be the reason why those people find an event so familiar. It is likely that it has something in common with a scene in the movie they saw.

1. What is your experience with Deja Vu? Among several hypotheses about Deja Vu, with which do you agree and why?
My experiences with Déjà vu were all not very specific. When I was in grade 1 and my house was being built, one day I was playing near the work when I realized that I had already seen the sight I was looking at that time before: a decayed old door next to a pile of bricks where a man was squatting on. I strongly believed that I had observed that scene in my dream some days before and it was so striking, which was the first time I had experienced something that now I knew as Déjà vu, that it comes to my mind whenever I hear this term again. I also experienced some other cases like that one, for examples when I traveled for the first time to another province, I felt like I had seem exactly the brushes along the road and so on. However, all of them are not are striking as the first one, which is my first experience. I agree with the hypothesis that “déjà vu occurs when there is a mismatch in the brain during its constant attempt to create whole perceptions of our world with very limited input”. In my opinion in my cases, all the images I thought that had came to my mind before I actually saw them were all related to my daily life, and what made me feel that I had saw some certain exact scene before, was a coincident combination of my experiences. For examples, at the time my house was being built, I definitely saw the pile of bricks so often as it was an essential material. And the door, which was the door of my old house, there was no reason that I had not seen it before. So the moment that I thought to be Déjà vu, was just a combination of those familiar images which happened at the same time and brought me a familiar sense.
2. Can you tell the difference between precognitive experience and Deja Vu?
Personally, I reckon that the difference between those terms lies in the vague feeling of having experienced that moment before. For instance, you travel to Amazon and come across a field of red flowers. If you have already acknowledged about the field before, you would be certain about what you see when you arrive, and the sight of it cannot startle you at all. However, if you come across the field without any pre-preparation and suddenly realize a vague feeling creeping into your mind that the scene seems familiar, of course you would feel strange, skeptical, and overwhelmed about what is happening to you. “I have never come here, how could I see this before and why is it so familiar? Have I seen this in somewhere else?” All those kinds of questions will certainly explode your mind when you face the situation that seems to be Déjà vu. 3. Why Deja Vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often?
I would say that in the case of people who watch more movies and travel often, it is because of their wide range of experience. The more they go and watch, the more situations and sights they see, which may give their brain huge sources of images and more to match with what they see the next time they come to a new land or enjoy a movie. About the case of people with higher education and socioeconomic class, as far as I know, these people do not hold much belief in something called foretelling. That is why when they experience something that they feel like they had already done before, they have no choice other than referring them to the term Déjà vu, which still has been a mystery towards scientists and psychologists.

1. It might sound strange but I have never experienced Deja Vu before. I wish I could in future but I guess it will be less interesting as now I have been provided with brief information about it thanks to your article. Moreover, as my experience for the phenomenon is zero, I can hardly say whether I agree with the mentioned hypotheses or not. However, it seems that all of the given points are not clearly backed up with evidences, experiments or that kind of scientific research so they all raise a serious doubt to me.
2. I find it easy to point out the difference between these two conceptions, which is the time of happening. While precognition is close to prediction what will happen in the future, Deja Vu is similar to remember what happened in the past.
3. In my opinion, those who have been mentioned are the people who get more chances, more opportunities to discover their surroundings than the others. Their brains are filled with myriad of memories which includes vivid imagines, sounds, smells and even feeling so I bet it may be much easier for them to recall any pieces of retention. Also, their brains are trained usually since those people get involved in many complex fields. Therefore, they will have a more incredible memory span and have no matter in collecting new experiences.

1. What is your experience with Déjà vu? Among several hypotheses about Déjà vu, with which do you agree or why? I have experienced with Déjà vu several times, but hardly can I remember these situations precisely since they all occurred just in a relatively short period of time. To be honest, I barely agree with either of the nowadays-existed hypotheses of Déjà vu since none of these were fully provided with reliable and scientific evidences. Furthermore, I really do believe in the super power of our human beings, as there have been countless researches and experiments supporting the fact that normal people just only use up about 10 percent of their brain capacity. The chances are that Déjà vu is induced by the spare room in human’s brain storing some kinds of premonitive ability rather than the malfunction in our neuron system. 2. Can you tell the difference between precognitive experience and Déjà vu? If I do understand “precognitive experience” in a correct way, there is a clear distinction between these two terms. “Precognnitive experience”, to my own knowledge, refers to a suberb and stable ability which can occur in some certain individuals. These people are the ones who fortunately possess the aptitude of foreseeing the future. “Déjà vu”, on the other hand, is merely a random cerebral event happening in such a short period of time without benefitng anyone. 3. Why Déjà vu is most common in people with higher education and socioeconomic class and those who watch more movies and travel often? I really think that Déjà vu must have something to do with human’s imagination. The more vivid imagination people own, the more tendency they encounter this cerebral event. It is obvious that people who watch movies and travel a lot would have more chances to be exposed to different sates of mind and have their creativity boosted more regularly. As about the ones who are well-educated or from higher socioeconomic backgounds, these people normally observe everthing in a very distinctive but also more inventive way compared to ordinary people.
