“It seems to me that I have already experienced this situation …” is one of the sentences that many of us have at least once thought about it in the course of one’s life.

And this is it peculiarities to describe the phenomenon of déjà vu or of the “already seen, already lived”.
The microphones of NewSicilia spoke psychologist Ines Catania to reveal to us all that is underneath.

Mnemonic alteration or …?

“Initially the déjà vu it seemed it was due to a mnemonic alteration: the subject therefore seemed to have already experienced a certain situation because, in a corner of the mind, by mistake, a false memory was activated.
And in fact there is something true …
”, begins our interviewee.

We could talk about “emotional deception”, That is to say that the situation you are experiencingwith all its emotional correlates, ne it would recall another similar one experienced previously.

In reality, “would be the emotions of that particular experience that they would have already livednot really the experience itself “.

Several researchers identify the déjà vu as a recall of a memory that has determined that sensationstored thanks to another experience in the past: “This would also explain why it is such a frequent phenomenon in the healthy population “.

“I’m talking about a healthy population, because i early studies They were carried out on individual clinical cases affected by a particular type of epilepsy: that of the temporal lobe.
In fact the déjà vu it turned out to be one of the symptoms most present in this type of pathology and therefore more easily detectable ”, he continues.

The déjà vu in the stories of patients

Many i patient stories and the “strange” experiences of déjà vu.
In this regard, the psychologist Ines Catania wanted to share one of these episodes with us:

“I remember specifically one patient that me he told of her experience from déjà vu:

‘Doctor, one happened absurd thing! I was in the car in front of a shop with my daughter Arianna, and suddenly I notice a woman and a child, who seemed very familiar to me, getting into the car parked next to them.
‘I also saw them the last time I was here’, I tell my daughter, ‘The baby made exactly the same gestures.’ Then I noticed another woman, smoking and talking on her cell phone.
‘There was also that lady with the scarf, who smoked,’ I said to Anna.
My daughter this time, she got nervous and she told me it was unlikely that this woman could stay in the parking lot all the time and smoke.
But I swear doctor, it all seemed so true… “.

There is one explanation to this phenomenon? If we wanted to try to provide it, we should do it again to the multiple different types of studiesthat have generated someone theories.
And here the speech gets longer, but it becomes more and more fascinating.

Those considered more valid And rational I’m kind of scientific And psychologicalbut there is also no lack of type hypotheses pseudoscientific and esoteric.

Let’s see them in detail, illustrated by our interviewee who gave us a very clear picture.

Neurological theories

The most accredited theories I’m kind of neurologicalwho therefore argue that the déjà vu is the fruit of some memory trick or a its brief malfunctionwhich would not cause anyway severe brain damage.

Double memory: “It’s about the idea that an action is instantly stored in short-term memorywhile it takes a few thousandths of a second more to be remembered by long-term memory.
This disambiguation of memories creates the posting which gives the impression that it is a situation that happened in the past.
Similar to this theory, there is that of the ‘conscious and unconscious memory ‘.
Sigmund Freud spoke of déjà vu to explain, for example, the memories and experiences that remained repressed and unconscious, which manifested themselves not only in dreams but also through this phenomenon “.

False recognition: “Our memory stores any situation we witness, which can be a name, a photograph, a place, a person, an action, and so on.
THE memories but they often come sign in in manner fragmented: the déjà vu it would occur when fragments of current situations become confused and merge with fragments of memories of similar situations from the past.
The brain, in fact, he can remember somethingbut not exactly when and how it happened.
This is why there would be a sense of familiarity “.

Attention theory: “According to other studies this phenomenon would be caused by an error in the attention system, which when interrupted causes a re-processing of the information.
Basically, this very short break does instantly forget an action that just happenedwhile the part of the perception remains active only in the unconscious, thus giving familiarity but not the recovery of the complete memory.
It is very similar to the Pierre Gloor’s theory at the Montreal Neurologic Hospital and Instituteaccording to which the déjà vu happens for a momentary and rare deactivation of the system from recovery of the memory“.

Verify: “The theories that find the explanation of the ‘already seen’ in a brain bug have been denials from a experiment carried out in 2016one of the most recent on the subject, at the University of Saint Andrews in Scotland, headed by the researcher psychologist cognitive And neurological Akira O’Connor.
The study was done on 21 participants, who were ‘induced’ a phenomenon similar to déjà vu: was repeated a list of words to the participants, without naming the one they have in common.
Asked later, almost all claimed to have heard that word too, as it gave him a feeling of great familiarity.
During the experiment, instead of the parts of the brain that manage memory, the frontal brain areas were activated, involved in decision-making processes.
It was then thought that the déjà vu represent a verify that the mind goes to check the memories“.

Temporal epilepsy: “Initially, the explanation that was most convincing started from the fact that this phenomenon manifested itself more in patients suffering from this condition: among symptoms preceding a epileptic crisis of this type, in fact, there would be the déjà vu.
The experiment main corroborating this theory was carried out in 2012 from scientist Bràzdilwhich compared 113 healthy participants, some who had experienced at least one déjà vu, others who had never tried it.
One was found in the brain of the former significant loss of gray matter.
Therefore, anyone who experiences this sensation was thought to suffer from mild epilepsies without severe effects“.

Other theories

The phenomenon of déjà vu fascinates a lot, what you feel is so particular, and not yet completely clear to science, that it inspires different interpretations, even theories that depart from science and from the empirical explanation, to enter a world more esoteric.

Dreams: “The best known theory, which does not make use of scientific explanations and studies, is the one that considers i déjà vu like the act of reliving or remembering something that happened in a dream.
It seems so real and familiar to us because it happened in our unconscious while we were sleeping, therefore, we can remember something but not everything ”.

Premonitions: “According to other hypotheses instead it would not be about dreams, but of real premonitionsas if during a déjà vu we were visualizing a prophecy of what happens after a few seconds “.

Relativity: “A fascinating theory holds that the time be one convention merely Human, while the world does not always follow the logic of time.
Therefore, the déjà vu it would be one of the tools we come with brought back to reality without a conventional time“.

Reincarnation: “Several religions and philosophies refer to reincarnation and to possibility of other lives.
The déjà vuaccording to these beliefs, it would be explained how the memory of a previous life that resurfaces And it gives us a sense of familiarity, without being able to remember it completely in a conscious way “.
Is déjà vu disturbing?

Can not be doneso, explain univocally what a déjà vu isthat’s for sure, but you can try rebuildas precisely as possible, what happens in ours brain which is definitely a “complex machine“.

“I quote a phrase that I often read in clinical books: ‘It can be disturbing to experience a déjà vu: you are in one new situationbut feel in every cell that it is not.
For someone this sensation unsettling has an extra touch: you are convinced that you know what will happen next… ‘And everyone likes to know what will happen next ”, concludes our interviewee Ines Catania.
