EFFECT "Déjà Vu"

 Déjà Vu is lived or imagined experiences? A phenomenon that, although it is not common, we have all experienced it in some way at some point in our lives, this strange feeling that we have already been there or that we have already had an experience, even if we know what is not.

Déjà Vu is a general term for similar experiences, such as what has already been lived, what has already been felt, and what has already been seen. Why is this happening? Nobody knows for sure. Despite the interest in this phenomenon in some scientists, it is very difficult to study because most people, when they experience it, do not have electrodes attached to monitor brain activity.

Various surveys have been carried out and approximately 60% of the respondents admitted having felt it in the past. Déjà vécu is what people usually talk about. It is a feeling that we witness, say or see, we have experienced it before. Research has shown that it is more common in young people between the ages of 15 and 25 because their minds are still vulnerable to any changes in their environment.

It is fundamentally characterized by the fact that the experience that is considered lived usually contains a large number of details in common with the memory to which it relates. Dejà senti: Unlike déjà vècu, this process is only a mental process. This means that it does not have any cognitive characteristics, nor does it usually relate to the memory of the person who is going through it.

It can also be said that it can be a feeling that brings satisfaction from remembering something that has been forgotten for a long time. Visited Déjà: This can be translated as "something already visited", meaning that the process relates to knowing something completely new to the person. That is, when a place or something new is known, there is no reason to know it.

Some explanations for this are dreams, out-of-body travel, and reincarnation. When it comes to a more skeptical analysis, it is said that it is likely that knowing a place beforehand can trigger this feeling. Most researchers say that this phenomenon is a memory-based experience, so the memory centers in the brain are responsible for it.

The temporal lobes are the main factors responsible for preserving long-term memory of both events and events. Certain areas of the medial temporal lobes are also very important in detecting and recognizing intimacy, as opposed to the detailed recall of specific events. Detecting familiarity is said to depend on entorhinal cortex function, while detailed recall is related to the hippocampus.

Unfortunately, the randomness of déjà vu experiences in healthy individuals makes it difficult to investigate this phenomenon empirically, since any research on the subject depends on the subjective information of the people involved. This means that getting to the root of the cause of déjà vu depends on the perception of each person, which makes it very difficult to understand this strange and mysterious event.

But as with many phenomena that we still cannot understand, there are various theories about the origin of déjà vu. Why does déjà vu occur? There are many theories about the causes of déjà vu. These range from paranormal phenomena such as saying they come from past life memories, through prophetic dreams, and even alien abductions.

Some interpret this experience as evidence of a parallel universe. According to physicist Michio Kaku, quantum physics shows that there is a possibility that déjà vu is caused by the ability of the human brain to "wander between universes." Michio explains these "parallel universes" by comparing them to radio waves. We cannot see them, but there are hundreds, even thousands, that fill our space.

However, according to the laws of gravity, a radio can only be tuned to one station at a time. In the same way, our mind is tuning into one frequency of reality, and when that reality seems too familiar to be new, it may mean that we are "vibrating in accord" with a parallel universe. Another paranormal theory confirms that déjà vu is generated by our spirit and not by our brain's memory. It would be like a hazy memory or a forgotten dream.

Therefore, it is believed that this can only make sense if it comes from a spiritual ether. Apparently, this experience is how our spirit roots us in the present and lets us know that this is where we are destined in time and space. It is like a little reminder of awareness.

Some researchers have suggested that déjà vu occurs because of a mismatch in-memory systems that generate a detailed but incorrect memory of a new sensory experience. This means that déjà vu is triggered by a mismatch between sensory input and memory. Information bypasses our short-term memory and goes directly to our long-term memory, causing a mismatch between sensory stimuli (hearing, sight, touch) and working memory.

It makes the new experience feel familiar, even if the experience isn't strong enough to be real. Another theory suggests that familiarity-sensing neuromorphic activation occurs without activation of the hippocampal recall system. This brings us to a sense of appreciation, but without specific details.

It has also been observed that déjà vu is the reaction of the brain's memory systems to the known experience. This experience is known to be innovative, but with many recognizable elements, albeit in a slightly different setting. For example, a meeting in a bar or restaurant far from our place of residence, but with the same or very similar decor to the one that we regularly go to in our city.

It has also been observed that a subset of epilepsy patients experience persistent déjà vu at the onset of a seizure, which is when the seizures begin in the medial temporal lobe. This gave scientists some major clues for an empirical study of déjà vu. Seizures appear to be caused by changes in the electrical activity of neurons in focal areas of the brain.

This dysfunctional neural activity can spread throughout the brain, much like the shock waves generated by an earthquake. Regions of the brain where this electrical activation may occur include the medial temporal lobes. The electrical disturbance of this nervous system generates a déjà vu aura (a kind of warning) against epilepsy. On the other hand, déjà vu may also be before an epileptic seizure, it can be quite long-lasting and is not a fleeting feeling as it is in people who do not have seizures.
