Explain the phenomenon of past resurrection

Many people experience a strange feeling like they are reliving a certain moment in the past. Scientists call this phenomenon Déjà vu.

According to Science Daily, "Déjà vu" is a French phrase meaning "seen" . Déjà vu is a mysterious, mysterious feeling about events or images that we think have been experienced or seen before. For example, a person who stepped into the house has never set foot in, but feels very familiar.

Some people believe that Déjà vu is related to spiritual experiences or this is a glimpse of life in a previous life. About 60-80% of the world's population has experienced Déjà vu at least once in their lives.

"Because the experience of Déjà vu is often unclear, it is difficult to study this phenomenon in the laboratory , " said Michelle Hook, Ph.D. at the Center for Health Sciences at Texas A&M University, USA. .

The Déjà vu phenomenon may be closely related to how the brain remembers . Long-term memory and events are stored in the temporal lobe. This brain region plays an important role in helping us recognize familiar things and phenomena.

Characteristics of epilepsy are abnormal activity of nerve cells, disrupting the electrical impulses of the brain, causing seizures.

"Clinical reports show that some temporal lobe epilepsy patients experience the feeling of Déjà vu, before convulsing," Hook said.

But what causes the healthy people to see Déjà vu? Some researchers believe that this phenomenon occurs when the brain encounters "malfunction" , causing us to confuse the current event with the past. In fact, abnormal electrical impulses similar to epilepsy may occur in healthy people. For example, hyponogogic jerk causes an involuntary muscle twitch during sleep.

The brain only needs a small amount of sensory information, such as a familiar smell, to relive details of events related to it. When experiencing the feeling of Déjà vu, the process of transmitting sensory information to the brain's memory system overcomes short-term memory, reaching long-term memory, creating a feeling of previous experience.

According to Hook, we still have many things to learn about Déjà vu and its mechanism of action.

"There is no simple answer to the mechanism of Déjà vu's operation. But with further research in the future, the mystery of this phenomenon will be explored , " Hook said.
