Why it feels like “Someone is watching you”
Almost everyone has a familiar experience: Sometimes when people are in a new scene, they have a few seconds and feel that they have fully understood or experienced it.
Have you ever felt familiar to a stranger?
Have you ever experienced the “soul out of the trick”?
In fact, these may be “ghost tricks” played after the brain made a mistake.
Scientists have recently studied several brain illusions, such as “familiar acquaintances,” to uncover the mysteries.
1 Deja vu: Almost everyone has a “probably acquaintance” experience: when people are in a new scene, they will have a few seconds and feel that they have fully understood or experienced it.
It is a sound, a taste or a momentary scene, which may arouse the feeling of recollecting a person.
What happened to this phenomenon?
Recent research has shown that this is a region in the brain called the hippocampus that “worked”.
Takane Tone, a biology professor at the Massachusetts Institute of Technology, has recently specifically studied some specific nerve endings in the hippocampus of the brain.
When the rats were cut off this part of the nerve endings, they reacted in the same way as they did in a room they had never been to before, and they had the same response when they were in a room that was only slightly different from the usual room.These experimental mice cannot distinguish between similar scenarios.
The hippocampus is located at the center of controlling learning and memory activities, and is mainly responsible for forming and storing long-term memory.
In fact, memory is a group of brain cells linked by powerful chemistry.
Arousing a certain memory is equivalent to finding a specific brain cell population and activating it.
Hippocampus can help us find the same or similar memories in memory based on current experience.
Once found, the current impression is considered to have occurred or recognized as a typical, familiar sensation.
Sometimes the hippocampus also makes mistakes due to negligence: they attribute the current perception to the feelings that have happened, even if this “memory” has never happened, so they have a “pre-acquaintance” like the memories of previous lives.
2 Mirror tactile sensation: Some people can feel the pain of others in particular.
When they see a pair of lovers embracing each other happily, they also feel that they are being embraced; when they see the protagonist kicking the bad guys in the movie, they will feel the pain.
Studies have found that “mirror touch” is the foundation of the ability to “empathy” (meaning empathy for empathy and empathy).
During the test, the researchers applied a real force to the specular tactile test group and the control group (people without specular tactile sensation)-it may be the same location as the other people’s touched location, and may not be the samepoint.
The results show that if the sites are the same, people with strong tactile mirror reflection can quickly and accurately report the touched sites; when their own touch with others occurs at different sites, people with strong tactile mirror reflection willTo confuse the two, think that touch has occurred in both places on his body, but people who don’t mirror the tactile energy will not be confused.
Ward believes that people with strong tactile mirror reflections are not much better than ordinary people in “knowing” other people’s feelings, but their visual empathy is spontaneous, not subconscious.
People’s feelings are essentially triggered by nerve cells.
For those who have a strong tactile sense of specular reflection, their nerve cells are overly sensitive and can be triggered not only by touch but also by vision.
3 Souls come out People often hear the story that a heart patient said that after a heart attack, he saw himself floating in the air and watched medical staff rescue him.
The latest published research results confirm that the “dead experience” is a biological experience with scientific basis.
Asura, a neuroscientist at the University of Medicine and Dentistry of New Jersey in the United States, recently completed a DIY (do it yourself) “soul-out” experiment.
He first put the two mirrors together face to face, so that the same image in the mirror could be infinitely reflected, and then he stood in the two mirrors and tilted his head slightly so that he could not see his eyes in the mirror.
At this time, if you hit his chin with his hand, you will feel that another stranger’s chin was hit in the mirror.
Asura explained that this feeling arises because the brain cannot recognize the face in the mirror as its own.
Studies have shown that it is important that the brain receives sensory feedback correctly.
Among the functions of hearing, vision, smell, touch, taste and balance, if one sensor “reports” to the brain is different from the other sensor “reports”, the brain will be at a loss and may cause something like “The soul is out of touch. ”
4 Someone is watching you!
Some people sometimes have this weird feeling: they feel that someone is staring at themselves behind, but they obviously stay in a room alone.
A neurologist at the Swiss Federal Institute of Technology in Switzerland studied a patient with epilepsy and found that if the female patient’s brain was stimulated at the left temporal parietal junction, she suddenly felt someone staring at her.
The “person” behind was sometimes sitting silently, sometimes he stretched his arms towards her.
This female patient has no history of mental illness.Therefore, scientists speculate that this strange feeling is caused by the stimulation of the electrode in the upper left-top junction area of the brain.
The top junction area is a part of self-awareness, integrating the senses of hearing, vision, touch and other physical senses, so as to synthesize where you are and what you are doing.
Blank believes that electrode currents interfere with the integration of these physical information, causing female patients to have the illusion of ghosts behind them.
The findings may explain why patients with schizophrenia always have inexplicable hallucinations, and help scientists better understand “psychotic symptoms such as paranoia and persecution.”
