Everyone dies, but what happens during this process is a deep mysterious mysterious, scientists begin to investigate seriously. More and more experiences in death, or NDE part of the growing area.
The 5 to 10 percent of the general population has reports of NDE memories. Assorted, people’s memories are similar: perceive from the body, seeing a passage from a tunnel and seeing a light with deadly lovas or compassionate entities. Many people describe that these memories felt like a crispy detail and “real real”.
How a person creates his mere consciousness such fantastic experiences. Scientists, however, survived from interviews with survivors, studies about animals and people who gave some psychedelic drugs. NDES has published what one of the main research groups under researching Comprehensive first neuroscientific model for phenomena.

“While a person is a very strong explanation of creating a rich experience in the crisis,” says Charlotte Martial, the main author of the Belgian neuroscience and discoveries of the University of Belgium. Published this week Nature review neurology.
Martial and his colleagues model is a step-by-step hypothesis for the conditions that create NDs. They also propose evolutionary theory why these experiences occur.
To create the model, they made a detailed review of all the studies that the authors can find NDES, to go to spiritual approaches. They also had studies about static seizures, psychedelics and dying brain. Accessories clues seemed to be some of the predispositions who had a predisposition to test NDE. It includes many of these days, as well as those who tend to sleep for the fast eye movement (REM), when Sleep is when sleeping or does not sleep without laundry.
NDES themselves is caused by a precipitar event, such as cardiac arrest, which affects the cascade of physiological stress. The authors propose that some neurons networks go to overdrive to produce high levels of specific neurotransmitters, in large brain changes. Researchers investigated various research and hypothesized ways of these systems to support different mental experiences that approach death.
People can clearly remember NDS, the authors write, is likely to be the activity of three major neurotransmitters, in memory, learning and carefully involved acetylcholin; It has a key role in the response of noradrenaline, fighting or flight, as well as attention, focus and memory; And a glutamate, other learning and memory support is also responsible for orchestrating the general function of the brain to communicate with the mutual neurons.
Beyond the guilty chemical triad, he connected a quiet and quiet feeling related to the activation of 5 HT1A recipients, as well as the transient rises of endorphins, neurotransmitters that reduce natural pain and humor, neuroturansmiscers. Often due to the lively hallucinations of NDS, the team stated the hyperactication of 5-HT2 recipients of Serotonin. Dopamine also helps the visual changed experience and gives a sense of realism.
The new model challenges the preliminary hypothesis that has not been found face to face, in the brain, naturally, NDS blocks NDS The same receptors that connect synthetic ketamine. These recipients, however, are essential to form memory, so the NDE will not be remembered with such clarity, Nicolas Lejeune, Nicolas Lejeune, and neuroraphabilitality clier and researcher at Liège University Hospital. “Instead of taking the existence of an unknown neurochemistry, we propose that NDS are created from interruptions that occur naturally in response to the events that endanger life.” He said.
The model does not count on all aspects of the NDE. Researchers did not find an explanation to make sense of bringing the past memories to live or approach from a point of return. The group has hypotheses that these features can be driven by psychological processes or biological factors to identify. More research is also necessary to identify the brain, where chemical incidents that activate NDE mainly, as Martial, 2023 studies suggests the crossroads of temporal lobes, parietal and occipital lobes Play the key role. “It is one of the main regions of consciousness,” he added.
Finally, researchers also present an idea in the way of reacting the brains. Neurochemical model, they argue, discuss other studies suggesting that NDES are The human version of the game “Dead”. Many species use this last pit after a survival effort after fighting or flight. Prog deathAnimal moves and is not given an answer to external stimuli. But he is aware of his surroundings, so if you allow it, he can escape. “Playing” Dead ‘s most evolutionary origin of death, but the world-shared experiences of life were approached. “In a sense,” Martial said the passive mechanism for improving survival in life-threatening circumstances is. “
At Jimo Borjigin University in Michigan, there was no participation in anyone, however, with some ideas presented in the new steps, which are similar to those who spark REM in the Mechanisms below NDEs. A Correlation is found Among people with Sleeping Sleep and NDAs, which is “experimental research is only a rated hypothesis,” Borjigin says.
“We don’t need hypotheses built in another hypothesis,” he added. “We are at a stage that need more physiological data.”
Martial and his colleagues recognize that their new model is the first step in creating a stronger framework, which will protect physiological data. The hypotheses located in various NDE features that Martial says, “those who will include more details for future empirical studies”.
In addition to investigating the extreme ends of human experience, these future studies can also help throw light on the mechanisms of consciousness.
