It is science that provides the theories since, so far, given the circumstances, it has proved impossible to find answers when it comes to death. Is it true that peace is found? Or are we going to purgatory? Do we see dominant entities? Or the memories of a lifetime that flashed by?
According to neuroscience (the scientific study of the nervous system), when we are in the gap between life and death, what we feel will depend a lot on how we die. If a sudden death occurs or one that involves intense pain, you are unlikely to experience any kind of sensation.
This is because “the central nervous system stops working and consciousness fades,” neurosurgeon Fernando Gomes told CNN Brasil. When a proximate experience occurs, the phenomenon is not the same, but it is known.
How many times have you heard of seeing the light at the end of the tunnel? For this health professional, this report “is very common.” It is the perception of “a tunnel with a light at the end and a feeling of well-being”, which will be “caused by the release of neurotransmitters”, i.e. chemicals produced by neurons in response to a stimulus or response.
When the person dies slowly, for example in cases of multiple organ failure, “what happens slowly and progressively is that the main organs, such as the brain, the heart and the kidneys, are given priority. They suffer. Over time, everything stops, as if it was a bus crashing into a pole,” he compares.
“Those inside, little by little, will also suffer a slowdown and cease to have the movement in action”continues this doctor and professor, who works at the Hospital das Clínicas hospital complex of the School of Medicine of the University of São Paulo.
There are also reports of those who have experienced something like leaving their body and being able to see themselves, being cared for, for example. This sensation is due to disturbed sleep patterns (such as sleep paralysis), where even though you are asleep, you are still aware of the world around you.
The culprit for this artificial sensation is the area of the brain between the temporal and parietal lobes. In turn, hallucinations of dead people are common “in people with neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease.”points out neurologist Felipe Chaves Duarte on CNN Brasil.
This idea of the moment of death in which “relevant memories, mostly emotional, are triggered, as if playing a movie” of one’s life “makes sense” from an “electrical point of view”, since we go through “a moment of superconsciousness” which is explained from the brain’s accelerated rhythm in conditions such as a massive heart attack.
