Many people are afraid of death, so most of them prefer not to think about the last moments of their lives. However, what exactly do you feel before you die? Chances are that researchers have now found an answer to one of the great questions of human life.
Those who have experienced these sensations have stated that before the punctus terminus of life, everything turns into tranquility and peace, but thereafter everything is shrouded in scientific mystery. Researchers, after decades of experiments, continue to spend a lot of time researching this last moment of a person’s life.
Several hypotheses have arisen based on anecdotes, memories or animal studies. However, a new answer has appeared on the horizon of science, bringing researchers ever closer to being able to give a concrete answer in this regard.
Professor of psychiatry and neurobehavioral sciences Dr. Bruce Greyson of the University of Virginia says those final moments of death are difficult to study in real time. Apart from things that occur on a physical level, death being associated with a painful thing, the brain tends to stop that feeling of pain.
Of the many such episodes experienced, most count situations like seeing loved ones again or seeing a light at the end of a tunnel. Also, bodily sensations would be similar to leaving the body and floating.
Ante-mortem brain scanning has come up with a new answer, and the research, published in Frontiers of Aging Neuroscience, measured the electrical signals produced by the brain in an 87-year-old man who died of a cardiac arrest.
Thus, according to the researchers, the 15 seconds before cardiac arrest occurred, the EEG recorded high-frequency brain waves that are believed to play a role in the creation and retrieval of memories.
“We have signals right before death and right after the heart stops, like what happens in healthy people when they are dreaming, memorizing, or meditating,” Dr. Ajmal Zemmar, lead author of the study, told Business Insider.
The peace and tranquility you feel before you die explained by scientists
Dr. Greyson also stated that when people recall such an experience, the brain shows increased activity in several parts of it, such as those responsible for memory, vision, hearing and emotions.
Researchers believe that the temporal lobe, responsible for processing sounds and memories, has a connection with out-of-body experiences when the body is nearing death. Thus, some scientists are of the opinion that these “are simply biological and chemical reactions of the brain.”
In the case of research carried out on animals, more specifically on rats, it showed that the positive experience of those moments that people live could have an explanation in the release of a considerable amount of serotonin released by the brain.
So this would be the brain’s way of preparing the body for death by inducing feelings of peace and quiet, but also relieving pain. Regardless of the corner of the world, people’s stories are quite similar, regardless of people’s cultural or spiritual beliefs.
