When a person's breathing and heartbeat stops, the internal circulation also begins to slowly stop, and although our bodies are still involuntarily trying to maintain the functioning of vital organs and provide them with a continuous supply of oxygen, without special circumstances, we will eventually die, and that's when the research of Prof. Jens Dreier, a 52 year-old neurologist from Berlin, who focuses on what happens to the brain before and after death, begins. The 52-year-old neurologist from Berlin focuses on what happens to the human brain before and after death, which may sound like mystical science fiction, but is in fact rigorous and precise scientific research.
There have been no breakthroughs in research on the subject, as past human-based studies have relied on researchers who? come back from the dead? There is so much subjectivity in these experiences -- some people feel their souls leaving their bodies, some see light, some see themselves traveling through tunnel-like objects, and some see scenes from their lives played out in front of their eyes -- that it makes the results relatively unreliable.
A joint German-American research team led by Prof. Jens Dreier took a different approach by studying nine patients who had suffered severe strokes or brain injuries and experienced a long process of dying, and who were implanted with brainwave-observing devices and were not dead at the start of the study, which allowed the team to fully observe brain changes throughout the entire process of their lives until their eventual deaths. The brain changes were observed from the time they were alive to the time they finally died!
The brain is most sensitive to oxygen, and after 20 to 40 seconds of oxygen deprivation the brain goes into hibernation and power-saving mode, and brain activity begins to decrease to reduce energy consumption, but once the last of the energy reserves are also depleted, energy-dependent ions and voltage gradients within the nerve cells collapse, and it is known from previous studies on animal bodies that this collapse will occur in the form of an electrochemical wave known as a ? depolarizing diffusion wave? , and that this diffusion is like a water wave, and that this depolarizing diffusion is reversible until a certain point in time, implying that the death of the brain nerves is reversible for a certain period of time.
Can this happen to humans as well?A joint research team led by Prof. Jens Dreier proved ------ through a study of nine cases that it does happen. Thanks to an observer implanted in the brains of these patients, the team was able to fully study the entire process of their deaths:
Once the life-sustaining machinery is turned off, the patient's blood pressure slowly drops, the oxygen supply to the brain is depleted, and the blood flow is reduced to 20 percent of normal before the entire brain suddenly stops its electrical activity in just a few minutes.
After an average of 1 to 2 minutes of these minutes, the observer records the first ? depolarizing diffusion wave? signal appeared, which spread out slowly and diffusely like a water wave at a rate of about 2 to 5 millimeters per minute, and was observed in 6 of the 9 patients.
Jens Dreier: ?
Jens Dreier: ?We have shown that the same depolarizing diffusion waves that occur in animals occur in humans after death, and we have finally shown that the last few decades of neglect in this area, when it was widely assumed that there would be no depolarizing diffusion waves in humans after death, have been very wrong.
We have also found that depolarizing diffusion waves are reversible, and that even if a depolarizing diffusion wave has occurred after a human's death, the collapsed brain nerves can be fully restored as long as blood circulation is immediately restored to the brain to allow it to receive oxygen, a process we have reproduced many times in some of our patients, repeatedly bringing them back from the brink of death.In the past, death was judged clinically by cardiac and respiratory arrest, and then gradually changed to brain death, but the discovery tells us that death is still reversible, even some time after brain death, which gives new hope to mankind.
Jens Dreier: ? Although depolarizing diffusion waves are slow and difficult to detect with ordinary EEG brainwave equipment, and cannot be directly applied to medical treatment at this time, this discovery may lead to improved medical diagnosis and treatment in the future?
