What happens to someone’s mind when they die?
No one has the correct information in this regard. Scientists certainly have some information, but this question is still a mystery.
However, some scientists have recently conducted a study that provides interesting information about neuroscience.
The research was conducted by scientists from the University of Cincinnati and Charity University in Berlin, led by Jens Dreyer.
For this, scientists have closely monitored the nervous system of certain patients, and for this they have taken prior permission from the families of these patients.
These people were either injured in a serious road accident or suffered a heart attack.
Scientists have found that the brains of humans and animals work in the same way at the time of death.
The main aim of this research was not only to monitor the brain at the time of death but also to try to find out how one can be saved in the last moments of his life.
What we already know.
Before this research by scientists, everything we know about the ‘dead brain’ has been obtained from animal experiments.
We know that at death:
Blood circulation in the body stops and due to this the brain lacks oxygen.
In this condition, called cerebral ischemia, the chemical components are depleted, causing the brain to completely shut down ‘electrical activity’.
This brain cooling process is thought to be triggered by neurons conserving their energy, but conserving energy does not work because the fear of dying is still there.
After all this, tissue recovery becomes impossible.
In Humans:
However, this team of scientists wanted to understand this process more deeply with respect to humans.
So they monitored the neural activity of some patients’ brains. Instructions were given by the doctors not to try to make these patients conscious with the help of electrode strips etc.
The scientists found that eight out of nine patients’ brain cells were trying to avoid death. They found that brain cells and neurons continued to function even after the heart stopped beating.
For this, the cells use the circulating blood and get chemical energy and oxygen from it. According to scientists, when the body dies and the blood flow to the brain stops, the dying neurons try to use the remaining energy.
Due to electromechanical imbalance, the brain cells are destroyed due to which thermal energy is released and then the person dies.
But research shows that death is not necessarily as powerful as it is in the future.
“Expansive depolarization initiates cellular transformation and then ends, but not death, because the depolarization can be reversed by restoring the energy supply,” says Jens Dreyer.
