New Delhi: Scientists at America’s ‘Michigan University’ have made an important claim about the human brain. Scientists at this university claim that when a person goes to death, during that whole activity there is a strange activity in his brain. Just before this, similar activity was observed in the brains of animals. When his heartbeat had stopped and his brain was still working. Capturing those last moments of any human or animal is a precious thing.
A team of researchers has identified a mysterious increase of activity in the brains of people who were on the verge of death. Researchers have long been trying to understand the science of the brain and what happens in the last fleeting moments before it completely shuts down and a person dies. Previous studies among animals have shown an increase in gamma waves. Along with this, it has also been recorded in this report that the experiences of those who have come back from death after cardiac arrest have also been included in it.
To better understand what happens in the brain during a person’s final moments of death, scientists at the University of Michigan in the US used electroencephalograms (EEGs) and electrocardiograms in four dying patients before and after ventilatory support was withdrawn. (ECG) signals analyzed. All four patients were in a state of coma.
The findings, published in Proceedings of the National Academy of Sciences, show that researchers found consequential global hypoxia marked by stimulated gamma activities in two patients. “The brain is poorly understood at the time of cardiac arrest. The scientists said, ‘Although the loss of consciousness is always associated with cardiac arrest, it is unclear whether patients may have latent consciousness during the dying process.
Borjigin and his colleagues wrote in their new paper, ‘In view of this conclusion, we decided to find out about the activity in the human brain before death.’
The team reviewed cases from the University of Michigan Academic Medical Center at Michigan Medicine of patients who died in the neuro-intensive care unit in 2014. He identified two out of four fainting patients who died while doctors were still monitoring them, either from cardiac arrest or brain hemorrhage.
Electroencephalographic (EEG) recordings revealed rapid bursts of gamma waves in one part of the brain that spread over a long period of time. -Range connections in both hemispheres. It was not the effects of cardiac arrest but it was the activity before death.
