Kentucky, USA: Scientists, after analyzing the brain activity of a dying person, have said that lifelong memories may quickly 'rewind' in the brain while dying.
The accident happened at the University of Louisville Hospital, Kentucky, when an 87-year-old patient was brought in with severe epileptic seizures.
In an effort to save the patient's life, doctors attached an EEG device to his head to monitor his brain activity.
The hospital staff could not save the patient's life because he had a sudden heart attack. But the EEG device also recorded his brain activity in detail for several hours during this time.
These included the 15 minutes when the patient's heartbeat stopped and his brain was struggling to survive.
An international team of doctors led by Dr. Ajmal Zimmer, a neurologist at Louisville University, closely examined the patient's EEG recordings in the last few minutes.
The analysis revealed that at the time of his death, a number of activities were going on simultaneously in his brain. However, most of these were brain activity called "gamma oscillations".
They can be thought of as "waves" that arise in the brain, especially those that occur while remembering an event or dreaming.
Considering these extra gamma activity in the brain of a dying person, scientists have suggested that perhaps just before death, our brain tries to explore the memories stored throughout life very quickly, in just a few minutes. ۔
"It seems that just before we die, our brains refresh our most important memories," said Dr. Ajmal. People passing by have been telling.
In this study, published in the latest issue of the online research journal Frontiers in Aging Neuroscience, Dr. Ajmal and his colleagues point out that this is certainly the first research of its kind, but it has many technical weaknesses. There are also.
For example, the patient was given a variety of life-saving drugs, including epilepsy and heart medicine. Even at the time of his death, the patient was under the influence of these drugs.
"Therefore, this research should not be considered as final, decisive or final, but it is only a preliminary assessment which needs further research to check its accuracy," explained Dr. Ajmal.
