Breakthrough new research reveals what happens in our bodies the moment before and after we die.
Studies have found that brain activity that resembles meditation, dreams, or memory recalls passes through the brain at that last moment, and there may be a final sense of comfort as humans die.
“What we may learn from this study is: Our loved ones are ready to close their eyes and let us rest, but their brains are what they experienced in life. You may be playing some of the most amazing moments, “said the co-author of the study. In the statement..
A study published in the journal on Tuesday Frontier of Aging NeuroscienceIs based on one of the first records of a dying brain that happened by chance in a Vancouver hospital.
After the fall, an 87-year-old man was admitted to the facility and a neuroscientist connected him to electroencephalography (EEG) technology to detect seizures.
EEG involves placing electrodes along the patient’s scalp to measure the activity of different parts of the brain.
While the man’s brain was recorded by brain waves, he died of a heart attack, allowing scientists to find out what happened to the organs at the moment before and after his death.
“We measured 900 seconds of brain activity at the time of death,” Zemmar said. “We have set a special focus to investigate what happened 30 seconds before and after the heart beats.”
Studies of EEG records reveal that there was an increase in gamma oscillations (also known as “electroencephalograms”) in the last few seconds before the death of a man.
Gamma oscillations are involved in high cognitive functions such as information processing with dreams and extreme concentration.
Vibration is also associated with memory recovery and flashbacks — in support of the idea that “your life flashes in front of you” in the moment before death.
“By generating the vibrations involved in memory recovery, the brain may have a final recollection of an important life event just before we die, similar to what was reported in near-death experiences.” Said Zemmar.
The increase in gamma oscillations, coupled with the decrease in delta, theta, alpha, and beta waves, causes the “complex interactions” between these waves to occur after a gradual cessation of brain activity, resulting in cerebral blood flow. Canceled (after cardiac arrest). “
This suggests that the brain is active for a short period of time even after the heart has stopped beating.
“These findings challenge our understanding of exactly when life ends and generate important subsequent questions, such as those related to the timing of organ donation,” Zemmar argued. ..
New research revolves around one of the first records of the dying human brain, but similar research is being done with rodents in a controlled environment.
Researchers also discovered an increase in animal gamma oscillations in the moment before death. This indicates that the brain organizes biological responses to death that may be common among species.
The authors of the new study say more research is needed given that their theory is based on the records of only one human patient.
But they say, this peculiar study gives some hope to those who are suffering from the loss of their loved ones.
