A group of scientists believe so discovered in the brain which could explain a key mystery: why so many people have said it his life passed in front of them a few moments before he died after going through near-death experiences.
Then analyze the electroencephalogram (EEG) of a dying human being, the international researchers found that brain waves emitted before death follow rhythmic patterns similar to those that occur during sleepwhen memories surface or when you enter a state of meditation.
Brain in analysis
According to the scientists in their study published last February in Frontiers in the neuroscience of agingthe analysis of the electroencephalogram of an 87-year-old patient who lost his life due to cardiac arrest while recording their brain activity, he revealed that the brain can stay active and coordinated during the transition to deathand even after the cessation of blood flow irrigating the organ.
The measurements after analyzing what happens before death.
Brain waves before and after the heart stopped beating gave them a chance to do so explore for the first time it reflected the behavior of this vital organ during the seconds before and after death RT.
The old man’s brain recorded a marked decrease in activity after suffering a heart attack. But they were surprised to find a increased narrow-band and wide-band gamma oscillations.
It is just a behavior similar to that recorded when one enters a state of sleep or deep meditation. Hence the suspicion that the patient had vivid visual memories of your lifea.
Ajmal Zemmarco-author of the study explained: “By generating oscillations involved in memory retrieval, the brain could reproduce a last memory of important life events just before death.”
key background
The activity in question had previously been documented in laboratory rats, suggesting that it could be a biological response present in mammals and maybe other species, please expand the post.

“These findings challenge our understanding of exactly when life ends and raise further important questions,” says Zemmar.
And he concludes: “We have been able to learn that although our loved ones have their eyes closed and are ready to go, their brains could reproduce some of the most pleasant moments they have experienced in their life.
