People who find themselves near dying typically declare that they noticed a lightweight on the finish of a tunnel, that they felt as in the event that they had been floating on prime of their our bodies, or that they relived their lives earlier than their eyes.
The intersection of those testimonies, and the truth that they arrive from individuals of numerous backgrounds and origins, suggests a doable organic mechanism that continues to be a thriller to scientists.
in An article I printed Originally of the month, the Nationwide Academy of Sciences in the US (PNAS), researchers on the College of Michigan, USA, noticed seizures in mind exercise in two dying sufferers who had been in a coma.
The research’s lead writer, Jimo Borjigin, advised AFP that this research will not be the primary of its sort, however it’s “extra detailed than ever earlier than”.
The scientists studied the data of 4 sufferers who died of cardiac arrest in the intervening time their mind exercise was being measured by an electroencephalography (EEG) machine. These individuals had been in a coma, and their docs determined to cease therapy as a result of they may not be saved.
Once they had been faraway from life help, two of them (a 24-year-old lady and a 77-year-old lady) skilled a rise in coronary heart fee. Mind exercise additionally confirmed a sudden rise in gamma waves related to consciousness, in a phenomenon beforehand monitored by earlier research.
The brand new research goes even additional, with the researchers specializing in a bigger a part of the mind that was stimulated, the posterior area related to consciousness.
“If this a part of the mind is stimulated, it implies that the affected person sees one thing, can hear one thing, and is more likely to really feel sensations exterior the physique,” defined Jimo Borjegin, including that this space was “infected.”
However scientists aren’t positive why the opposite two sufferers didn’t present these indicators. In keeping with Jimo Borjegin, their seizure historical past could have an effect on this regard.
The researchers cautioned that as a result of the research was carried out on a really small pattern, normal conclusions can’t be drawn. For the reason that sufferers had been useless, it could by no means be recognized whether or not they had visions or not.
