What occurs after we die?
Scientists might lastly be ready to reply that query after they recorded the mind waves of a affected person as her life ended.
Crucially, they didn’t got down to seize this information – as a substitute it ocurred by happenstance.
Researchers in america had been working an electroencephalogram (EEG) on an 87-year-old man who suffered from epilepsy.
An EEG measures the electrical exercise of your mind and, on this case, was getting used to detect the onset of seizures.
Nonetheless, throughout the therapy, the affected person had a coronary heart assault and died.
As such, the scientists had been capable of document quarter-hour of mind exercise round his dying. And what they discovered was extraordinarily attention-grabbing.
Specializing in the 30 seconds both aspect of the second the affected person’s coronary heart stopped beating, they detected a rise in mind waves often known as gamma oscillations.
These waves are additionally concerned in actions reminiscent of meditation, reminiscence retrieval and dreaming.
We are able to’t say for certain whether or not dying individuals actually do see their life flash earlier than their eyes, however this particualar examine appears to help the thought.
And the scientists say the mind is able to co-ordinated exercise for a brief interval even after the blood stops flowing by way of it.
‘By producing oscillations concerned in reminiscence retrieval, the mind could also be enjoying a final recall of vital life occasions simply earlier than we die, much like those reported in near-death experiences,’ stated Dr. Ajmal Zemmar, lead writer of the examine, which was revealed within the journal Frontiers in Ageing Neuroscience.
‘These findings problem our understanding of when precisely life ends and generate vital subsequent questions, reminiscent of these associated to the timing of organ donation.’
Within the examine, the researchers level out that comparable adjustments in brainwaves have been detected in rats on the time of dying.
Nonetheless, that is the primary time it’s been seen in a human.
Dr. Zemmar and his group say that additional analysis must be carried out earlier than drawing any particular conclusions.
This examine arises from information regarding only a single case examine. And the affected person’s mind had already been injured and was exhibiting uncommon exercise associated to epilepsy.
It’s not clear if the identical outcomes would happen in a special particular person’s mind on the time of dying.
‘One thing we might study from this analysis is: though our family members have their eyes closed and are prepared to go away us to relaxation, their brains could also be replaying a few of the nicest moments they skilled of their lives,’ Dr. Zemmar stated.
