It has long been believed that brain activity slows down during death, but a new study revealed the opposite, as it observed an increase in neuronal activity in the human brain during death.
The first assumption of decreased brain activity stems from the idea that cardiac arrest is accompanied by loss of consciousness, but many near-death patients have noted the opposite, and some animal studies have shown increased brain activity during this time. death
A team of researchers led by Jimo Borjikin of the University of Michigan conducted an experiment in which a significant increase in the electrical activity of the brains of rats was recorded after their death by cardiac arrest.
A study in the Proceedings of the National Academy of Sciences found similar activity in the human brain before death.
According to the siteGreat thinkingThis study was conducted on 4 comatose patients in the intensive care unit at the University of Michigan Hospital who were on life support after a heart attack in 2014.
To analyze what happens in the brain during death, Borjikin and his colleagues decided to analyze data from EEG machines attached to patients, before and after life support was stopped.
After life support machines were disconnected, two patients showed increased activity in the brain’s neurological functions.
The study reveals that taking off life support leads to an increase in electrical activity throughout the brain, and researchers suggest that this pattern of brain activity may be the reason people near death see bright white lights.
The researchers believe that the results of their study on the loss of consciousness caused by a heart attack still need further validation, and may give an indication of the mechanisms by which the brain works during the human consciousness stage in general.
