What is the research evidence (mechanism of action) that the "human brain" keeps working after the "heart" dies?

Dear Dennis!
As a scientist I will say that this is not possible. The brain is most sensitive to ischemia. Even a decrease in cerebral blood flow by 20% leads to the appearance of cerebral symptoms. Therefore, I think your question is from the future. Till...
Researchers had previously thought that brain activity ends before or shortly after the heart stops beating, although two studies last year demonstrated that genes continue to function, in some cases more energetically, in the days after people die. The brain can survive for up to six minutes after the heart stops. If cardiopulmonary resuscitation (CPR) is started within six minutes of cardiac arrest, then brain may survive the lack of oxygen. After about six minutes without CPR, however, the brain begins to die.
The authors of the new study, published in the Canadian Journal of Neurological Sciences, say the fresh discovery raises ethical problems as to when it is appropriate to remove donor organs in patients who appear to have died.
The Canadian doctors reported observing seeing “single delta wave bursts” in the brain of a patient after the cessation of cardiac rhythm and arterial blood pressure. The human brain can continue functioning for more than 10 minutes after the body has died, scientists have discovered. Only one of the four people studied exhibited the long-lasting and mysterious brain activity, they pointed out, with activity in most patients dying off before their heart stopped beating.
However, all of their brains behaved slightly differently in the minutes after they died.
The study authors say they have no idea why one of the brains might have continued partially functioning so long after clinical death.
Minutes of brain life are unlikely to help anything ... Therefore, from a practical point of view, it is useless. From a scientific point of view, it is interesting. More research is needed ...
Dear Dennis Mazur,
Yes, for some time, certain centers of the brain work after the heart stops. When a person loses consciousness in an accident, for a while, from several to several minutes, many different brain centers still work. It is confirmed by the facts of restoring life and health of people after accidents, which were restored heartbeat actions and consciousness after an accident. However, the issue of what people remember after experiencing what is referred to as clinical death is already a more complex problem to research. In this matter, there are still many questions to which we do not know the objective answer that would be the result of confirmed scientific research. In my opinion, what happens in the situation of ceasing the heartbeat action and decreasing oxygenation of the brain, i.e. the sensations appearing in the consciousness, images, feelings defined as the remembered effect of clinical deaths of people who, for example, survived an accident and were brought back to life it is like many other biological, psychosomatic, intelligence, etc. features of millions of years of evolutionary processes. However, how it will be interpreted and explained depends on the one hand on the lack of scientific knowledge, many questions for which we do not know the answer yet and on the other hand cultural differences, social, individual knowledge and education resources, personal experience, etc.
I don't think so because the brain coordinates with the heart and keep a soul active. Thus, it dies along with the heart. However, I would love to read any recent scientific investigations that prove otherwise.
I've read somewhere that they found some brain impulses for several minutes after the heart stopped.
Segregation of neural network from human body (FBT) may have answer.
Traditionally person is dead if heart stop working.....
