Neurologists involved in the study of the brain of nine patients as they passed on have discovered surprising information on what happens to the human brain after death. According to this new study, a final wave composed of electrical activity in the brain marks death. Referred to as spreading depression, this is composed of the final activity that happens in the brain before it shuts down for good.
According to the study, it is suggested that rebooting the brain is actually possible. The researchers are introducing the idea that rebooting the brain for three to five minutes is actually possible even after the human heart has already stopped beating. This is possible to do too, apparently, even after the human heart has already ceased to show any signs of life.
The study, which expert on matters of the brain, mind, and consciousness Susan Greenfield has found fascinating, was carried out by a neurologist team, some of which hailed from Berlin’s Charite-Universitatsmedizin. They followed a total of nine patients who had devastating injuries. These patients also have been tagged with orders of no resuscitation.
What the researchers did was to analyze the electrical signals that the brains of these patients produced as they died. The researchers were hoping that this could help them find new information when it comes to the timeline involved in dying. Their efforts proved fruitful though since they indeed have established some new information on the subject.
Electrodes were planted in each of the patient’s brains. Through this, the neurologists discovered that even when the heart has already stopped beating and when there is clearly no longer any sign of life in a patient, the neurons and the cells in the brain still continue to fiction. It is only after the spreading depression happens when these neurons really cease all of its activity. However, this is minutes after the human heart has actually stopped pumping oxygen and blood to the rest of the body.
Still, researchers stipulated that the debate on whether death truly is final is still something that is up for discussion. Apparently, there are chemical changes that occur before death. This all begins though with depolarization. There has never been a method that was established before that can be used to diagnose death in the brain. There is also no way for researchers to be really certain that a person’s capacity in terms of awareness is truly lost after death.
This new research is of much importance though since it can be utilized to help determine the length of time that it is possible for a patient to be resuscitated before the damage to the brain becomes really irreversible. These finding may also, in turn, influence the strategies for treatments of stroke and cardiac arrest- something that can complement the efforts of medical experts to re-establish circulation in the body. It can also prove to be a huge factor in the debate concerning organ donation, especially after a cardiocirculatory death.
