Death can be postponed?

During this time, many people believe that the death triggered by heart stopped beating so pumping blood throughout the body stops and eventually the body stops working. However, a recent study by experts from the University of Michigan nerve, Jimo Borjigin, reveal that death is determined by the signal submissions to the heart of the brain rather than the heart organ itself.

"People usually focus on the heart, thinking that if it saves the heart, the brain will also survive. You have to decide chemical communication between the brain and the heart to save the heart," said Borjigin.

To reveal it, Borjigin exposing rats to carbon dioxide, induces arrest incident heartbeat. Towards death, scientists observed the activity of the heart by echocardiography (ECG) and electroencephalography (EEG) and chemical signals in the two organs.

Borjigin reveal, after exposure to carbon dioxide, rat heart rate went down. Then, the activity of the brain adapts to the activity of the heart. At that time, compounds that trigger relaxation dopamine, and norepinephrine that trigger alertness, blood flooded.

Having sent two compounds that function as a signal that keeps the heart in rhythm with the lower chambers of the brain until the heart can not contract normally to pump blood. The condition is called ventricular fibrillation.

Ventricular fibrillation condition lead to death. When scientists inhibit the delivery of dopamine and norepinephrine, ventricular fibrillation condition can be inhibited. Finally, the death can be postponed. What can be done the same way in humans to delay death? Borjigin, as reported Livecscience on Tuesday, April 7, 2015, said, "It's a question worth billions of dollars."

Research to realize it would be very valuable. This is not to meet the desires of those who do not want to die, but to save the lives of people who had stopped heartbeat. By blocking signals from the brain, doctors have more time to save the patient. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
