The staff of the University of Michigan (USA) conducted a series of experiments with laboratory rodents, and found out what happens to the brain after death. The results obtained from the study can explain the nature of the so-called post-mortem experience, which is described by people who survived cardiac arrest and clinical death.
American scientists provoked cardiac arrest in experimental rats and simultaneously monitored the brain activity of rodents. It turned out that in the last thirty seconds of animals’ lives, the activity of their brains increased significantly. The researchers say that the obtained data can be extrapolated to humans as well.
“We have traced the electrical activity of the dying brain and made a number of important observations that will help us understand what happens at the time of brain death on the neurophysiological level,” says neurologist Jimo Borgigin, lead author of the study. The scientist added that neural activity, which is observed even after cerebral circulation stops, can be the source of various abnormal processes that are responsible for the near-death experience.
“The level of activity of the dying brain was surprisingly high. The electrical activity of the brain at an early stage of clinical death is much more pronounced than in a normal waking state. And this phenomenon needs further study,” the authors add.
