Death

In 1926, a member of the Royal Geographical Society, Sir William Barrett, The published work on the visions of dying. Collected by it the general public learned that before his death people are watching other worlds, hear the music and often see dead relatives.But only in the early 70's of the XX century, American professor of philosophy and psychology, MD Raymond Moody was one of the first medical professionals who took up the little-known phenomenon of the study, which was called by him "near-death experience." According to the research scientist published in 1975 the book "Life After Life". Immediately after the publication it became a bestseller. Suffice it to say that by the end of 1999, sold over three million copies of the publication. The facts stated in it radically change all preconceived notions about the person's death.The book analyzed 150 accidents feeling trapped in a state of clinical death, but then returned to life. Recall that clinical death is reversible stage of dying, which runs for several minutes after the cessation of circulation and respiration. Duration of stay of the person in this state at normal body temperature is typically less than 8 minutes in the cooling conditions may slightly lengthen. During resuscitation (Latin re - re + animatio - recovery) human activities can be derived from the state of clinical death and return to life.Raymond Moody found that the near-death state, people feel peace, out of body experiences, flying inside the "tunnel", the approach to the light source, and more. Printed work Americans gave further impetus to the followers in this direction.Of course, scientists have tried to give a scientific explanation of the phenomenon. As it turned out, not only the dying experience similar range of emotions. Similar visions are typical, such as drug addicts after taking LSD, the people involved in meditation, patients with epilepsy. They were not in the arms of death, but have seen the end of the tunnel and its light.The well-known American scholar, Chairman of the International Association of Transpersonal Psychology, Stanislav Grof, MD and John Halifax hypothesized: a flight departing from the life of a tunnel - none other than the "memory" of the first moments of birth. In other words, the movement baby through the birth canal during birth. The bright light at the end - it is the light of the world, which gets little man.Another hypothesis suggested neurobiologist Jack Cowan. According to the researcher, the tunnel vision of a dying cause parts of the cortex of the brain that are responsible for processing visual information. Effect dizzying flight through the tube occurs when brain cells die from lack of oxygen. At this time in what is called the visual cortex of the brain waves appear excitement. They are concentric circles, and perceived by the person as a flight through the tunnel.In the late 90's Bristol University researchers managed to simulate on a computer the dying process of the visual cells in the brain. It was found that at this point in the mind every time a picture of a moving tunnel. So Susan Blackmore and Tom Prosyanko confirmed the rightness of the hypothesis D. Cowan.There is also a theory that the "post-mortem" vision caused by the fear of impending death or a drug is administered to the patient.And yet, in spite of the persistent attempts of scientists to understand the phenomenon, a number of phenomena has no answer. Indeed, as, for example, to explain the fact that the person is unconscious, is able to see what is happening around him? According to some doctors, intensive care, patients often returning from "the other side", details the actions to physicians with their lifeless bodies, and even that took place to be at this time in the neighboring houses. How to explain the incredible vision? Answer by science could not give.
