“A little alive.” What happens to the brain and body of man after death?
Each of us knows that sooner or later will die. But it turns out that after death the human body is able to show signs of life. Some of them seem unbelievable.
Scary and embarrassing
As stated in the medical encyclopedia, death is the irreversible cessation of vital functions of the body, natural and inevitable final stage of individual existence. In warm-blooded animals and humans it is primarily associated with the complete cessation of breathing and blood circulation.

In fact, death may consist of several stages and terminal States. And the signs of biological death (when all physiological processes in cells and tissues discontinued) with the development of medicine were constantly specified. This question is vital in the truest sense of the word. And it’s not that people can bury alive (alive in our time to imagine it but used to happen regularly) is the precise statement of death depends on when to stop resuscitation as well as to remove organs for further transplantation. That is to save someone’s life.
What happens to the body when all the life processes cease? The first to die of brain cells. They are the most sensitive to lack of oxygen. However, some nerve cells are able to live so long, scientists are not quite sure as whether to consider such a person dead? He, it seems, continues to perceive and (who knows!), might think!
Swedish scientists at the Karolinska Institute conducted a research and came to the conclusion that the brain activity of deceased varies greatly. It is around zero, which indicates death, then suddenly rises to a value corresponding to the waking state. And then falls again. What happens in the brain of the deceased remains unclear. It is not excluded that he having some thoughts and feelings even after the heart stopped beating.
Scientists suggest that nerve cells of the brain at this moment emits the last pulse. This can explain the phenomenon of emotions in a state of clinical death — the feeling of flying, the light at the end of the tunnel, meeting with a higher being, and so”it is Unlikely that the person is conscious during such brain activity. The only one who approached it, and maybe even something to tell about it, — those who have experienced a near death.Lars Wissenschaften at the Karolinska Institute
And according to believers, a flash of brain activity correspond to the time when the soul of the deceased leaves the body.
If you ask a dead man what he’s thinking — it is not possible to see the movement and hear the sounds quite real. The fact that after death the body twitches a couple of seconds, it goes into spasms. Then the muscles relax, returning to its original state, and this can be seen as a perturbation or jerking of the limbs. There were times when people gave up the Ghost, and his chest was moving, creating the impression that he’s still breathing. The reason is that after the death of the nervous system is still some time sends the spinal cord signals “by inertia”.
Sometimes the dead make funny noises which of course, plunges in horror and relatives gathered to spend his last journey. These sounds similar to a groan, a whistle, a sigh or a muffled cry. There is no mystery here: each person’s body is filled with liquids and gases. Once the body begins to decompose, additional gases are formed, which need a way out. They find it through the trachea. Hence the sounds.
It happens at all “inappropriate behavior” on the part of the dead men, when the participants notice their erection. The awkwardness and bewilderment is understandable, but understandable and the phenomenon itself. After the heart stops, the blood can move into the pelvis and lead to temporary swelling of the penis.To solve and overcome!
In the human body is inhabited by a huge number of bacteria — scientists count about 10 thousand species of them, and the mass of these microorganisms can reach 3 kg. When our last breath stops to function of the immune system, these countless hordes of “little friends” have nothing holding back. Microflora begins to devour the corpse inside. The bacteria are free to move throughout the body, the intestines absorb, and then the surrounding tissue and invade blood capillaries of the digestive system and lymph nodes. They migrate first to the liver and spleen, and then in the heart and brain.
Simultaneously with the activity of microbes is education cadaver spots — they occur where deposited in tissues staying blood. After 12-18 hours the spots reach their maximum coverage, and a few days are dull green. But it turns out that at the same time, some body parts of the deceased remain viable.
For example, despite the fact that the heart had stopped long ago, its valves can still be maintained. The fact that they are connective tissue cells that live long. So, heart valves can be used for transplantation. And this is after a day and a half after death!
