A DEAD pigs brain had some of its functions restored hours after it had been removed from the animal.
Scientists were able to restore some circulation and cellular activity to the brain four hours after the pigs death, challenging long held assumptions about the timing and supposed irreversible nature of brain death.
Pigs - Brain - Meat - Factory - Laboratory
The pigs brain was taken from a meat packing factory to a laboratory where it had a special chemical solution called BrainEx technology circulated through it.
During this process many basic cellular functions, which were thought to stop and never return after death, were restored.

Senior author of the research Professor Nenad Sestan said: "The intact brain of a large mammal retains a previously underappreciated capacity for restoration of circulation and certain molecular and cellular activities multiple hours after circulatory arrest."
However, the researchers did stress that the brain did not give off any signals that were close to implying normal brain function or consciousness.
Brain - Brain
This is why the brain can only be referred to as a 'cellularly active' brain and not a living one.
Brain cells begin to die when oxygen to the brain is cut off for a long period of time and this process has long been considered irreversible.
Findings - Scientists - Brain - Way - Researchers
The new findings could help scientists study the brain in a much more in depth way and the researchers believe their work could be built upon to one day help stroke patients or enable tests for new brain therapies.

These are the processes that the human body goes through when it's no longer alive...
Livor mortis occurs when the blood drains to parts of the body closest to the ground and creates bruises sometimes referred to as the "postmortem stain"
