New Haven, Connecticut, United States, Dec 25, 2013 (People Online) – A group of neuroscientists from Yale University managed to restore circulation to the brain of hung pigs and keep organs alive 36 hours after separation from the body. It is not the first time that the animal's brain remains alive outside the body-it has already been achieved in rodents-a novelty is that the flow of oxygen into an organ of this size is preserved intact. Being able to work on living tissues on this scale opens the door, for example, to the creation of a cerebral atlas by cataloging neuronal connections and thus deepening in nature, an organ from which, in reality, very little is known , according to El.

The survey was first presented during a meeting of the National Institute of Health of the United States (NIH) and was collected by the MIT Technology Review, based on the intervention that main researcher Nenad Sestan made during the conference. Although the neuronist clarified that the brain at any time shows no signs of consciousness, he hopes this achievement will give a new impetus to several studies of experimental treatments for brain tumors or Alzheimer's disease.
Although full results still have to wait a few months before it is published, it is known that Sestan and his team used a BrainEx system developed at Yale Laboratory to keep alive cells circulating oxygen rich in fluid through a system of pumps, heaters and bags with artificial blood. Beyond the value of the experiment itself – which used one hundred pig heads, collected from several slaughterhouses – the advancement also represents a new horizon for ethical issues of research in this field.
