New Haven, Connecticut, USA, 12/25/2018 (The People Online) – A group of neuroscientists from Yale University have been able to restore brain circulation in decapitated pigs and have kept the organs alive 36 hours after being separated from the stem. It is not the first time that the brain of an animal is maintained outside the body – it was already achieved in rodents – the news is that the oxygen flow in an organ of this size has been preserved intact. To be able to work on living tissue at this scale, for example, opens the door to the creation of a cerebral atlas by cataloging neuronal compounds and thus deeper in nature an organ which is in fact little known, according to El. world.
The research was presented for the first time during a meeting of the United Nations National Institute of Health (NIH) and has been collected by MIT Technology Review, based on the efforts of the main researcher Nenad Sestan during the conference. Although the neuroscientist clarified that the brain did not show any signs of consciousness at all times, he hopes that this performance will give a new impetus to several studies of experimental treatments for brain tumors or Alzheimer's.
Although the full results still have to wait a few months before they are published, Sestan and his team are known to have used a system called BrainEx, developed in the Yale laboratory to keep living cells circulating an oxygen-rich fluid through a system of pumps. heaters and artificial blood bags. In addition to the value of the experiment itself – which used a hundred pig heads, gathered from several slaughterhouses – the advance also constitutes a new horizon on ethical research questions in this area.
