The brain is made of soft nervous tissues which control all body functions. In order to reduce the chances of permanent or anoxic brain damage in … Through a delicate, complex process they were able to keep the brains alive by connecting them to a closed-loop system called “BrainEX” that pumps oxygen-rich artificial blood through the necessary areas of the brain to sustain life. It is possible, kind of, sort of. Instead, viruses have to invade a living cell and hijack its genetic machinery in order to reproduce. You can even lose large chunks of vital organs and live. Rare cases such as this show up that ignorance. The problem is that, without an attached body, the health of the brain can only be assessed in a fairly basic way.

Researcher Nenad Sestan, who lead the team of Yale University scientists, disclosed the nature of the research in a meeting at the National Institutes of Health last month to discuss the ethical concerns surrounding edge research with the human brain. So the jury is still out on whether its possible for a brain to “think” without a body. In essence they were able to successfully remove the pigs’ heads and resuscitate their brains while no longer connected to a body. The team did express concerns over the ethics of the situation. This could lead to a radical enhancement of our understanding of the human brain. The research itself is remarkable and, if it’s as legitimate as it’s been made out to be, it could change everything. By keeping the pig brains alive, they’re able to study them in ways that will contribute to further breakthroughs. Another four to six minutes without the brain receiving blood will result in increased brain damage, coma and then death. Occasionally, the brain can last longer without oxygen before brain damage becomes severe, but this usually requires very specific circumstances.
