Scientists breathed life into the dead brains
"Scientists breathed life into the dead brains"

"Scientists have managed to recreate some of the functionality of the grishjärnor several hours after grisarnas death. The findings, which are considered ground-breaking, giving hope to one day be able to transplant the brains."

"It is in the journal Nature that researchers at the Yale School of Medicine in the united states show how they have succeeded with something that brings to mind Frankenstein's monster or zombies. In the article they describe how they have developed a system, called Brainex, which mimics the perfusion or blood circulation, that is to say, the process when the blood is delivered to the extremely small capillaries, and thus to the surrounding tissues. In this way, they have managed to restore some of the features of the 32 grishjärnor four hours after grisarnas death."

"According to one of the researchers behind the study, professor Nenad Sestan of Yale University, the research shows that the intact brain of a large mammal has a previously underestimated the capacity to restore some of the molecular and cellular functions several hours after the circulation has ceased."

"No higher functions."

"The brain functions that scientists managed to resurrect are, however, that"

"Although it is viewed research as an important piece of the puzzle as previously thought that the brain is completely dead after so long without adequate oxygen and blood supply. Mammalian brains, including man, is namely extremely sensitive to decreased oxygen levels. Only after a short period of anemia will begin the nerve cells that die with irreparable brain damage as a result."

"The research that is now presented shows, however, that, at least in theory, have the opportunity to bring life into some of the features of an already -"

"Furthermore," says Andrea Beckel-Mitchener of the National Institute of Mental Health, which was one of the study funders, would the research could result in new ways of studying the brain post-mortem, that is to say after death."

"the Brain is the organ that receive and process information from the body's sensory organs. The information makes us aware of what happens around us, and then determines the brain what to do by sending out signals to the body's various organs. The brain also stores information, memories. The brain is also where our consciousness and our emotions are."

"An adult brain weighs between 1.2 and 1.4 kg and consists of about 100 billion neurons and around 1,000 billion glial cells. The brain can be divided into different parts and areas that everyone has more or less specific tasks."
