Why are human brains the biggest? We would like to inform you that human brains are not the biggest compared to other animals.
Pig brains have been kept alive outside of the body for up to 36 hours. For the first time, scientists in the US claim they were able to keep pig brains after the animals had been decapitated. Scientist Dr Nenad Sestan, who led the Yale University team, revealed his methods in a meeting at the National Institutes of Health in Bethesda, Maryland on 28 March. “Using the system of pumps, heaters and bags of artificial blood, Prof Sestan described how billions of individual cells were found to be healthy and capable of normal activity after circulation was restored to the pig brains” indicates msn.com. Sestan reports that there is no evidence of regained consciousness or electrical activity in the animals. That could be an irreversible condition of death or perhaps altered in a better experiment. His team didn’t attempt to reintroduce electrical activity.
“That animal brain is not aware of anything, I am very confident of that,” Sestan is reported. “Hypothetically, somebody takes this technology, makes it better, and restores someone’s [brain] activity. That is restoring a human being. If that person has memory, I would be freaking out completely.” Professor Sestan added: “People are fascinated. We have to be careful how fascinated.”
Currently, those hoping to delay their life after death have resorted to having their bodies cryogenically frozen, in the hope medical science will be able to bring them back to life and cure their conditions at some point in the future noticed the msn news.
The direct application of this research is the ability to study the brain in a new way. It could lead to an important improvement in their understanding of the connections between different regions of the brain. However, once the work is published, more will probably be revealed about what can be achieved with this technique.
