Artificially cultivated brain? Yes, American scientists have completed such a pioneering work.
According to Softpedia, scientists at the Ohio State University claim that they have produced the first almost fully formed human brain in the lab.
This brain is only as large as an eraser on a pencil, and is as developed as a 5-week-old fetus. Of course, he doesn't have any consciousness, but scientists say that he has the vast majority of the functions of the human brain and can also express genes like the human brain.
It is reported that this human brain model is first induced by somatic cells to become immature stem cells, and then programmed to grow into brain cells. It was grown for 12 weeks in a breeding device that mimics the uterine environment.
As for why it is necessary to create such a "human brain," Rene Anand said that this miniature brain will help scientists test new drugs, and the pathogenesis of brain diseases such as Alzheimer's disease (Alzheimer's disease) and Parkinson's disease will be more More understanding.
At the same time, Anand stressed that this brain has no consciousness and will not think, so there is no moral problem in related research.
Although scientists say this, cultivating the brain is different from cultivating the heart. After all, brain activity is one of the main signs of life, and ethics is a big problem.
