Scientists implanted a small human brain of the mouse

Implantation of organs and tissues – the thing in science is not new. Not the first day, there are so-called cortical sets. It is artificially grown brain cellular organelles, which are, in fact, “a piece of the brain in miniature.” They are used, for example, for the study of schizophrenia. But recently there has been an unprecedented experiment in which a “miniature brain” implanted mouse.

The experimental rodent in this case acted as “donor” of blood and nutrients to the small brain. It is worth noting that the artificial cerebral organelles existed before, but they lived at the same time in the laboratory no more than 5 weeks. In the current experiment, this figure was increased to 233 days. Moreover, these cells grew and developed, and after about 50 days, about 80% of implanted tissues successfully engrafted. But that’s not all: getting blood and nutrients to the organelles began to grow new neurons, including some highly specialized cells of the brain.

As mentioned, cerebral organelles are mainly used for the diagnosis of schizophrenia, but this technology can be applied to other tasks. For example, you can create cortical sets for people with brain damage or problems in the development of brain tissue and transplant the “missing pieces”.

Someone may question: did the human cells on the mind mouse? Scientists say no. The behavior of mice with the implant did not differ from the behavior of normal rodents and in a test on the memory to some individuals though, and make fewer errors, but their performance was not much different from that of normal mice.

  1. I have read a few good stuff here Definitely price bookmarking for revisiting I wonder how a lot effort you put to create such a great informative website

  2. Spot on with this write-up, I seriously feel this site needs a great deal more attention I’ll probably be back again to read through more, thanks for the information!
