German scientists developed artificial human brain with eye in the lab, know why it is special

Scientists in Germany have created an artificial human brain in the lab. This mini brain also has eyes. Although the eyes are not fully developed. This mini brain has been developed from human stem cells. It has been prepared by researchers from the Institute for Human Genetics, Germany. Scientists say that the eyes have developed in the mini brain like those of a 5-week fetus. In the future, many new things will come out from this which will help in the treatment of many diseases.

Mini Brain is 3mm wide and the eyes present in it have cornea, lens and retina, with the help of which it is able to see light. These eyes can also communicate with the brain with the help of neurons and nerve cells. Scientists say, this retina prepared in the lab will be useful in future for those people who cannot see things.

According to research published in the journal Cell Stem, when light rays were thrown at these eyes, the signals reached the brain. This proves that what the eyes are seeing is reaching the brain. For the first time this has been seen in a brain developed in a lab.

Researcher Gopalakrishnan says, with the help of the mini brain, it will be possible to know how the eye and brain interact during fetal development, in congenital retinal disorders and by testing certain drugs on the retina.

Scientists say, in 60 days, about 314 such mini brains were prepared. Three quarters of these were fully developed. They were like human embryos in appearance. They could not survive for long without blood supply. Due to lack of blood supply, it gradually ended in two and a half months.
