Scientists from the Institute of Cytology and Genetics (Russian Federal Research Center), which is part of the Siberian branch of the Russian Academy of Sciences, headquartered in Novosibirsk, were able to artificially produce “mini-brains” in the laboratory. These “mini-brains” grown in the laboratory will help... Further studies are being conducted on the way different genetic traits affect an individual's cognitive functions. Russian biologists said they have been able to create 3D brain organoids - also referred to as "brain organoids" - that structurally resemble human tissue. These 3D models help in researching the extent to which damage to or turning off specific coding regions, which are part of the DNA factor of the gene, affects human intelligence. Participants in genome studies believe that human accelerated regions in genes, or (HAR elements), greatly affect On the development of human speech and complex thinking. Researchers in Novosibirsk seek to study how mutations in the (CNTN6) gene affect developmental disabilities, including mental retardation. The preliminary results of the study showed that removing (HAR elements) from the genome has serious consequences for The functions of the "mini-brain" that was developed inside the laboratory. A team of scientists, headed by Tatiana Schneider, intends to continue their studies within the framework of a research grant, because further exploration of the topic will give a better idea of ​​the ways in which various diseases are formed and ways to prevent them.
