The human brain also develops an aging – | Iranian and world news

Researchers have long thought that the human brain would not produce a new nerve after childhood, according to .

According to the same view, the human brain was thought to be a constant and incapable of producing fresh cells in special memory and learning sectors. But now a new study is contrary to this, and there is a very clear evidence that the new nerves in the brain of adults to the age of old age.

A team of researchers at the Carolinska Institute in Sweden have identified the formation of new Hypokamus nerves, an area of ​​the brain that is important for memory, learning and emotion regulation. In 2013, researchers led by Professor Jonas Frazen showed that the new nerves are formed in adults. They used the method of carbon -14 dating in the DNA extracted from brain tissue to find out when the separate cells were produced and create a unique perspective of neurons in adults.

Although the research showed the possibility of new neurons, there was no reason for where these nerves came from. In a new study, researchers examined and analyzed people of brain tissue after the death of infants to the age of 78 to find out that neural precursors (fully developed pre -incomes) are not only present in the adult brain, but are actively divided.

The research used advanced techniques such as single -core RNA sequences to mapping gene activity in brain cells. In this way, the researchers identify the various stages of neurological development from stem cells to immature and divided neurons with the help of fluid cytometry (a cellular method) and machine learning.

Researchers used RNASCOPE and Xenium, two powerful spatial transcription tools to visualize the place of these new neurons. These tools confirmed that the formation of the cell in the tooth torture occurs part of the hippocampus, which is associated with learning, cognitive flexibility and encryption of new memories.
