Good news for adults: The human brain builds a new nerve cell until older

The latest medical finding shows that the human brain also develops a new nerve cell until older. This finding can be good news for adults.

Researchers have stated that there have been clear evidence that the human brain is capable of producing new neurons even in adulthood, a topic that can end a few decades.

Can the human brain build a new nerve cell until older?

The process of producing fresh neurons, which is called “neurosis”, occurs in hippocampus; A key part of the brain that contributes to learning, memory, and emotions. “Our findings end the long -term disagreement about the possibility of producing new neurons in the adult brain,” says Martha Patterlin, a researcher at the Carolineska Institute of Stockholm.

Other experts also agree with the conclusion, believing that the study has provided strong evidence of neurosurgery in adults. According to Dr. Rajio Rutan, director of the Burke Neurological Institute at the Will Cornell University of Medical University, “although a study alone cannot be a definitive proof, these data are strong support for the idea that there are stem cells and neuronal preconditions in the adult brain.”

Researchers in this study, recently published in the journal Science, explored new technologies, including single -core RNA sequences and machine learning, to examine samples of brain tissue from international bio -banks. RNA, a DNA family, represents genes activated within cells, while machine learning is a type of artificial intelligence that is often used to analyze massive data.

Since the 1960s, scientists have known that mice, rats, and some inhumane yarns produce new neurons throughout their lives in the Dente Girus. But access to appropriate examples of adult human brain tissue has always been very difficult. “The human tissue comes from autopsy or surgery, and its processing, including the duration of the pre -stabilization, can hide the type of chemicals used and the thickness of the cuts can hide fresh neurons,” says Patrilin. The use of advanced technologies allowed our team to overcome these obstacles. “

Researchers examined more than 400,000 single nuclei of the hippocampus cells from 24 people, and also analyzed the other 10 brains by complementary methods. These brains belonged to people of 0 to 78, including six children and four teenagers. Using two advanced imaging methods, the location of fresh cells in the tissue was mapping. They observed groups of prefabricated cells that were next to the completed neurons; In the same areas where animal studies are also known as the location of adult stem cells.

“We did not see these prefrontal cells in infants and children, but also in adolescents and adults,” Patrilin added. “It includes stem cells that can reproduce themselves and create other types of brain cells.” According to Rutan, new technologies allowed new neuronal cells to be identified at different stages of growth and research that was not possible a few years ago.

The research team also used fluorescent labels to marker in the proliferation cells. This allowed them to design a machine learning algorithm that was capable of identifying cells that, according to earlier findings in rodent studies, would become neuroscience stem cells. Rasan described this as a clever approach to addressing the challenges of examining the formation of brain cells in adolescents and adults.

What do the test results say?

As expected, the brain of children produced more neuronal cells than adolescents and adults. In the meantime, 9 of the 14 adult brains studied with one technique showed symptoms of nerve -proof, and all 10 adult brains studied by the second method had new cells. Regarding cases where a new cell was not found, Patrilin emphasized that it was still early to conclude about the difference between adult brains and lacking it.

Dr. W. “They were able to find the needles in the straw warehouse,” said Taylor Kimberly, head of the brain intensive care. “When we identify and investigate them and find out how to adjust them, we can follow the path of precursor cells over time and examine their relationship with diseases.”

“Although specific therapeutic strategies for humans are still under investigation, the fact that our adult brain can produce new neurons changes our view of lifelong learning, recovery from damage and impact capacities of neurological flexibility,” Patterlin said.
