The brain, the organ in charge of centralizing the activity of the nervous system, would continue to produce neurons until the age of 90, according to a scientific study published in Nature Medicine. Apparently, the neuronal formation called by scientists as neurogenesis would not stop throughout life, thus helping to create new memories.
This is why, for the group of experts, the generation of neurogenesis could help people recover from disorders such as depression or post-traumatic stress in the near future. In addition, it could stop the progression of Alzheimer’s and even find an improvement against epilepsy.
This process would occur in the hippocampus, the area of the brain where learning, mood regulation and memory develop. In the words of Professor Jonas Frisen, “I would say that there is a clear possibility that we develop neurogenesis in life.
The new study, which complemented the existing ones, was led by the scientist María Llorens-Martí, belonging to the Severo Ochoa Molecular Biology Centre, a research institute located in the city of Madrid, Spain.
The experiment consisted of analyzing samples of brain tissue in 58 human patients who died between the ages of 43 and 87. The results showed that all the patients had registered the process of neurogenesis in the hippocampus in the brain, causing surprise among the community.
It is in this sector of the brain, the hippocampus, that experts were able to notice this phenomenon. Moreover, the most surprising discovery was that the development of this process had even been identified in the brains of 87-year-old patients.
Another of the conclusions obtained by the experts was that with the passage of time there is a small decrease in the process of neurogenesis in humans. However, what is surprising is that this process would occur all life in a normal brain, quite the opposite of what was believed.
