Whether the adult brain can regenere neurons is controversial

with age, people often lament the passing of the years, the brain becomes bad. So, from the point of view of brain cells, are brain neurons being used less or even less likely to regener? The issue has recently returned to the fore in the scientific community, as a new study suggests that even in their 80s and 90s, the human brain is still forming new neurons.
based on a paper published in the new issue of the British journal Nature Medicine, Spanish researchers analyzed brain tissue samples donated by a group of people between the ages of 43 and 87 and found new neurons. The number of these newborn neurons did decline with age, with the oldest of the study samples 30 percent lower than the youngest.
has long been debated in the scientific community about whether the sea mass, which is particularly associated with functions such as learning and memory, can regenerate neurons as adults. Analysis of brain tissue samples donated by some of the deceased or those who underwent brain surgery showed that newborn neurons could be found in the mematic body of the child's brain, but not in adult brain samples, according to a weighty paper published last year in the British journal Nature.
the conclusions of the two studies are different, with some speculating that different results may have resulted from different tests. The authors of the new paper, Maria Laurent-Martin of the Severo Ogoa Center for Molecular Biology in Spain, said that if brain tissue is kept in chemical agents for too long, newborn neurons may not be detected, and they analyzed samples taken within 24 hours of the donor's death.Sean Sorrells of the University of Pittsburgh, the author of the
Nature paper, argues that Laurent-Martin's view is unconvincing because two of the brain tissues they analyzed in the sample were also not detected in brain tissue that had been preserved in chemical agents for only five hours. Sorrells also believes that the DCX protein labeling method used in the latest study does not ensure that newborn neurons are detected in adult brain tissue.
the new issue of Nature says the scientific debate will continue. If future research confirms that neurons can also be regenerated in the adult brain, it could help develop new treatments such as Alzheimer's disease, which is linked to the death of neurons in the brain.
