What Research Tells Us About the Birth of New Brain Cells
The above research is considered important as is suggests that there are factors that can stimulate and inhibit the process of adult neurogenesis. It even hints at possible models for treating degenerative diseases, such as Alzheimer's and Parkinson's diseases, and even reversing damage caused by traumatic brain injury.

There is a brief review of this topic in the latest edition of Nature :doi: 10.1038/d41586-019-00891-7.
According to data from Avarez Buya, NO.
Lets see the recommended latest Nature edition?
There are some research which are in favor of neurogenesis while other failed to generate the same results. It is still unclear to clarify on the base on less evidence we need more researches in future. If it is possible than the many neurodegenerative disease can be cure in future.

All of them are science divulgation most based in same publication that do not finally demonstrate neurogenesis in humans but oresence in certain regions of neurons that they call immature. Thats all no definitive proof of adult neurogenesis.
The paper mentioned by Sadanand (Nature Medicine: 25, 554–560, 2019) states "By combining human brain samples obtained under tightly controlled conditions and state-of-the-art tissue processing methods, we identified thousands of immature neurons in the DG of neurologically healthy human subjects up to the ninth decade of life." Also "These neurons exhibited variable degrees of maturation along differentiation stages." The articles says that these results demonstrate adult hippocampal neurogenesis persists throughout life in healthy individuals. It also reports that the number and maturation of these neurons progressively declines as Alzheimer's disease advances. These results do seem to suggest very strongly that new neurons are formed in the human hippocampus throughout life.

The discovery that human brains produce new neurons throughout human life is one of the greatest discoveries in neurology in the last 20 years. The idea has received enormous public and scientific attention, given that it gives a glimmer of hope that this innovative brain power can be used to enhance cognition, or to treat injuries or diseases. In animals, scientists have linked the continuous production of new neurons, improved learning and memory processes, and perhaps mood control.
Hi, Lala Behari Sukla ,
this topic is under hot debate. The last paper of Buyla’s group has rekindled the discussion, showing the absence/rarity of new neurons in the adult human brain (1), although some subsequent papers have shown a remarkable capacity of adult and even aged human brain to generate new neurons (2). There are lots of controversy about methods used to investigate this issue and we need more time, technology and effort to get closer to clear understanding about this phenomenon in humans.

The work is the latest on an issue that has divided neuroscientists for decades, with some arguing humans have their full quota of brain cells by the time they reach adulthood, and others claiming fresh neurons continue to be made into old age.
