| Neural stem cells: color green. Neurons which neural stem cells gave the birth: yellow, orange or red (depending on the age). |
Recent research has shown that the adult brain can generate new nerve cells throughout life.

Analysis comment:
This article explains the birth of a neuron that it's seen for the first time.
It explains too that one of the areas where neurogenesis occurs is the hippocampus. It has been shown for the first time, in adults mice, the progress whereby the neural stem cells are divided and the newborn neurons are integrated into the hippocampus.
On the one hand, the study used images of in vivo photons and genetic labeling of neuronal stem cells to observe the divisions of stem cells as they occurred and so be able to follow the maduration of new nerve cells.
On the other hand, a team of scientists made a fluorescent labeling of more than 60 cells and followed their route with images taken every 12 to 24 hours for two months. This allowed them to build what would be the family tree of the different cell lineages. By looking at the cells in action and over time, the team showed how most stem cells divide only a few times before they become neurons. These results offer an explanation of why the number of newborn cells decreases drastically with advacing age.
To conlcude, this article is a success for the neuroscience. Because this opens the door to brain repair in neurodegenerative disorders.

Thanks to this discovery, in the future it's expected to be able to use neuronal stem cells for brain repair, for example, for diseases such as cognitive aging, Parkinson's and Alzheimer's disease or depression.
The scientists said that this is just the beginning of a lot of experiments aimed at understanding how our brains can form new nerve cells throughout life.
