Human Brains Make New Nerve Cells


Lots Of Them  Well Into Old Against

Neural stem cells are in the nervous system. Which renewed and can rise to various cells. they can regenerate neurons as well as glia. Such as astrocytes and oligodendrocytes. These subjects include neural stem cell engineering, differentiation, and analysis. The new study shows the view adult human brains make new neurons. As 59 samples from 29 brains collected.

Shawn Sorrells is a senior researcher in the lab of Arturo Alvarez-Buylla at the University of California, San Francisco. He said In all of the adult samples we looked at. we couldn’t find any evidence of a young neuron,” says Shawn Sorrells. This challenges of research that new neurons continue to appear in the hippocampus.

The area where the brain involved in memory.

And emotions also calls into question claims that both exercise. So the medicine anti-depressant drugs could boost the production of new neurons in the hippocampus. Alvarez-Buylla, a professor of neurological surgery at UCSF said I’m sure that there are going to be. People who challenge our results “Gage says confident in my lab’s results.

So the new study said to measures of neurogenesis that aren’t always reliable when used. On brain tissue is taken someone who is dead. Jason Snyder said knocking down the latest findings won’t be easy. He is also the University of British Columbia who wrote a commentary accompanying the study.

Snyder commented The research is “as convincing as you can be, This is one of the best or the best of the study of neurogenesis in humans.” although the researchers hunted for specific proteins produced by neurons at particular stages of development. They have found evidence of newborn neurons in the dentate gyrus. The part of the hippocampus where neurons are born. But others say the new findings are sound. Hope so this theory will be proven true and work in the case of neurogenesis in humans.
