The Adult Brain Does Grow New Neurons After All, Study Says (scientificamerican.com)
An anonymous reader quotes a report from Scientific American: For decades, scientists have debated whether the birth of new neurons -- called neurogenesis -- was possible in an area of the brain that is responsible for learning, memory and mood regulation. A growing body of research suggested they could, but then a Nature paper last year raised doubts. Now, a new study published today in another of the Nature family of journals -- Nature Medicine -- tips the balance back toward "yes." In light of the new study, "I would say that there is an overwhelming case for the neurogenesis throughout life in humans," Jonas Frisen, a professor at the Karolinska Institute in Sweden, said in an e-mail. Frisen, who was not involved in the new research, wrote a News and Views about the study in the current issue of Nature Medicine.
The researchers, from Spain, tested a variety of methods of preserving brain tissue from 58 newly deceased people. They found that different methods of preservation led to different conclusions about whether new neurons could develop in the adult and aging brain. Brain tissue has to be preserved within a few hours after death, and specific chemicals used to preserve the tissue, or the proteins that identify newly developing cells will be destroyed, said Maria Llorens-Martin, the paper's senior author. Other researchers have missed the presence of these cells, because their brain tissue was not as precisely preserved, says Llorens-Martin, a neuroscientist at the Autonomous University of Madrid in Spain. Jenny Hsieh, a professor at the University of Texas San Antonio who was not involved in the new research, said the study provides a lesson for all scientists who rely on the generosity of brain donations. "If and when we go and look at something in human postmortem, we have to be very cautious about these technical issues."

I should use this sig to advertise my book ISBN-13 : 978-1501515132.
There is hope all those journalists suffering from Trump Derangement Syndrome... it may be possible to find a cure by growing new neurons for them!

Yup. Seems BeauHD might be well on the sauce today =P
got em :P

Iâ(TM)m in my 30s and am doing vision therapy. My sight has gotten better in the last few months of therapy than itâ(TM)s been in my life. The doctor says itâ(TM)s not my eyes changing but the brain building new pathways. And the kicker...this process has been known to work since the 1980s or maybe longer but most eye doctors just blow it off since itâ(TM)s not laser surgery or thicker glasses.
Yea, I got yer neurons right here ya little pipsqueek. Don't you have a job? Now clear up your dog's crap and get off my lawn..
The Russians have won. They have made the world a cesspool of distrust, greed, fear and hate.
But not enough new neurons to stop double-posts on the front page, evidently.

we could find an adult!

This process happens slowly, ie. longer than 4 hours which is why reposts still happen.
So clearly he is incapable of growing neurons, or even using the ones he still has properly.
Stop the lies WindBourne.
A new low?
I defy anyone to try to prove that my brain is growing new neurons.
I'll see your senator, and I'll raise you two judges.
He might actually finally grow a brain cell with this technique.
Now, this is the weird thing. We know the people have managed to get new skills in later life. We know that damaged brains have managed to repurpose neighbouring regions of the brain. It is possible that this was done by the re-arrangement of existing cells. However, when almost every other part of the body, excepting the teeth and the lens of the eye, continuously regrows and repairs itself, what was the evidence that the brain does not?
I don't think this is a problem with science. Good science is constantly re-checking things that we 'know'. I think this is a problem with the reporting of science. Somehow 'you grow no new braincells after your teens' has become something that 'scientists have proved': it has become a meme, and now it reproduces so fast, it may never be slain.
