Adult Human Brains Do Not Produce New Neurons, Study Suggests (newatlas.com)
Rich Haridy reports via New Atlas: New research from scientists at UC San Francisco is challenging half a century of conventional wisdom by suggesting the human brain may cease producing new neurons beyond childhood. While the divisive study may prove a blow to some research aimed at birthing new neurons to battle neurodegenerative disorders, it offers a new perspective on how the human brain can adapt in later life without such a capability. The team generated its data by studying brain specimens of 59 subjects, from babies to the elderly. The strategy was to look for the presence of young neurons or dividing cells by using certain antibodies that bind to those cells of interest. The focus was on the hippocampus region of the brain, known to be crucial for memory, and a comprehensively studied area previously suggested to be a key location for neurogenesis. The results were fairly comprehensive. Young or immature neurons were identified in plentiful volumes in prenatal and newborn samples but the rate consistently declined over childhood. The oldest sample that immature neurons were found in was 13 years of age, and adult samples displayed no evidence of new neurons. The study has been published in the journal Nature.
Researchers have a hard remembering what they have said before.
so many neurons. And they're the best neurons. Nobody, I can tell you, nobody has neurons as good as mine.
Just the other day I was talking with Albert Einstein. You know Al is one of the smartest people around. And he told me he wished his neurons were as good as mine.
Even Vladimir Putin said I have good neurons. You know, if I'd had all these neurons that I have now, back when I was drafted, I probably could have come up with a better excuse than bone spurs for dodging the draft. A much better excuse. I have the best excuses. Nobody has excuses as good as mine.
I'm Donald J. Trump, and I approve of this message.
