Old People Can Produce As Many New Brain Cells As Teenagers (independent.co.uk)
Long-time Slashdot reader Futurepower(R) shares this article about a newly-published study which counters previous theories that neurons stop developing after adolescence:
Healthy men and women continue to produce new neurons throughout life, suggesting older people remain more cognitively and emotionally intact than previously believed, researchers found. For decades it was thought that adult brains were hard-wired and unable to form new cells. But a Columbia University study found older people continued to produce neurons in the hippocampus -- a part of the brain important for memory, emotion and cognition -- at a similar rate to young people....
However, the researchers also noted fewer blood vessels and connections between cells in the older brains, which Ms Boldrini said "may be linked to compromised cognitive-emotional resilience" in the elderly.
The article suggests these newest findings may be hotly debated.
"They come just a month after a University of California study suggested adults do not develop new neurons."

Just don't want to.
Have gnu, will travel.
He's a verified traitor now.
It is and we do!
Of course we can produce new brain cells. We just forget where we placed them... Now get off my lawn!
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
We already know everything about the brain. That's why we have AI.
His signature is a joke, have you seen it lol? It looks like a failing lie detector test readout. He's going to be stamping license plates if he's lucky, but I don't think they even let them do that at ADX Florence.

But, I thought "science is settled" and 97% of scientists agree?
It is. Old people are stupid and vote Republican.
WTF?! The Parent is a Troll and deserves worse!
Wait - because the President has not publicly disclosed everything he said to a world leader, he's a traitor? So no President can ever have private and confidential conversations with other world leaders?

No one has said anything of the sort. Weak trolling is weak.
Eggzzzzzzzactly
Not "any" world leader, Vladimir Putin, the guy he colluded with, the guy his campaign had hundreds of contacts with the agents of, despite saying he had zero to Congress and the American people. The walking traitor, Drumpf.
Nice try bitch, but Trump's headed for ADX Florence. You dishonest little faggots do it to yourselves.
Wow, millennial. You do know you won't be 25 forever, right?
It won't even fit inside my skull! I call the external part of my brain "the internet". Seriously, we all use the internet as an extension of our brains. There's no need memorizing so much stuff when you have nearly the whole knowledge and wisdom of the world at your fingertips.
I prefer to use my "internal storage" for personal memories. That's nearly 66 years of friends, family, parties, relationships, neighbors, holidays, and the like. I still do math problems in my head just to keep the CPU in shape. Emotionally I'm about the same as I was long ago; just a little bit slower to anger, but that's all.
Why can a child learn a new language easily while older brains can't?
What the fuck is going on you two?
This is not 4chan
because it was soooo settled that nobody disagreed at all... yet here we are.
"His name was James Damore."
Anti trump long winded traitor go to your cell
I also made a lot of another kind of cells, I doubt old people make as many of those cells...
Last thing I expected anyone to say
Trump owns and Iâ(TM)m voting for him again
Figures you repeating all the same nonsense we heard during the election. Dumb shit. Youâ(TM)re too stupid to be alive
"most likely to end up in Federal Prison" -Voted!
He's required by law to record every communication with foreign governments. He has an entire staff there to do that. Putin had his staff, and press there, Trump blocked his. Including his own State dept head, CIA chief, his own people, his own people, people he chose, he blocked.
Instead he came back from Helsinki, and we learned.... from Russian press.... that he's agreed to cooperation with Russia in Syrian, including putting US troops under Russian command to 'fight ISIS'.... three months after Russia attacked a US outpost, and while Russia was bombing allies in Syria. Huckerbee Sanders couldn't refute it. She claims she's been briefed on what was agreed, but wouldn't refute the claims made in the Russian press.
We also learned that Russia would be allowed to investigate if there was collusion with Russia, letting them subpoena US Diplomatic staff. He literally put the Russian police in charge of the US political system.
The Republicans to their credit blocked both of these.
I get that you're a Trump supporter, or perhaps a Russian troll posing as a Trump supporter, but at some point he has to be cast adrift by the Republicans.
The only people he lies to, are his supporters who get their news via Fox News, because that's the only channel that joins in on the lies. The rest pull up the clips of him saying the opposite, or the facts and numbers. Fox news, puts up fake smiles and flat out lies to its viewers. And only his supporters among the Fox News group are prepared to suspend disbelief. Some of Fox News viewers remember the details and know they are being lied to.
If they'd been told from the outset, that he'd agreed with Putin's VTB Bank, to build Trump Tower Moscow, earnings $130 million from the deal. That VTB Bank was under US sanction, because it had a nest of spies in New York, going around property developers offering lucrative property deals in exchange for help lifting sanctions, back in 2012.... they would they have voted for him. He lied to them, Fox News repeated the lies, they had 'confirmation' and were suckered into the whole "Russian nothingburger" thing. Now we're learning the details, all the covert meetings with Russian intelligence, the money involved, the bank funding it, the Trump *SIGNED* contracts, a done deal.
And VTB Bank? Well it was the bank with the missing that "accidentally" assigned $12 billion loan to an African state. i.e. they have $12 billion allocated to bribes of foreign politicians hidden in a fake loan to an African state that was never made. $12 billion hole that is unaccounted for.

Ever wonder why Rand Paul took a fake letter from Trump to Putin? A letter he asked Trump to write in the first place? Money! Power! $12 billion plus help in getting power buys a lot of influence.
But, I thought "science is settled" and 97% of scientists agree?
Science never settles, it is only ever temporarily resident. That's why when the laws change it has to move.
Old people should be lashed together and used as a raft.
It's the lie-implausibly-to-attempt-to-defend-the-traitor hour every hour on the hour.
You're stupid, but not impenetrably so. Keep the kind of company you desire and you will be penetrated.
Once he builds that wall he will be greater than all the previous presidents combined. I mean, the statue of liberty was made by some french dude and given as a gift. What's the next wonder structure, the hoover dam? Mt Rushmore, there's not enough space there to add Donald Trump.
I mean, how many old people do you know that can still produce teenagers? Unless they already have them chained up in their basement or something.
And Kuato too.
Old people brains show signs of "compromised cognitive-emotional resilience", or as it's otherwise known "becoming immune to the world".
Science finds us something new every day.
McCain's headstone needs to be carved and used as a urinal. I'd pay to piss on it!
You're clearly the exception to the rule, AC: Your brain stopped producing new neurons a long time ago, and didn't have that many to start with either.
For instance too many people still believe that someone over, say, 40 years of age "can't build muscle" and "can't be physically fit" and "can't lose weight and will just get fat and stay fat" but that's all been disproven over and over again whether anyone wants to believe it or not -- it just requires you to be willing to do the work and suffer through the training to attain a level of fitness, lose excess weight, and so on. Furthermore this myth is perpetuated by older people who are inherently lazy to begin with, who use age as an excuse to not make the effort -- and in the process, become "crabs in a bucket" to their peers as often as not, not wanting others in their age group to better themselves, so making them look bad in the process.
So it logically follows that your brain, being just more protoplasm like the rest of your body, follows the "use it or lose it" rule: if you don't challenge your brain, keep learning new things, keep thinking, and just let it sit there being useless, of course it'll just rot away to nothing.
Also: since the rest of the systems of your body are in essence the support system for your brain, keeping the rest of your body physically fit as a lifestyle will enable your brain to function at a higher level of efficiency -- much as the featured article alludes to:
However, the researchers also noted fewer blood vessels and connections between cells in the older brains, which Ms Boldrini said "may be linked to compromised cognitive-emotional resilience" in the elderly.
Keep the support mechanisms in good working order, and your brain will likely be in better shape as you age.

Better get on that treadmill, or bike, and get into the weight room a few days a week, folks.
The day before Dad died of the effects of dementia, he was very lucid and philosophical even though he could barely control his motor functions to speak, move his head, could move one hand only slightly or any other body control. It was difficult to hear what he said, but not for his lack of trying.
Go well
