Daily physical exercise keeps the brain young, mouse studies suggest. But don’t wait too long to start. The brain-boosting effects of exercise diminish rapidly after early middle age, say researchers working in the lab of Yu-Min Kuo, PhD, of Taiwan’s National Cheng Kung University Medical College. Kuo’s team previously found that young brains create new brain cells and integrate them into existing brain networks. As animals get older, however, this process dramatically slows. And this slowdown in brain cell creation is linked to impaired memory and learning. Mice that started exercise in early middle age did much better than mice that didn’t start exercising until later middle age. Interestingly, the brain changes seen in exercising mice weren’t caused by a drop in stress hormones, as some studies predicted. Instead, the positive changes came from increased production of signalling molecules that promote brain cell growth and survival.
[Granny notes:
There is a small simple photo of the brain and it [to me] looks like the inside of a cow’s udder.
Years ago, a Rancher lived on the next block and he had a small building where he dressed out his beef.
My dogs brought home a cow’s udder, just as it was cut from the cow and it, as I remember, looked like this brain photo inside.
Makes sense, the udder holds the milk and releases it, does it also make it there?
Truth is, I don’t know what the milk making process is?
LOL, the things that I still need to learn.
