- Neural Stem Cells and Exercise
- [NeuroLogica Blog]
It is only recently (the last decade or so) that neuroscientists have realized that the brain harbors a reservoir of neural stem cells, even into adulthood, waiting to be recruited to make new connections. This is an important part of neural plasticity and learning. Now that we know the stem cells are there, research is underway to learn as much about them as possible, including their regulation. Perhaps they play a role in certain diseases, like Alzheimers. Or perhaps they could be exploited to treat or prevent such diseases.
It has also been learned that not all brains are the same in terms of aging. Most brains atrophy and develop pathological signs of aging…
For now we are at the basic science level in addressing these questions – just figuring out what is going on. [...] there is one thing it seems we can say now based upon existing research – exercise, both physical and mental, is good for the brain and staves off the negative effects of aging.
A newly published study looking at the regulation of neural stem cells may ultimately illuminate one mechanism behind this…
