Secondly, exercise can also stimulate neurogenesis, which is the birth of new neurons from neural stem cells in the hippocampus.

其次，运动还可以刺激神经发生，即从海马体的神经干细胞中产生新的神经元。

In fact, they found a staggering 70 percent decrease in the number of neural stem cells compared to a control group.

事实上，我们发现与对照组相比，他们的神经干细胞的数量惊人地减少了70%。

Taking a break from drinking may be the best way to promote neural stem cell growth and other factors from neurogenesis.

戒酒可能是促进神经干细胞和其他神经元因子生长的最好方法。

Some of them were attached to a molecule that signals neural stem cells to turn into neurons, while others were attached to a molecule that encourages cells to reproduce and survive.

它们其中一些附着在了从神经干细胞转化为神经元的信号分子上，而另一些附着在了促进细胞繁殖和存活的分子上。

A neural stem cell essentially grows itself, similar to how a seed grows into a plant, all it needs are the brain’s equivalents of soil, water, and sunlight.

神经干细胞本质上是自我生长的，就像种子长成植物一样，它所需要的只是相当于大脑的土壤、水和阳光。

To help make sure that it’s only Zika virus that’s causing this sort of damage, the scientists ran a third set of experiments: they compared neural stem cells infected with Zika to cells infected with dengue virus 2.

为了帮助确保造成这种损害的只是寨卡病毒，科学家们进行了第三组实验：他们将感染寨卡病毒的神经干细胞与感染登革热病毒 2 的细胞进行了比较。
