And this happens through a protein that's produced in the brain called BDNF, brain-derived neurotrophic factor.

这是通过大脑中产生的一种叫做 BDNF 的蛋白质实现的，这是大脑衍生的神经营养因子。

One big thing exercise does is it raises your levels of brain derived neurotrophic factor — BDNF.

锻炼的一个很大的作用就是，它能提高你脑源性神经营养因子的水平。

Protect yourself and your brain from stress, you release this protein known as BDNF, brain derived neurotrophic factor.

为了在这种压力下保护你自己及你的大脑, 你会释放出这种被称为BDNF的蛋白质, 大脑衍生出的神经营养因子。

He found that rats that exercise on a treadmill have raised levels of brain-derived neurotrophic factor coursing through their brains.

他发现，老鼠在滚笼里的运动提升了它们大脑中脑源性神经因子的水平。

It does this by promoting the production of a protein called brain-derived neurotrophic factor (or BDNF) , which in turn enables and improves a process called long-term potentiation.

这是通过促进一种叫做脑源性神经营养因子(BDNF)的蛋白质的产生来实现的，而这种蛋白质的产生反过来又促进了一种叫做长期增强的过程。
