Our study is aiming to understand the brain mechanism that promotes the itch-scratching cycle.

“我们的研究旨在了解启动‘瘙痒-抓挠’循环的大脑机制。”

Some approaches focus on the neuroscience of hitting—the deep internal brain mechanisms behind seeing the pitch and reacting to it.

而一些方法则将重点集中在击球的神经科学方面—棒球运动员在看到球投出后做出反应，这背后所蕴藏的是大脑的深层机制。

That's down to a very different set of brain mechanisms.

这取决于一套非常不同的大脑机制。

A hypothesis here is simple. Because water is so critical for life, brain mechanisms evolved that help us spot and recognize it.

这里的一个假设很简单，因为水对生命至关重要，大脑机制的进化帮助我们发现和识别它。

Eventually, scientists hope this technology will help us study some of the brain mechanisms behind animal behavior, like making decisions or social interactions.

最终，科学家们希望这项技术能帮助我们研究动物行为背后的一些大脑机制， 比如做出决定或社交互动。

I think we're going to end up, in the next few years, to understand all kinds of brain mechanisms that pull us to one person rather than another.

我认为这一定有生物学上的解释。我想几年之内，我们就可以理解大脑是如何让我们找到我们唯一爱的人。

That's down to a very different set of brain mechanisms. It's also important to understand that melatonin is not well regulated as a supplement in several countries.

这取决于一套非常不同的大脑机制。同样重要的是要了解褪黑激素在一些国家并没有作为补充剂得到很好的监管。

This supported the idea that modern humans evolved some special vocal anatomy that paved the way for language, rather than developing special brain mechanisms to coordinate already-advanced vocal tracts.

这支持了这样一种观点，即现代人类进化出一些为语言铺平道路的特殊发声解剖结构，而不是发展出特殊的大脑机制来协调已经先进的声道。
