So I'm banging out my story and I know it's good, and then I start to make it —
我大声说出我的故事，我知道很好笑，为了让故事…
Suddenly, you can see that the responses in all of the subjects lock to the story,
突然间，所有人的脑波响应都随着故事的进展
and now they are going up and down in a very similar way across all listeners.
而上上下下，波型都很类似。
And in fact, this is exactly what is happening now in your brains when you listen to my sound speaking.
事实上，各位听我讲话的时候，这种现象也正在你的大脑里发生；
We call this effect "neural entrainment."
我们把这种现象称为神经震荡同步化效应。
And to explain to you what is neural entrainment, let me first explain what is physical entrainment.
为了要解释什么是神经震荡同步化，让我先解释什么是物理震荡同步化。
So, we'll look and see five metronomes. Think of these five metronomes as five brains.
我们来看看这五个节拍器，把这五个节拍器想象成五个大脑。
And similar to the listeners before the story starts, these metronomes are going to click, but they're going to click out of phase.
如同故事开始前的五位听者一样，这五个节拍器会开始打拍子，但并不同步。
Now see what will happen when I connect them together by placing them on these two cylinders.
现在来看一下，当我把它们放在这两个圆筒上，会发生什么事，
Now these two cylinders start to rotate.
两个圆筒开始滚动了。
This rotation vibration is going through the wood and is going to couple all the metronomes together. And now listen to the click.
圆筒滚动的振动，透过木板，把所有节拍器同步在一起，听听看现在的滴答声。
This is what you call physical entrainment.
这就是物理震荡同步化。
Now let's go back to the brain and ask: What's driving this neural entrainment?
现在让我们回到大脑，问一个问题：是什么在驱动神经震荡同步化呢？
Is it simply the sounds that the speaker is producing?
是讲者发出的声音？
Or maybe it's the words. Or maybe it's the meaning that the speaker is trying to convey.
还是所说的字汇？还是讲者想要表达的意思呢？
演讲者乌里.哈森通过观察人的大脑在听到声音时不同的变化做出研究，得出在不同的语言背景下大脑接收相同意思的信息呈现相似的现象。同时，说话者与聆听者在共同点的驱动下，大脑活动也会出现相似的情况。最后演讲者鼓励观众保持与人联系，从中找到我们是谁的定义。
