When we measure EKG's, what we're measuring is the activity of all these cells within our heart performing action potentials.

当我们做心电图的时候,我们所测量的是心脏内能发出,动作电位的细胞的活动状态

In the brain, action potentials are moving down processes, down a single cell process for example.

在大脑中 动作电位沿突起传递,比如说沿着一条单独的细胞突起吧

What we are hearing were periods of quietness and periods of a lot of action potentials.

我们听到的是一段寂静,然后是可能出现很多活动的一段时间。

We'll come back to this in our example in the cardiovascular system when we're talking about the heart and we'll talk about how to measure the collective group of action potentials using EKG's.

这个我们回头再谈,等到我们在心血管系统的例子中,说到心脏时再说,我们会谈到如何通过,心电图测量群体动作电位

Now what we do is to record the number of those action potentials in some period of time, and plot them on the graph below.

现在，我们要做的是记录,在一定时间内可能做出的动作，在图表中设计出来。

We're going to come back and talk about the action potential a little bit more when we talk about how the heart works, because the heart when its contracting, the muscle cells also use action potentials to initiate contraction.

我们讲心脏工作原理时,会回头再多讨论一点动作电位,因为心脏收缩时,肌肉细胞也利用动作电位来启动收缩
