Because there are ions moving back and forth, there's a current that flows and there's a electrical potential that's generated.

由于离子的进进出出,就产生了电流流动,并且形成了电势差

The flow of information is really a flow of electrical potential and it goes in one direction only.

信息流实际上就是电势差的流动,并且流动是单向性的

It turns out the electrical potential or electricity that you can measure on the surface of the body reflects things that are happening deeper inside like the beating of your heart.

人们已经证明在体表测量得到的电势能,或者电信号,能够表征,像心跳这样,身体较深处的变化

By doing some of the heavy logical lifting for you, littleBits hopes that potential electrical engineers and prototypers can focus on the goal rather than the minutia of laying out a breadboard or soldering resistors in place.

But nothing actually travels the axon's length except a wave of electrical potential.
