In certain pseudounipolar neurons, the electrical impulse travels along an axon from the periphery to the cell body.

在某些假单极神经元中，电脉冲沿轴突从外周传递到胞体。

Instead, the team added body components that double as capacitors, devices that hold an electrical charge until they are tapped.

研究团队增加了体组件，比如双倍的电容器（这是一种能在换极前一直充电的元件）。

If these electrical signals could be detected and interpreted, the argument goes, there is in principle no reason why they could not be used to steer objects other than the thinker's own body.

如果我们能检测到并解释出这些电信号，这个论点就证毕了。理论上没有理由认为他们只能操纵思考者身体而不能操作其他物体。

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

Rather than by forming an image or a picture you put electrodes on the surface of the body and measure the electrical potential as a function of position on the body.

它并不对人进行直接的造影,而是将电极放到身体表面,通过测量该位置电势能,表征该部位的生理状态

As time goes on, we've developed ever more complex machines to study people and we've talked about some of these already: EKG machines, so an example of an electrical device that can be used to monitor a very elaborate function deep inside your body, the beating of your heart and the rhythm of your heart.

如今,我们已经有功能更加复杂的设备,来研究人类,比如之前说到的心电图,我们使用电子装置,对身体内部机能进行精确地监控,具体到心电图就是心跳和心率

Applying an electric current and getting a muscle to jump is easy. (Alessandro Volta jolted a frog's legs 218 years ago.) Peckham is harvesting the body's own electrical signals to control muscles that have been cut off from the nervous system, a process called functional electrical stimulation, or FES. Peckham runs a group called the Cleveland FES Center, a collaboration among Case Western Reserve and two Cleveland hospitals.

What you need is the scale that not only weighs you, it uses bio-electrical impedance to measure your body fat.

You see, each person's body provides a different amount of opposition to electrical current, so bioimpedance can be a unique biometric identifier.
