Better to target... use as much muscle as possible with every movement,
更好的目标是,尽量让更多的肌肉参与到每一个动作中。
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
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。
And I have here two ways you could learn from looking.
你可以通过两种方法,从注视这个动作中得出一些结论
In general, if you're watching an action movie and there's a car chase and the trucks and cars are crashing all over the place, and let's say a Budweiser truck shows up in the scene somehow, well people are very likely paying for that.
如果看一部动作电影中有汽车追踪,以及卡车和汽车到处碰撞的场景,就说在电影里出现的是百威的卡车,这家公司的人很有可能为这个场景花钱了
In the heart it turns out that the cells of the heart are electrically coupled together, so if an action potential moves down this cell it directly moves into the next cell.
在心脏中,事实证明,心脏细胞是电偶联的,所以如果动作电位在一个细胞中传递,那么直接就能传递给下个细胞
If you could look inside a pre-synaptic axon terminal, you would find one of the characteristics is that it's loaded with these vesicles and they're just sitting there waiting to receive an action potential so that they can immediately dump their contents.
如果你能够一窥突触前的轴突末梢内部,你将会发现一个共同特征,神经递质都装载在小泡中,时刻准备着等待动作电位激活,以便迅速释放其内含物
