That would be - you could have a cell that did that but that would be cell that could only send one signal.

那样就会,你的细胞可以发出信号,但这个细胞只能发出一次信号

This same thing happens here, there's a transduction, one kind of a signal gets converted to another kind of a signal.

这两种过程是相同的,都是一个信号转换的过程,一种信号转化为另一种信号

Each one of those electrodes allows us to measure, we plot voltage verses time, ? this signal coming from the tip of that electrode. Ok?

我们通过每个这样的电极都可以设计一种测量方法，我们设计电压比时间，这一信号源于电极的一端，对吧？

Well, one reason to do this is because on each post-synaptic neuron there might be many axons coming together at once, and each one might be generating a different kind of signal, through maybe even different neurotransmitters.

嗯 一个原因是在每个,突触后神经元上可能有,许多同时到达的轴突,每个都可能通过不同的神经递质,产生不同的信号

This is a mechanism by which an electrical signal comes here, it gets translated into a chemical signal, the chemical diffuses across the gap and reinitiates a - an electrical signal in the next cell and that's one way that it happens.

这就是电信号产生的机理,电信号翻译成化学信号,化学物质扩散过突触间隙,重新激起下个细胞中的电信号,这是一种方式
