Another characteristic of the synapse is that the post-synaptic membrane, the membrane of the cell which is going to receive the signal has receptors on it.

突触的另一个特征是,它们都有一个突触后膜,这个膜上含有受体,可以接受信号

It won't be long before we're using these same kind of devices to both record--to test what's going on-- and to act in the right way and response.

相信不久以后,这个装置就可以同时记录和反馈,大脑的信号,并做出相应的回应

It could be the response is 'there's something dangerous in the environment, we got to move away', and so the response is for the cell to crawl in the opposite direction.

这个信号还有可能是,"外面很危险,我们得赶紧跑",于是细胞就向相反方向游走了

If you hear about signal transduction in biology, people that study signal transduction are studying just these things we talked about, how biochemical messages get transferred into cells and through cells.

如果你在生物学领域听到信号转导这个词,那么研究信号转导的人就是,在研究我刚才讲过的那些东西,生化信息如何传入细胞并传递至细胞各处

So, it makes a binary decision, either I create an action potential or I don't, but that decision could be based on many inputs, not just on input from one cell.

所以 这里产生一个二选一的决策,就是产生动作电位亦或不产生,不过这个决定可能是,根据很多输入信号做出的,而不是仅凭单个细胞所传来的信号

Here, what's different between autocrine and paracrine is that there's some distance between the cell that produces the signal and the cell that receives the signal, but it's not too great a distance because the blood system doesn't have to be involved.

自分泌和旁分泌的区别在于,旁分泌中,产生信号的细胞和接收信号的细胞,之间存在着一定的距离,但这个距离并不远,因为血液系统并不参与
