We've then talked about how neurons can communicate to one another; then, turned to how neurons are wired up together.
接着我们还讲了,神经元之间是如何进行信息传递的,之后,我们又谈到了,神经元是如何连结在一起的
Now because it is so important to understand how the neurons present the information, ? let me go into a bit more detail. Ok?
既然要理解,神经元传递信息是如此重要,我来更加详细地解释一下,好吧?
Many neurotransmitters that carry signals between neurons in your brain work this way.
在脑部神经元细胞中,传递信号的神经递质分子的,作用原理就是如此
And then if you get a certain number, plus 60 or something, the neuron will fire and it fires along the axon, the thing to the right.
如果达到了一定的数量,比如超过60之类的,神经元便会产生神经冲动,神经冲动沿轴突传递,右边的是轴突
There are sensory neurons, which take information from the world so as you see me, for instance, there are neurons firing from your retina sending signals to your brain.
感觉神经元,负责收集外界信息,比如,当你看到我的时候,视网膜上的神经元会产生神经冲动,将刺激信号传递到你的大脑
So, neurons communicate to one another chemically.
这样,神经元之间便通过化学方式,进行信息的传递
One is that there's a physical space in between the two cells, so the axon of what's called the pre-synaptic neuron, or the neuron that's bringing a signal into the synapse, the axon terminal is physically separated from the dendrite of the next cell.
一是两个细胞间有一定的物理空间,所谓的突触前神经元,也就是将信号传递到突触的神经元的,轴突的末梢,同下一个细胞的树突间被物理性分离开
