每根视束都在外膝体(lateral geniculate nucleus,LGN)和传递神经元(relay cell)进行突触联系。传递神经元的轴突向外发出,形成视辐射(optic radiations),将信息传递到大脑皮层同侧枕叶。

电信号到达传递神经元的突触附近后,释放化学物质包。
At the side of a synapse that belongs to the transmitting neuron, an electrical signal arrives and releases packets of chemicals.
多巴胺属于大脑化学物质家族的一员,它们传递神经元之间的信号。
Dopamine is one of a family of brain chemicals that transmit signals between neurons.
它显然是通过抑制神经递质的释放来做到这一点的。神经递质是一种将神经冲动从一个神经元传递到另一个神经元的化学物质。
It apparently does this by inhibiting the release of neurotransmitters, chemicals that carry nerve impulses from one neuron to the next.
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
