化学突触也经常用来放大神经信号，即便是一个很小的突触后细胞也能改变一个很大的突触后细胞对信号的响应。
Chemical synapses also serve to amplify neuronal signals, so that even a small presynaptic nerve terminal can alter the response of a large postsynaptic cell.
除了形成电子信号的突触以外，还有使得神经元之间产生直接化学通信的缝隙连接。
Besides the synapses that mediate electrical signals, there are also so-called gap junctions that allow direct chemical communication between neurons.
他表示，关键在于突触，而不是神经元，神经元之间是通过电学-化学-电学的连锁反应进行联系。
The key, he says, is not the neurons but the synapses, the electrical-chemical-electrical connections between those neurons.
这些基因在大脑中活动在创造，巩固和修改突触路径上——当我们学习新东西时，发生在物理和生物化学上的改变。
These genes are active in creating, reinforcing or modifying synaptic pathways in the brain — physical and biochemical changes that occur when we learn something new.

从神经学的角度来说，一个想法只是一种分泌物，是位于两个大脑细胞连接处(突触)的化学物质中的一小滴。
From a neuroscience viewpoint, a thought is just a secretion, a droplet of a chemical where two brain cells connect (synapse).
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.
当天晚上，科学家将一种化学物质注入若干小鼠的脑中。在实验室中，这种化学物质已被证明可以阻止神经元减少其突触。
