In contrast, chemical synapses are capable of more variable signaling and thus can produce more complex behaviors.
相反，化学突触具有制造出多变信号的能力，因此，它能制造出很多复杂的信号。
But how various types of spike trains are transmitted across chemical synapses between neurons is still an open question.
但是各种脉冲序列如何通过神经元之间的化学突触进行传递依然是一个悬而未决的问题。
Electric synapses are found mainly in invertebrates and lower vertebrates; they transmit messages faster than chemical synapses.
生物电性突触多见于无脊椎动物或低等脊椎动物，其传递讯息快于化学性突触。
Burst synchronization and burst dynamics of a system consisting of two map-based neurons coupled through chemical synapses were studied.
本文研究了经化学突触耦合的两个神经元的簇放电同步以及耦合后神经元的簇放电动力学性质。
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.
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。
Besides the synapses that mediate electrical signals, there are also so-called gap junctions that allow direct chemical communication between neurons.
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。
The key, he says, is not the neurons but the synapses, the electrical-chemical-electrical connections between those 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。
That night, the scientists injected a chemical into the brains of some of the mice. The chemical had been shown to block neurons in dishes from pruning their synapses.
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。
