This terminal holds a whole bunch of tiny synaptic vesicle sacs, each loaded with thousands of molecules of a given neurotransmitter.

这个终端包含一大堆微小的突触囊泡囊，每个囊泡囊都装载着数千个特定神经递质的分子。

This flow of positively-charged calcium ions causes all those tiny synaptic vesicles to fuse with the cell membrane and purge their chemical messengers.

这种带正电荷的钙离子流动导致所有这些微小的突触囊泡与细胞膜融合并清除它们的化学信使。

Normally, electrical signals, or action potentials, travel down the axon to the axon terminal, where they trigger the release of chemical messengers called neurotransmitters from synaptic vesicles into the synapse.

通常情况下，电信号或动作电位通过轴突传递到轴突末梢，从而刺激化学信号分子（神经递质）从突触小泡释放到突触间隙。

Dopamine is then loaded into synaptic vesicles and released by physiological stimuli into the extracellular space where it can bind to dopamine receptors that are expressed on the postsynaptic neuron.

多巴胺随后被装入突触囊泡，并通过生理刺激释放到大脑中与多巴胺受体结合的细胞外空间突触后神经元。

And once we saw that they were the same as a subset of the ones in the synapse, we can pinpoint them and say, well, that's how the synaptic vesicle works.

罗斯曼：一旦我们发现它们与突触中的一部分相同，我们就可以确定它们的位置，然后说，嗯，这就是突触小泡的工作原理。
