Consider that the human brain alone has 100 billion neurons, and each of those has 1000 to 10,000 synapses.

考虑人类大脑本身就有 1000 亿神经元，每个神经元都有 1000 10000 个突触。

Filopodia did not, confirming the silence of their synapses.

而树突丝突触没有反应，证明它们突触是沉默突触。

In both systems, neurons release acetylcholine, or ACh, in their preganglionic synapses.

在这两个系统中，神经元在节前突触中释放乙酰胆碱。

There are hundreds, possibly thousands of different kinds of connections, or synapses.

有成百上千种不同类型连接，或突触。

This information is saved by altering neurons and creating synapses and connections.

这样讯息能因神经元不断改变及神经键和连结创造而被储存下来。

The human brain has 100 billion neurons and up to 150 trillion synapses.

人脑含有1000亿个神经元和多达150兆神经键。

SSRIs reduce the reuptake of serotonin, which increases the amount of serotonin hanging around synapses.

SSRIs 减少了 5-羟色胺再摄取，从而增加了突触周围 5-羟色胺含量。

The metaphor of the brain is tempting, but " neurons" and " synapses" deserve those scare-quotes.

大脑这个比喻听起来很诱人，但是“神经元”和“突触”值得我们引用一下。

" And they will form connections, and these connections will form functional synapses that will, later on, turn into networks."

“它们会形成连接，这些连接会形成功能性突触，突触随后会联成网络。”

They studied 2,234 synapses between cortical nerve cells of a type called pyramidal neurons, which have thousands of synapses each.
