So on top of L-Dopa, they gave these kids a serotonin precursor drug, and they're effectively normal now.

所以除了L－多巴，他们也用血清素前体药物辅以治疗，孩子们恢复正常了。

And what they found was a series of mutations in a gene called SPR, which is responsible for producing serotonin, among other things.

他们发现了SPR基因上的一个系列突变，这个片段与产生血清素的功能相关。

When Leonard gets back, I'd love to check his serotonin levels. Do you think he'd let me draw a syringe full of his blood?

等莱纳德回来的时候，我想检测一下他体内的血清素水平，你觉得他会让我抽他一管血吗？

But because MDMA releases so much serotonin, your body also destroys more than usual.

但因为摇头丸释放太多复合胺了，你身体消灭的复合胺也比正常时多。

I read a study online that walking after a meal not only aids in digestion, but increases serotonin, and you know me, if there's one thing I like more than a refreshing beverage, it's serotonin. Bye bye.

我在网上看过一篇论文，饭后百步走不仅有助于消化，还能增加5 羟色胺的含量，而且你们也知道的，如果说相比提神饮料我更喜欢什么，那肯定就是5 羟色胺了，拜拜。

They lose their sensitivity to serotonin and norepinephrine. Which leads to? Impaired cognitive function.

会失去对5 羟色胺和正肾上腺素的敏感性。那就会引起？认知功能受损。

In particular, the neurotransmitter called serotonin controls appetite, sleep, memory, learning and in this case, mood.

特别的是，复合胺，神经传递介质一种，控制了食欲、睡眠、记忆、学习，这情况下，还改变了情绪。

These feelings generally lasts around 3-8 hours, as your brain cells naturally work to reuptake the serotonin and have it chemically destroyed.

这种感觉可以持续三到八个小时，脑内细胞会想摄取更多复合胺，然后用化学方法摧毁它。

This means when your brain function is back in its' normal state, there is less serotonin available to bind to your receptors and make you feel good with normal events.

也就是说，当你的脑功能恢复正常运作，身体里的复合胺太少，抑制了你的感官，所以对普通的事都感到美好。

《TOFEL（无字幕版）》《托福学习视频》

When something really great happens in your life, say you fall in love, there is an increase in the release of serotonin from nerve cells, which ultimately stimulates your body and makes you feel happy.

比方说生命中某件大事发生了，例如谈恋爱神经细胞中的复合胺就会增加，进而刺激你的身体，让你感到快乐。

These same cells are triggered to release enormous amounts of serotonin, along with other neurotransmitters like dopamine and norepinephrine, which trigger even more electrochemical firing in the brain.

释放出大量的复合胺，还有其他的神经传递介质，例如多巴胺跟正肾上腺素这更引起了脑中更大的化学反应。

However, this treatment remains fairly controversial as studies on rats and monkeys have shown that even small amounts of MDMA can not only destroy the endings of brain cells involved in the release of serotonin but potentially cause permanent brain damage.

然而，这种疗法现在还很有争议，因为对老鼠和猴子进行药物测试发现，摇头丸不只会破坏那些制造复合胺的脑细胞，还极有可能造成大脑永久损坏。
