But we now know that a key player is anandamide.

但我们现在知道一个关键角色是 anandamide。

An international group of neuroscientists found that social contact made the brains of mice produce more anandamide.

一个国际神经科学家小组发现，社交接触使老鼠的大脑产生更多的大麻素。

The researchers gave other running mice a drug that blocks anandamide from binding to receptors.

研究人员给其他正在奔跑的老鼠服用了一种药物，这种药物可以阻止 anandamide 与受体结合。

They also looked at mice that were missing a gene that codes for the enzyme that breaks down anandamide.

他们还观察了缺失编码分解 anandamide 酶的基因的小鼠。

The mouse brains were then removed and flash-frozen, so that they could be tested for anandamide.

然后将小鼠的大脑取出并快速冷冻， 以便对它们进行 anandamide 测试。

Although naturally these cannabonoids circulate at much lower quantities compared to the large influx imposed by smoking, specifically the chemical tetrahydrocannabinol or THC resembles a natural transmitter called " anandamide" .

尽管与吸烟造成的大量涌入相比，这些大麻素的自然循环量要低得多，但特别是化学四氢大麻酚或 THC 类似于一种称为“anandamide”的天然递质。
