For example, the feeling of runner's high comes from the natural neurotransmitter endorphin activating your opioid receptors.

例如，跑步者高潮就是来自天然神经递质内啡脑，激活了阿片受体。

Whenever you hug someone, your touch activates special pressure receptors in their skin.

每当你拥抱某人时，你的触摸都会激活他们皮肤中的特殊压力感受器。

When we take a bite of food, certain molecules activate receptors spread all over our tongue.

当我们咬食物时，某些分子会激活遍布整个舌头的受体。

The sugars it contains activate the sweet taste receptors, part of the taste buds on the tongue.

它所含的糖触发甜味受器，那是舌头上味蕾的一部份。

Semaglutide is a type of GLP-1 agonist, which means that it binds to and activates specific receptors in the body.

Semagrutide是一种GLP-1促效药，它能与体内的特定受体结合并激活。

Opioids work by binding to and activating the opioid receptors located throughout the body, blocking pain signals.

阿片类药物通过结合并激活遍布全身的阿片受体来发挥作用，阻断疼痛信号。

That means it activates the cannabinoid receptors in your brain.

这意味着它会激活大脑中的大麻素受体。

If you produce something that activates those receptors it could potentially be sedating.

如果你生产的东西可以激活这些受体，它可能会起到镇静作用。

Cyclic AMP (cAMP) is produced when the receptor protein activates another membrane-bound protein called a G protein.

当受体蛋白激活另一种称为G蛋白的膜结合蛋白时，就会产生环磷酸腺苷 (cAMP)。

It also activates noradrenaline receptors, which increases the heart rate, dilates pupils, and triggers the body's fight or flight response.

它还会激活去甲肾上腺素受体，从而增加心率、放大瞳孔并触发身体的战斗或逃跑反应。

That’s likely because they activate receptors in a broad range of brain areas, including the cortical regions for all the senses.

这可能是因为它们激活了广泛大脑区域的受体，包括所有感官的皮质区域。

That happens because spices trigger the same neural response in the brain that activates temperature receptors, which usually respond to increased heat.

发生这种情况是因为香料在大脑中触发了与激活温度感受器相同的神经反应，而温度感受器通常会对增加的热量做出反应。

So, even though the pituitary dials down its hormone production, in an effort to get the thyroid to stop, the thyroid does not get the message, because the receptors are still being activated.

所以，即使脑垂体降低了激素的分泌，试图让甲状腺停止，甲状腺也没有收到信息，因为受体仍然被激活。

A lot of people use hydrogen peroxide to clean wounds, and it isn't exactly pleasant: in addition to making the scrape hurt even more by activating the receptors that make you feel pain, the wound gets all weird and bubbly.

许多人用过氧化氢清洗伤口，而这并不令人十分愉快：除了会激活让你具有痛感的感受器，让伤口更痛以外，创伤处会变得更可怕，还会起泡。

Now, as I mentioned at the beginning of this lecture, in Parkinson's disease, dopamine depletion leads to increased acetylcholine release, which then activates muscarinic receptors located on the neurons responsible for smooth motor control.

现在，正如我在这堂课开始时提到的，在帕金森氏症中，多巴胺耗尽导致乙酰胆碱释放增加，然后激活毒蕈碱受体位于负责平稳运动控制的神经元上。

A lot of people use hydrogen peroxide to clean wounds, and it isn’t exactly pleasant: in addition to making the scrape hurt even more by activating the receptors that make you feel pain, the wound gets all weird and bubbly.

很多人使用过氧化氢来清洁伤口，这并不是一件令人愉快的事情：除了通过激活让你感到疼痛的感受器而使擦伤更加疼痛之外， 伤口会变得很奇怪并且起泡。
