The drug blocked the function of the nerve receptors lacking GluA2.

这种药物阻断了缺乏 GluA2 的神经受体的功能。

First, the high concentration of capsaicin, the chemical that causes spiciness in peppers, binds to a nerve receptor in your mouth.

首先，该辣椒中高浓度的辣椒素 （就是这类化学物质使辣椒产生辣味）会与你嘴里的特定神经受体结合。

And here, special nerve receptors measure pressure, and when enough waste pushes against the rectum walls, it triggers the defecation reflex.

这里，特殊的神经感受器测量压力，当足够多的废物冲击直肠壁时，它会触发排便反射。

Adrenaline can bind to nerve receptors connected to the iris dilator, making it contract and pull your pupils open wide.

肾上腺素可以与连接到虹膜扩张器的神经受体结合，使其收缩并拉大你的瞳孔。

Here, special nerve receptors measure pressure, and when enough waste pushes against the rectum walls, it triggers the defecation reflex.

在这里， 特殊的神经感受器测量压力，当足够多的废物推到直肠壁时，它会触发排便反射。

The peripheral nervous system's sensory nerve receptors spy on the world for the central nervous system, and each type responds to different kinds of stimuli.

周围神经系统的感觉神经受体为中枢神经系统窥探世界，每种类型对不同种类的刺激做出反应。

That's because some of the spiciest foods contain compounds that bind to nerve receptors along the gastrointestinal tract, including the mouth, that are activated by heat.

这是因为一些辛辣食物中含有能够与胃肠道以及口腔神经受体结合的化合物，这些受体会被热量激活。

And then we've got specialized nerve receptors called nociceptors that, unlike those other receptors, fire only to indicate pain, which is the main thing I want to talk about today.

然后我们有一种特殊的神经感受器，叫做伤害感受器，与其他感受器不同，它只发出信号来指示疼痛，这是我今天想谈的主要内容。
