Although a little lidocaine would be nice.

过来点利多卡倒是。

It isn't a better numbing agent, but it does bind a different family of proteins better than lidocaine does: taste receptors.

它是一种更有效的麻醉剂，但它确实含有一组同但比利多卡更好的蛋白家族：味觉感受器。

Since lidocaine is incredibly useful, the drug researchers were trying to see if they could find something similar that worked even better.

既然利多卡超级有用，药品研究人员就想试一试能否找到比它更有效的类似物质。

They're telling us that drugs like lidocaine can help potential patients with breast cancer, things that, you know, our brains would have never just, you know, gone to immediately.

他们告诉我们，像利多卡这样的药物可以帮助潜在的患者，这些信息，你知道，我们的大脑可能永远会立即想到。

Medications like lidocaine or Xylocaine, which you typically get at the dentist or for some minor procedures, basically block the opening of voltage-gated sodium ions, which means that you can't really have those action potentials spread.

像利多卡或昔洛卡这样的药物，通常会在牙医那里或一些小手术中使用到，基本上阻止了电压门控钠离子的开放，这意味着你无法让动作电位扩散。
