The healthy hair cell divides frequently.

健康的毛发细分裂频繁。

This can revive the dead hair cells and bring back your ear health.

这样可以死亡的毛细复，朵恢复健康。

The nerve that carries the sound from the hair cell to the brain.

神经会将声音经由绒毛细传输到大脑。

Each of these hair cells is attached to axons in the nervous system.

每毛细都附着在神经系统的轴突上。

It all has to do with these tiny hair cells in our ears.

这切都与我们朵里的这些微小的毛细有关。

And the way this is done is that there are so called hair cells...

转化通过所谓的毛细来实现。

The internal ear has tiny hair cells that help sweep the sound waves ahead.

内有微小的毛细，可以帮助将声波扫向前方。

This set-up also uses a combination of fluid and sensory hair cells.

这种设置也用了液体和感觉毛细的组。

Let's look at a healthy liver cell, a healthy hair cell, and a cancerous cell.

让我们分别看看健康的肝细，健康的毛发细，和癌变细。

This drug works at the junction — or synapse — between the hair cells and nerve cells.

这种药物作用于毛细和神经细之间的连接处或突触。

So noise canceling actually does remove the sound, leaving our ears hair cells, largely unaffected.

所以降噪实际上确实去除了声音，基本上不影响我们的毛细。

So when your hair cells are healthy, they stand up kind of like a field of wheat.

所以，当你的毛细健康时，它们就像片麦田样竖立着。

So you can damage the sensory hair cells in the inner ear or you can damage the nerves.

所以你会破坏内的感知绒毛细，你也可能会破坏神经。

Loud sounds can damage these hair cells in a way that can cause temporary, even permanent hearing loss.

巨大的声音会损坏这些毛细，从而导致暂时性，甚至是永久性听力损失。

And these emissions constitute a really strong demonstration of just how active the hair cell can be.

这些被释放的声音非常有力地展示了毛细有多跃。

And our group and many other groups are now engaged in research trying to resurrect these amazing hair cells.

目前，我们的团队和许多其他团队都致力于研究如何让这些美妙的毛细复。

This is exactly what hair cells do.

毛细的作用正是这样。

The first is: What is the molecular motor that's responsible for the hair cell's amplification?

负责毛细扩音作用的分子马达是什么？

Unlike mammalian hair cells, bird hair cells regenerate gradually after trauma.

与哺乳动物毛细不同，鸟类毛细在外伤后会逐渐再生。

The second issue is how the hair cell's amplification is adjusted to deal with the acoustic circumstances.

第二课题是，毛细的扩音作用是如何调节并匹配周围的声学环境的。
