How memories form and how we lose them?

我们的记忆是如何形成，又是如何消失的？

Think back to a really vivid memory. Got it? Okay, now try to remember what you had for lunch three weeks ago. That second memory probably isn't as strong, but why not? Why do we remember some things, and not others? And why do memories eventually fade?

回想一个生动的回忆，好了吗？好的，现在，想想三周前你午餐吃了什么？这个回忆可能就不是那么栩栩如生了吧，为什么会这样呢？为什么我们会记住一些事情，而忘却另外一些事情？为什么记忆最终会一点一点褪色？

Let's look at how memories form in the first place. When you experience something, like dialinga phone number, the experience is convertedinto a pulse of electrical energy that zips along a network of neurons.

让我们先来看一下，记忆是如何产生的。当你经历事情的时候，比如拨电话号码，这个体验会被转化成一种脑电波脉冲，这种脉冲快速地沿着神经网络前进。

Information first lands inshorttermmemory, where it's available from anywhere from a few seconds to a couple of minutes. It's then transferredto long-term memory through areas such as the hippocampus, and finally to several storageregions across the brain.

信息首先到达短期记忆处理中心，这是一个存储几秒钟到几分钟记忆的区域。然后，信息通过海马体等区域被转成长期记忆，最终保存到大脑几个记忆储存区域。
