So how do you find an engram?

那怎么找到忆迹？

Now the next question was whether altering the neurons in the engram would mess with the memory.

下一个问题改变忆迹中神经元，否会扰乱忆。

That's how corruptive pain is to the neurological engram.

这就疼痛对神经破坏性影响。

In particular, Lashley wanted to locate the memory trace, or engram, the specific place in the brain responsible for memory.

特别， 拉什利想要定位忆痕迹，或engram， 脑中负责忆特定位置。

But, if manipulating engram cells can add, delete, and modify memories in predictable ways, that does mean engrams are a useful model for studying memory.

但，如果操纵忆迹细胞能以可预测方式增加、删除和修改忆，那就意味着忆迹研究忆有用模型。

The researchers taught a mouse to associate a sound with a shock and then pumped the engram cells, where they knew that memory lived, full of this light-sensitive protein.

研究人员教一只老鼠把声音和电击联系起来，然后给他们所知道忆存在部位注入忆迹细胞，细胞中充满这种感光蛋白。

The word scientists use to talk about this physical trace of a memory in a brain, the pattern of cells that activate to recall a memory, is an engram.

科学家用来谈论脑中忆物理痕迹，激活回忆忆细胞模式，一个忆迹。
