对老鼠的个别海马体神经元的多次研究显示出其一特性：他们拥有能够找到某些地方的惊人能力--释放位置细胞脉冲。

A much-studied property of individual hippocampal neurons in rats is their striking ability to hone activity to certain places – known as place-cell firing.

位置细胞是如此的逼近实际的轨迹，以至于研究者可以通过监视在特定时间上哪些位置细胞被激活，就能获知老鼠沿着轨迹跑动的进度。

Place cells correspond so closely to exact physical locations that the researchers could monitor the rats’ progress around the track simply by watching which place cells were firing at any given time.

种群中的每一个个体细胞都在内部存储了一个网格位置，所以，当我想要找到某个细胞的网格位置时，不必搜索网格或者维持一个外部散列表。

Every individual cell in the population has a grid position stored internally, so I don't have to search the grid or maintain an external hash when I want to find a cell's grid position.

It turns out that one of the places that's been very fruitful to look for proteins that differ between cell populations is on the surface of the cell.

而事实证明,寻找能鉴别细胞种类的,特定蛋白的最佳位置,是在富含蛋白的细胞膜上

What if we could just take a few cells from that donor organ, ship them to the site, grow a new organ at the site and then implant it there?

如果我们只需,从供体器官中取一些细胞,把他们放到适当的位置培养出新的器官,就完成了移植过程,这又意味着什么

Now I isolated these cells maybe from the head region of the embryo, the region that's going to develop into the brain, so that would be a good place to look if you wanted cells that were going to develop into the brain.

现在我可以从胚胎的头部,分离这些细胞,从就要发育成为大脑的这些部位,这是取得你需要的细胞的绝佳位置,如果你想要发育成大脑的细胞的话
