retina

Consider one of the difficulties: every time we move our eyes, the image on our retina moves.

比如困难之一就是：每当我们的眼球移动时，视网膜上的影像也在移动。

There are sensory neurons, which take information from the world so as you see me, for instance, there are neurons firing from your retina sending signals to your brain.

感觉神经元,负责收集外界信息,比如,当你看到我的时候,视网膜上的神经元会产生神经冲动,将刺激信号传递到你的大脑

A tiny electronic pad is placed onto the retina of one eye, so that the electrodes are in direct contact with the ganglion cells.

一个微小的电子衬垫被放置在单侧眼睛的视网膜上，这样电极就可以与神经节细胞直接接触了。
