Article and video clip about mouse and monkey brain cells injected with luminous molecules which shine through their skin, so scientists can study them easily in experiments. For example they put the mouse in a different place, and can see the effect on memory neurons in its brain, from outside it.

I am against animal experiments. This is horrible.
