Once upon a time catching a glimpse of a mouse's brain used to be a ton of work considering how energetic they are. They either had to be held down in place or be trained to walk on a moving platform (not really sure how that helps scientists see into their brains, but hey if it works then it works). But now using this mini microscope (which weighs less than 2 grams) allows scientists to constantly observe mice brains all day long and they are small and light enough that they really dont inhibit the mice in any fashion and they act totally normal, even if it is a funny looking hat.
