Scientists make tests on mouses and then check conclusions on people. To remember the place we use "location neurones" and "boundary neurones". Using this neurones we can measure distance from different walls or things. To return to place we use "grid neurones" they help us makes path to the remembered object.

The conclusion from the video - scientists just start to study human brain using modern technologies for instance MRI devices. And we will discover a lot of interesting things about how the human brain works in nearest future!
