 For science communication it's about, ultimately it's about democracy, because I think democracy relies on an informed public. So the people who go to elections should have a general knowledge, not only about science, about anything, about how the society works and about why things are like they are. In that sense people need to know how knowledge is generated, they need to know the process of actually obtaining knowledge and when you can trust knowledge and when you can't. We have discovered that there are various types of cells in this part of the brain that tells the rest of the brain our location in space. So one of them is the grid cells, grid cells are like an internal coordinate system in the brain, it has often been compared to an internal GPS, because these cells keep track of our locomotion, how far we move, what distance and direction we move and then infer from that where we are, just like a GPS when we drive a car. Well at two levels, so first of all it helps us to understand space, how we actually know where we are and how we can get from one place to another. But at another level it also is one of the first higher brain functions or cognitive functions that they're beginning to understand the neural mechanisms of.
