The question of how our memory works has kept scientists busy for decades. How do we learn German words or the capitals cities of Europe? What happens in our brain when new information enters? Where does this information end up and how is it stored? Beyond fundamental questions there are numerous hereditary diseases in which the brain has lost its ability to store information. How is that possible? Will there be a memory-pill in the future for patients that suffer in this way? Patient studies and animal research have helped us learn about the way our brains learn, an area of significant medical interest.
