Getting to the bottom of memory

Phone numbers, the way to work, granny's birthday -- our brain with its finite number of nerve cells can store incredible amounts of information. At the bottom of memory lies a complex network of molecules. To understand how this network brings about one of the most remarkable capacities of our brain we need to identify its components and their interactions. Researchers from the European Molecul...
