the truth of the matter is, we don’t really know for sure! We know that there is a region in your brain called the hippocampus (it’s right in the centre of your head, and looks like two bananas stuck together). In people where this part of the brain is damaged, no new memories are formed so we think that this regions is important. People often ask me where the information is stored – again that is an unknown at the moment. What we think happens is that the electrical impulses generated by the hippocampus when it is stimulated by your learning at school affect other brain cells nearby, something we call ‘synapse strengthening’, this may be the cause of memory. But re-iterate, at the moment we don’t really know.
