XL: When you zoom in into the hippocampus, of course you will see lots of cells, but we are able to find which cells are involved in a particular memory, because whenever a cell is active, like when it's forming a memory, it will also leave a footprint that will later allow us to know these cells are recently active.
XL: Når man zoomer ind i hippocampus, vil man selvfølgelig se mange celler, men vi er i stand til at finde ud af hvilke celler der er involveret i et bestemt minde, fordi når en celle er aktiv, som når den former et minde, vil den også efterlade et fodaftryk der senere vil tillade os at vide at disse celler var aktive for nyligt.
