"Their findings show that memory is divided into discrete individual packets, analogous to the way that light is divvied up into individual bits called quanta. Each memory is just 125 milliseconds long -- which means the brain can swap between different memories as often as eight times in one second. "The brain won't let itself get confused," says Professor May-Britt Moser. "It never mixes different places and memories together, even though you might perceive it that way. This is because the processes taking place inside your head when your brain is looking for a map of where you are take place so fast that you don't notice that you are actually switching between different maps. When you feel a little confused, it is because there is a competition in your brain between two memories. Or maybe more than two.""
