Explained: why you forget things when walking into a room

A brain phenomenon known as "event boundary" is thought to be responsible for the memory lapse. Brains compartmentalize events and associate them with the environment in which they occured. When moving from one room to another, the brain essentially files away the thoughts generated in that room.
