Why do we remember some events, places and things, but not others? Our brains prioritize rewarding memories over others, and reinforce them by replaying them when we are at rest, according to new research from the University of California, Davis, Center for Neuroscience, published Feb. 11 in the journal Neuron.

“Rewards help you remember things, because you want future rewards,” said Professor Charan Ranganath, a UC Davis neuroscientist and senior author on the paper. “The brain prioritizes memories that are going to be useful for future decisions.”
