How sound can hack your memory while you sleep

Can you cram for a test while you sleep? Our intrepid neuroscientists attempt to enhance memory by running experiments on subjects while they sleep. You'll be surprised by the results.

Research reveals that memories can be reinforced during the deepest stage of sleep by pairing learned information with specific sounds. In experiments, playing associated sounds to sleeping participants helped them better recall information, like the location of images in a memory game. Even without conscious awareness, the reactivation of memories through sound made them less likely to fade. This suggests the brain works behind the scenes to stabilize knowledge while resting.
