It’s the dream of any kid too lazy to study: put on a set of earphones when you go to bed and learn while you’re sleeping. The good news? According to a new study, this is absolutely a possibility. The bad news? It’s not quite as simple as that.
The research, published in the journal Nature, shows that new auditory memories can be formed as we sleep, although these are only laid down during particular phases of our slumber. In an experiment, sleeping subjects were exposed to white noise incorporating a recurring tonal pattern. Using electroencephalographic (EEG) and behavioral response analysis, the researchers demonstrated that subjects learned the sound patterns during cycles of REM sleep. This refers to the sleep phases characterized by rapid eye movements, which involve more dreaming, body movement, and faster breathing. Some learning also takes place during the N2 sleep phase, referring to the first unequivocal stage of sleep, during which muscle activity decreases, as does awareness of the outside world.
