A Lesson in Sleep Learning

Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience online has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone – even when no odor is present – both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior.
