People who want to learn things might do better by simply stopping to smell the roses, researchers reported on Thursday. German researchers found they could use odors to re-activate new memories in the brains of people while they slept and the volunteers remembered better later.

Writing in the journal Science, they said their study showed that memories are indeed consolidated during sleep, and show that smells and perhaps other stimuli call reinforce brain learning pathways.

Jan Born of the University of Lubeck in Germany and colleagues had 74 volunteers learn to play games similar to the game of “Concentration” in which they must find matched pairs of objects or cards by turning only one over at a time.

While doing this task, some of the volunteers inhaled the scent of roses. The volunteers then agreed to sleep inside all MRI tube. Functional magnetic resonance imaging was used to "watch" their brains while they slept. At various stages during sleep, Born’ s team wafted in the same scent of roses.

The volunteers were tested again the next day on what they had learned. “After the odor night participants remembered 97. 2 percent of the card pairs they had learned before sleep, ” the researchers wrote. But they only remembered 86 percent of the pairs if they did not get the rose smell while sleeping.
