Maybe you should take a nap with the same melody playing during your sleep, new provocative Northwestern University research suggests.<\/p>\n<p>The research grows out of exciting existing evidence that suggests that <strong>memories can be reactivated during sleep<\/strong> and <strong>storage of them can be strengthened in the process<\/strong>.<\/p>\n<p>In the Northwestern study, research participants learned how to play two artificially generated musical tunes with well-timed key presses. Then while the participants took a 90-minute nap, the researchers presented one of the tunes that had been practiced, but not the other.<\/p>\n<p>&#8220;Our results extend prior research by showing that <strong>external stimulation during sleep can influence a complex skill<\/strong>,&#8221; said Ken A. Paller, professor of psychology in the Weinberg College of Arts and Sciences at Northwestern and senior author of the study.<\/p>\n<p>By using EEG methods to record the brain&#8217;s electrical activity, the researchers ensured that the soft musical &#8220;cues&#8221; were presented during <strong>slow-wave sleep, a stage of sleep previously linked to cementing memories<\/strong>. Participants made fewer errors when pressing the keys to produce the melody that had been presented while they slept, compared to the melody not presented.<\/p>\n<p>&#8220;We also found that electrophysiological signals during sleep correlated with the extent to which memory improved,&#8221; said lead author James Antony of the Interdepartmental Neuroscience Program at Northwestern. &#8220;These signals may thus be measuring the brain events that produce memory improvement during sleep.&#8221;<\/p>\n<p>The age-old myth that you can learn a foreign language while you sleep is sure to come to mind, said Paul J. Reber, associate professor of psychology at Northwestern and a co-author of the study.<\/p>\n<p>&#8220;The critical difference is that our research shows that <strong>memory is strengthened for something you&#8217;ve already learned<\/strong>,&#8221; Reber said. &#8220;Rather than learning something new in your sleep, we&#8217;re talking about <strong>enhancing an existing memory by re-activating information recently acquired<\/strong>.&#8221;<\/p>\n<p>The researchers, he said, are now thinking about how their findings could apply to many other types of learning.<\/p>\n<p>&#8220;If you were learning how to speak in a foreign language during the day, for example, and then tried to reactivate those memories during sleep, perhaps you might enhance your learning.&#8221;<\/p>\n<p>Paller said he hopes the study will help them learn more about the basic brain mechanisms that transpire during sleep to help preserve memory storage.<\/p>\n<p>&#8220;These same mechanisms may not only allow an abundance of memories to be maintained throughout a lifetime, but they may also allow memory storage to be enriched through the generation of novel connections among memories,&#8221; he said.<\/p>\n<p>The study opens the door for future studies of sleep-based memory processing for many different types of motor skills, habits and behavioral dispositions, Paller said.<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Northwestern University press release: Want to nail that tune that you&#8217;ve practiced and practiced?
