There are some really interesting research projects coming out of the neuroscience lab at Northwestern University. A couple
months years ago, I wrote a blog post about a
study that shows we continue to learn after a study session if the stimulus continues while we’re doing something else. Pretty cool, right? But maybe you prefer to catch up on your sleep and continue learning.
Now there is evidence that we continue to learn when we sleep. In this study by researchers at Northwestern (Antony, J.W., Gobel, E.W., O’Hare, J.K., Reber, P.J., & Paller, K.A.), apparently published June 26 in Nature Neuroscience. I can’t find it there, and according to NU’s neuroscience lab, it’s still “In Press,” meaning it hasn’t been published yet. It could be that the study wasn’t approved by the peer review process, so there may be problems with the study. Stay tuned.
Anyway, the participants in the study practiced a musical skill requiring precise timing, then took a 90 minute nap. During the nap the participants were wired with an EKG that monitored their brain waves and when the optimal time came, the researchers played soft musical cues, using the same music participants practiced earlier. Some got the soft musical cues, and the control group did not.
They woke the participants, tried the musical task again and were measured precisely. Those who got the musical cue while sleeping did significantly better than those who didn’t get it. Sweet!
Sleep is important to cognitive function, a subject I’ve written about before, naps specificially. Make sure you get your 40 winks at night, and if you can, snatch a nap here and there, too, especially after a long or difficult practice session.
