Memory processing during sleep encourages motor skill learning and neurorehabilitation

Researchers at Northwestern University, US, have found that additional memory processing during sleep fortifies learning and executing a new and challenging motor skill. The research provides insight into the relationship between slumber and brain function by demonstrating how sound cues played during deep or slow-wave sleep can supplement learning of motor skills.

A cohort of participants were tasked with playing a unique computer game, one that required them to move the cursor by activating specific arm muscles – participants played the computer game blindfolded, after learning sound cues which shifted the cursor in specific directions.

The researchers noticed the participants performed far better after a 90-minute nap, especially when it came to the tasks corresponding with the sound cues played during their sleep. This meant moving the cursor far more quickly and more directly towards the target. Participants also activated fewer superfluous arm muscles to execute the same motion as previously.

The results show that TMR during sleep can contribute to the learning of new motor skills: the researchers conclude that sleep can support memory storage and development; and could facilitate neurorehabilitation, such as aiding the recovery of stroke patients, for example, or in other types of therapy.
