Dreaming of better moves: sleep boosts motor skills learned in your head

This study looked at how sleep affects the brain's ability to remember and improve motor skills that were learned just by imagining them. Fifty-one healthy right-handed adults practiced finger movement tasks in their minds, then had their brain activity measured with MEG scans before and after sleep. The goal was to understand which brain networks are involved in this sleep-related memory boost, which could help design better mental practice programs for people recovering from movement disorders.
