Extra brain processing during sleep enhances learning of new motor skills.
Practice makes perfect, but sleep helps, too. Learning and executing a new motor skill can be enhanced if you can get additional memory processing during sleep, according to new research published in JNeurosci.
Researchers at Northwestern University compared how well participants performed a challenging motor task with and without the extra processing during sleep. The participants played a …
