How rest enhances language learning?

Sleep is critical for all sorts of reasons, but a team of international scientists has discovered a new incentive for getting eight hours of sleep every night: it helps the brain to store and learn a new language. A study led by the University of South Australia (UniSA) and published in the Journal of Neuroscience has revealed that the coordination of two electrical events in the sleeping brain significantly improves our ability to remember new words and complex grammatical rules.
