Sleep's memory role discovered.

Is it better to study and have a good night's sleep rather than keep studying? Read on to find out...
The mechanism by which a good night's sleep improves learning and memory has been discovered by scientists.
The team in China and the US used advanced microscopy to witness new connections between brain cells - synapses - forming during sleep.
Their study, published in the journal Science, showed even intense training could not make up for lost sleep.
Experts said it was an elegant and significant study, which uncovered the mechanisms of memory.
It is well known that sleep plays an important role in memory and learning. But what actually happens inside the brain has been a source of considerable debate.
Researchers at New York University School of Medicine and Peking University Shenzhen Graduate School trained mice in a new skill - walking on top of a rotating rod.
They then looked inside the living brain with a microscope to see what happened when the animals were either sleeping or sleep deprived.
Their study showed that sleeping mice formed significantly more new connections between neurons - they were learning more.
