A new study shows once again the restorative powers of sleep. The research from the University of Notre Dame looked at the impact of sleep on memory. It found that slumber may not only help fix memories in the brain for later retrieval but also reconfigure them.
Researchers tested participants before and after sleep, and measured brain activity while the subjects slept. The study, which was published in Psychological Science, found that sleep helps in reorganizing memories, picking out emotional details and may even help in taking memories apart to create new ideas.
The co-author of the research said we can get away with less sleep, but says she believes that sleep deprivation a profound effect on our cognitive abilities.
