We sleep for our brain to get rest.If we dream during a sleep is our brain getting rest?
During sleep our brain is, in fact, extraordinarily active. As it turns out, much of that activity helps the brain to learn and remember. Sleeping is involved in the learning and memory process in several important ways.A study conducted by The University of Chicago concluded that sleep helps the mind learn complicated tasks. It also helps people recover knowledge they thought they had forgotten over the course of a day.Sleeping consolidates learning by restoring what was lost over the course of a day, and by protecting against further loss. These findings suggest that sleep has an important role in learning specialized skills, and in stabilizing and protecting memory. This consolidation process may also help with language skills like reading and writing, as well as eye-hand skills such as tennis.A recent study offers new insights into the specific components of emotional memories. It suggests that sleep plays a key role in determining what we remember – and what we forget. Findings show that sleep helps the brain to selectively preserve and enhance certain aspects of a memory. Those with the greatest emotional value are enhanced, and simultaneously, those of lesser value are downgraded.
