Sleep is vital for the process of memory formation.

Scientists have known for some time that sleep is vital for the process of memory formation. Recently, British scientists have demonstrated that while asleep, the brain doesn’t simply 'overwrite' multiple memories of a previous experience, but actually generates, stores and strengthens both the old and new versions alongside one another. "In this way, sleep is allowing us to use our memory in the most efficient way possible, enabling us to update our knowledge of the world and to adapt our memories for future experiences," explains lead researcher Scott Cairney.
