2. Brain Consolidation
Even though sleeping is considered to be a passive state, on the contrary, the brain remains profoundly active. Studies have suggested that in the interim of only the first few hours of your sleep, the waves of the brain paces down to almost a dormant level. It is the later and larger segment of the slumber when the actions of the brain undergo acute exhilaration. It consolidates to a great deal and stores up, from petty to vital memories within the hippocampus, day in and day out.
