Sleep

• Sleep and Memory ConsolidationLearning does not end when practice stops. Memories continue to change after encoding, and sleep is one important environment in which this consolidation occurs.
• Sleep ArchitectureA normal night's sleep is not eight hours of one state. The brain repeatedly cycles through N1 N2 N3 back toward lighter NREM REM, with the mixture changing over the night.
