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.
