How Does Sleep Improve Memory?

💡 The Answer

• During deep sleep, the brain replays and consolidates newly learned information for long-term storage.
• REM sleep, associated with dreaming, helps integrate emotional experiences into memory networks.
• Sleep spindles in non-REM sleep facilitate the transfer of memories from the hippocampus to the cortex.
• Lack of sleep impairs the ability to form new memories and retrieve existing ones effectively.
