1. What is the memory encoding speed?Initial encoding of stimuli occurs within milliseconds
2. What is the consolidation duration?Long-term memory maintenance can take minutes, days, or years to fully stabilize
3. What happens to my brain while I sleep that helps me remember things?While you sleep, your brain moves new memories from a temporary spot in the hippocampus to a permanent spot in the neocortex. This makes the memories stronger and easier to recall later.
4. Why do we need different sleep stages like NREM and REM for memory?NREM sleep, especially slow‑wave sleep, helps us remember facts and events. REM sleep helps us remember skills, habits, and feelings.

Synaptic Plasticity: The ability of synapses to strengthen or weaken over time, forming the basis of learning and memory.
Memory Consolidation: The neurobiological process by which labile memory traces are converted into stable, long-term memories.
Neural Replay: The reactivation of neural patterns experienced during a task, thought to occur during sleep to strengthen memories.
