* **Primary Focus: **
**Declarative & Episodic Memory** (facts, names, dates, structured
learning).
* **Mechanism: **
* **Sharp-Wave Ripples: ** During deep N3
sleep, the hippocampus replays memories recorded during the day and transfers
them to the neocortex for long-term storage.
* **Synaptic Downscaling: ** Non-essential
neural connections formed during the day are pruned, freeing up capacity for
new learning the following day.
### REM Sleep
* **Primary Focus: **
**Procedural, Emotional & Schema Integration**.
* **Mechanism: **
* **Emotional Decoupling: ** High cholinergic
and low noradrenergic levels allow the brain to reprocess traumatic or
emotional events without triggering a full stress/fight-or-flight response.
* **Creative Schema Integration: ** REM sleep
links newly acquired memories to existing long-term knowledge webs, fostering
novel problem-solving and creative insights.

## 3. Integrated Study
Summary
| Stage | Memory Type
Processed | Primary Function |
| :--- | :--- | :--- |
| **NREM (N1 - N3) ** |
Declarative / Factual / Spatial | Replays facts, transfers memories from
short-term (hippocampus) to long-term (cortex), physical tissue repair. |
| **REM** | Procedural /
Emotional / Abstract | Integrates new memories with existing knowledge
networks, processes emotional valence, motor skills rehearsal. |

Activation-Synthesis vs. Threat Simulation and explaining how NREM and REM work
together to consolidate memories.
