Episode notes
Memory Prioritizes Future Guidance
- Human memory prioritizes generalization over perfect recall to guide future decisions.
- Memories evolve to support survival by focusing on useful knowledge, not exact details.
Memory Types Use Different Systems
- Memory is not one uniform system; different types like episodic and implicit memories use different brain systems.
- Episodic memories involve what, where, and when; implicit memories include skills like riding a bike.
Memories Strengthen Neuronal Connections
- Memories form through the strengthening of connections between neurons, especially at synapses.
- Enhanced synaptic communication signals that a memory has been learned and solidified.
