Episode notes
Memory and Models
- Memories are instantiated in synapses, reflecting knowledge and models of the world.
- These models, constantly updated, encompass everything from physical objects to human behavior.
Brain's Centrality
- While collective intelligence is significant, the brain remains central to all theories of intelligence.
- Understanding individual brains is crucial before examining their interactions and knowledge sharing.
Thousand Brains Theory
- The Thousand Brains theory proposes that the neocortex consists of thousands of independent modeling systems.
- These systems, called cortical columns, learn complementary models and communicate through voting.
