Episode notes
Brain's Primary Role
- The brain's main job is regulating the body, not just thinking or feeling.
- It manages internal systems like heart rate and supports movement, impacting how we experience the world.
Debunking the Triune Brain
- The triune brain model (lizard brain, limbic system, cortex) is outdated and doesn't reflect current evidence.
- Mammalian brains share a similar developmental plan, differing mostly in the duration of developmental stages.
Brain as a Network
- The brain functions as a dynamic network, not isolated modules.
- Neurons compute features through relationships and patterns, rather than acting as separate mental organs.
