Episode notes
Interoception Drives Motivation
- Interoception is the brain's ability to detect and interpret internal bodily signals like hunger, fatigue, and pain.
- These signals drive motivations and decisions by telling the brain when something needs attention.
Book Starts Naked In A Flotation Tank
- Caroline began her book with a flotation-tank scene to hook readers into science.
- She called it a deliberate ploy to get people interested and to feel internal signals up close.
Three Body→Brain Pathways
- The body-to-brain interoceptive messages travel via the spinal cord, the vagus nerve, and blood-borne signals like hormones.
- The brain constantly predicts incoming signals and updates those predictions in a continuous loop.
