Episode notes
Dopamine Is The Brain's Motivation Signal
- Dopamine is a brain chemical that signals reward, motivation, and survival relevance.
- It drives our motivation more than raw pleasure, making us seek what we need to survive.
Dopamine-Less Rats Starved Despite Food
- Rats engineered without dopamine would eat food in their mouth but starve if the food required effort to obtain.
- This shows dopamine is necessary for motivated action, not just experiencing pleasure.
Addiction Is Not To Dopamine Itself
- We do not get addicted to dopamine itself; dopamine is a neutral signal about reward prediction.
- Addiction arises when behaviors hijack this signal and the brain's reward-pain balance is disrupted.
