Episode notes
Shift from Pleasure to Compulsion
- Addiction starts as impulsive pleasure-seeking but shifts into compulsive behavior driven by pain avoidance.
- This shift leads to loss of freedom and behaviors that violate personal ideals consistently.
Dorsal Shift in Addiction
- The brain shifts addiction control from the ventral to the dorsal striatum, automating and rigidifying behavior.
- The dorsal striatum overrides pleasure focus, making behaviors compulsive and insensitive to consequences.
Dynorphins Drive Compulsive Habits
- The dorsal striatum automates all habits, but addiction involves dynorphins releasing due to avoidance of pain.
- This pain-driven process hijacks habit mechanisms, making compulsive behaviors more likely.
