Episode notes
Not Just A Reward Signal
- Dopamine isn't simply a 'reward' chemical but a reinforcing signal that can teach both approach and avoidance.
- Increasing synaptic dopamine improves core ADHD symptoms, which explains stimulant effectiveness.
Titrate To A Dopamine Sweet Spot
- There is a therapeutic 'sweet spot' for dopamine transmission during medication titration.
- Too much synaptic dopamine worsens attention and can progress toward psychosis-like effects.
Dopamine As A Modulator, Not A Switch
- Dopamine acts like a transistor: it modulates other neurotransmitter circuits rather than acting as a simple on/off switch.
- Its presence changes how other chemicals (serotonin, oxytocin, endorphins) operate in the brain.
