Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning

Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.
