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.

Vijay Namboodiri and Ali Mohebi on the evolving story of dopamine’s role in cognitive function

Researchers discuss the classic stories of dopamine’s role in learning, ongoing work linking it to a wide variety of cognitive functions, and recent research suggesting that dopamine may help us "look back" to discover the causes of events in the world.
