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.

Reconstructing dopamine’s link to reward
The field is grappling with whether to modify the long-standing theory of reward prediction error—or abandon it entirely.

Dopamine and the need for alternative theories
Some experimental findings are inconsistent with the dominant model of reward prediction error, highlighting the need for alternative testable and falsifiable models for dopamine function.

Does a new theory of dopamine replace the classic model?
My answer would be no, but the model poses challenges that will sharpen our understanding of dopamine and learning.

Cocaine, morphine commandeer neurons normally activated by food, water in mice
Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.
