We have long been told a simple story about reward: Dopamine is the "wanting" molecule that drives us toward goals, and ...

Some people bounce back from trauma, but others get caught in depressive loops that sap the joy from their lives. Researchers at UCSF find a brain signature of resilience in mice that suggests a new ...

Researchers discover a new dopamine signal in the striatum that acts as a guidance system, encoding trajectory errors to steer behavior toward goals.

Using computational models, the researchers studied how the brain's reward-learning system functions in those with depression, especially among individuals experiencing anhedonia, the inability to ...

I was a third-year medical student at Northwestern on my ICU rotation the first time I saw a dopamine drip. The patient was pale and motionless, his blood pressure dropping by the minute despite large ...

Using computational models, the researchers studied how the brain's reward-learning system functions in those with depression, especially among individuals experiencing anhedonia, the inability to ...

Researchers discover a neural circuit that rewards gnawing behavior with dopamine, explaining repetitive oral habits in animals and humans.

When faced with multiple food options and ultimately choosing one, the factors of that decision-making process may be more physiological than previously assumed. A group of scientists led by ...
