Research in mice identifies brain circuitry that supports certain reward-based decisions. Every day, our brain makes thousands of decisions, big and small. Any of these decisions -- from the least ...

Dopamine is a powerful signal in the brain, influencing our moods, motivations, movements, and more. The neurotransmitter is crucial for reward-based learning, a function that may be disrupted in a ...

Research shows that reward-based learning requires the two neuromodulators to balance one another's influence -- like the accelerator and brakes on a car If you've heard of two of the brain's chemical ...

If you reward a monkey with some juice, it will learn which hand to move in response to a specific visual cue – but only if the cerebellum is functioning properly. So say neuroscientists at the ...

Learning is essential in everyday life. Whenever we make a choice, we need to know whether to repeat it or to try a different course of action. But what makes us learn or prevents us from learning? A ...

In a study in the Journal of Affective Disorders, Fralin Biomedical Research Institute scientists Pearl Chiu and Brooks Casas investigate how brain signals involved in reward learning might help ...

In the other session, participants only got "reward feedback," with successful shots being artificially shown pocketing, while failed shots gave no visual results. The goal was to see whether the ...
