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 ...

New look at dopamine signaling suggests neuroscientists' model of reinforcement learning may need to be revised
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 ...
Humans and most other animals are known to be strongly driven by expected rewards or adverse consequences. The process of ...
Dopamine is a key neurotransmitter known to modulate motivation and reinforcement learning. While the role of dopamine in ...
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 ...
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 ...
Visualization of sequential neuronal activity in the medial prefrontal cortex of mice at different learning stages—from novices (days 1–2) to experts (day 6)—during successful and failed reward ...
