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 ...
Dopamine is a key neurotransmitter known to modulate motivation and reinforcement learning. While the role of dopamine in ...
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 ...
