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 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 ...

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 ...

Researchers at University of Tsukuba and their collaborators have demonstrated that learning from both rewarding and aversive outcomes requires a common brain molecule, sulfatase 1 (Sulf1). This ...

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 ...

Dopamine is a key neurotransmitter known to modulate motivation and reinforcement learning. While the role of dopamine in these reward-related processes is well-established, the cellular and neural ...

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 ...
