Drug seeking is associated with activation of reward neural circuitry. Here we argue that
drug addiction also involves a'dark side'—a decrease in the function of normal reward�…

Although cells in many brain regions respond to reward, the cortical-basal ganglia circuit is
at the heart of the reward system. The key structures in this network are the anterior�…

Over the past few decades, neuroscience research has illuminated the neural mechanisms
supporting learning from reward feedback. Learning paradigms are increasingly being�…

Following the suggestion that midbrain dopaminergic neurons encode a signal, known as a
'reward prediction error', used by artificial intelligence algorithms for learning to choose�…

This review outlines recent findings from human neuroimaging concerning the role of a
highly interconnected network of brain areas including orbital and medial prefrontal cortex�…

Previous research has shown that two components of the event-related brain potential, the
P300 and feedback negativity, are sensitive to information about rewards and penalties. The�…

What roles do mesolimbic and neostriatal dopamine systems play in reward? Do they
mediate the hedonic impact of rewarding stimuli? Do they mediate hedonic reward learning�…

A key component to rational decision-making and appropriate goal-directed behaviors is the
ability to evaluate reward value, predictability, and risk accurately. The reward circuit, central�…

The discovery that dopamine neurons signal errors in reward prediction has demonstrated
that concepts empirically derived from the study of animal behavior can be used to�…

Rewards have been examined extensively by both psychologists and neuorscientists and
have become one of the most contentious issues in social and educational psychology. In�…
