Converging evidence from both human neuroimaging and animal studies has supported a
model of mesolimbic processing underlying reward learning behaviors, based on the …

Much human behavior is driven by rewards. Preclinical neurophysiological and clinical
positron emission tomography (PET) studies have implicated striatal phasic dopamine (DA) …

A prominent theory in neuroscience suggests reward learning is driven by the discrepancy
between a subject's expectation of an outcome and the actual outcome itself. Furthermore, it …

The extent to which we learn from positive and negative outcomes of decisions is modulated
by the neurotransmitter dopamine. Dopamine neurons burst fire in response to unexpected …

The dopaminergic mechanisms that control reward-motivated behavior are the subject of
intense study, but it is yet unclear how, in humans, neural activity in mesolimbic reward …

The attention system is shaped by reward history, such that learned reward cues
involuntarily draw attention. Recent research has begun to uncover the neural mechanisms …

During reinforcement learning, dopamine release shifts from the moment of reward
consumption to the time point when the reward can be predicted. Previous studies provide …

How does the brain translate information signaling potential rewards into motivation to get
them? Motivation to obtain reward is thought to depend on the midbrain [particularly the …

Reward has been shown to promote human performance in multiple task domains.
However, an important debate has developed about the uniqueness of reward-related …

Learning to optimally predict rewards requires agents to account for fluctuations in reward
value. Recent work suggests that individuals can efficiently learn about variable rewards …
