Neural coding of reward-prediction error signals during classical conditioning with attractive faces
S Bray, J O'Doherty - Journal of neurophysiology, 2007 - journals.physiology.org
Attractive faces can be considered to be a form of visual reward. Previous imaging studies
have reported activity in reward structures including orbitofrontal cortex and nucleus …

The neural mechanisms underlying the influence of pavlovian cues on human decision making
In outcome-specific transfer, pavlovian cues that are predictive of specific outcomes bias
action choice toward actions associated with those outcomes. This transfer occurs despite no …

Direct instrumental conditioning of neural activity using functional magnetic resonance imaging-derived reward feedback
S Bray, S Shimojo, JP O'Doherty - Journal of Neuroscience, 2007 - Soc Neuroscience
Successful learning is often contingent on feedback. In instrumental conditioning, an animal
or human learns to perform specific responses to obtain reward. Instrumental conditioning is …

Human medial orbitofrontal cortex is recruited during experience of imagined and real rewards
S Bray, S Shimojo, JP O'Doherty - Journal of …, 2010 - journals.physiology.org
Human decision-making frequently relies on mental simulation of future rewards to guide
action choice. In this study, we sought to uncover brain regions engaged during reward …
