Disinhibition and reward sensitivity in relation to alcohol consumption by university undergraduates [PDF]
, 2009 Deficits of prefrontal cortex functioning and associated executive cognitive impairments are well-known correlates of chronic alcoholism and may reflect cumulative effects of high alcohol exposure.

Two spatiotemporally distinct value systems shape reward-based learning in the human brain [PDF]
, 2015 Avoiding repeated mistakes and learning to reinforce rewarding decisions is critical for human survival and adaptive actions. Yet, the neural underpinnings of the value systems that encode different decision-outcomes remain elusive.

A narrative review of reward sensitivity, rash impulsivity, and food addiction in adolescents
, 2021 Adolescence represents a neurodevelopmental period characterised by heightened reward drive and weaker inhibitory control, that may increase vulnerability to compulsive overconsumption of highly-palatable foods and food addiction.

Sensorimotor feedback loops are selectively sensitive to reward [PDF]
eLife, 2021 Although it is well established that motivational factors such as earning more money for performing well improve motor performance, how the motor system implements this improvement remains unclear. For instance, feedback-based control, which uses sensory feedback from the body to correct for errors in movement, improves with greater reward.

Inferior frontal cortex activity is modulated by reward sensitivity and performance variability [PDF]
, 2016 High reward sensitivity has been linked with motivational and cognitive disorders related with prefrontal and striatal brain function during inhibitory control. However, few studies have analyzed the interaction among reward sensitivity, task performance

Synchrony can destabilize reward-sensitive networks [PDF]
Frontiers in Neural Circuits, 2014 When exposed to rewarding stimuli, only some animals develop persistent craving. Others are resilient and do not. How the activity of neural populations relates to the development of persistent craving behavior is not fully understood. Previous computational studies suggest that synchrony helps a network embed certain patterns of activity, although the

Sensitivity to Temporal Reward Structure in Amygdala Neurons [PDF]
Current Biology, 2012 The time of reward and the temporal structure of reward occurrence fundamentally influence behavioral reinforcement and decision processes [1-11]. However, despite knowledge about timing in sensory and motor systems [12-17], we know little about temporal mechanisms of neuronal reward processing.

Anhedonia is associated with blunted reward sensitivity in first-degree relatives of patients with major depression [PDF]
, 2016 BACKGROUND: Anhedonia is a cardinal feature of major depression and is hypothesized to be driven by low motivation, in particular blunted reward sensitivity.
