Reward processing in schizophrenia and its relation to Mu opioid receptor availability and negative symptoms: A [11C]-carfentanil PET and fMRI study

NeuroImage: Clinical, 2023
Background: Reward processing deficits are a core feature of schizophrenia and are thought to underlie negative symptoms. Pre-clinical evidence suggests that opioid neurotransmission is linked to reward processing.

Your smile won’t affect me: Association between childhood maternal antipathy and adult neural reward function in a transdiagnostic sample

Translational Psychiatry, 2023
Aberrant activation in the ventral striatum (VS) during reward anticipation may be a key mechanism linking adverse childhood experiences (ACE) to transdiagnostic psychopathology.

The effects of an 8-week mindful eating intervention on anticipatory reward responses in striatum and midbrain

Frontiers in Nutrition, 2023
IntroductionAccumulating evidence suggests that increased neural responses during the anticipation of high-calorie food play an important role in the tendency to overeat. A promising method for counteracting enhanced food anticipation in overeating might

Reward anticipation in the adolescent and aging brain [PDF]

Human Brain Mapping, 2014
AbstractProcessing of reward is the basis of adaptive behavior of the human being. Neural correlates of reward processing seem to be influenced by developmental changes from adolescence to late adulthood. The aim of this study is to uncover these neural correlates during a slot machine gambling task across the lifespan.

Signals of anticipation of reward and of mean reward rates in the human brain [PDF]

Scientific Reports, 2019
Abstract Theoretical models of dopamine function stemming from reinforcement learning theory have emphasized the importance of prediction errors, which signal changes in the expectation of impending rewards. Much less is known about the effects of mean reward rates, which may be of motivational significance due to their role in ...

Autistic Traits Affect Reward Anticipation but not Reception. [PDF]

Sci Rep, 2020
AbstractAutism spectrum conditions (ASC) have been linked to aberrant reward processing, but it remains unclear whether it is a general dysfunction or limited to social stimuli, and whether it affects both phases of reward processing, namely anticipation and reception.

Reward Anticipation in Ventral Striatum and Individual Sensitivity to Reward: A Pilot Study of a Child-Friendly fMRI Task. [PDF]

PLoS ONE, 2015
Reward processing has been implicated in developmental disorders. However, the classic task to probe reward anticipation, the monetary incentive delay task, has an abstract coding of reward and no storyline and may therefore be less appropriate for use ...

Reward-related neural correlates in adolescents with excess body weight

NeuroImage: Clinical, 2021
The functional and connectivity reward processing in adults with excessive body weight is well documented, though is relatively less researched during adolescence. Given that reward and inhibition may be highly malleable during adolescence, it is unknown

Age-related differences in the anticipation of future rewards [PDF]

Behavioural Brain Research, 2011
The present study examined the anticipation of future reward in 7-mo- and 26-mo-old Fischer 344/Brown Norway rats. Young and old rats were divided randomly and assigned into one of two conditions. In the Contrast Condition, subjects were given a water solution containing 2% sucrose for 3 min followed immediately by a water solution containing 32 ...

Effect of familiarity on reward anticipation in children with and without autism spectrum disorders. [PDF]

PLoS ONE, 2014
BACKGROUND:Previous research on the reward system in autism spectrum disorders (ASD) suggests that children with ASD anticipate and process social rewards differently than typically developing (TD) children--but has focused on the reward value of ...
