The paper examines how neural responses to social and nonsocial fairness relate to financial exploitation vulnerability, showing age and emotional intelligence modulate these associations.

The paper examines how striatal social reward sensitivity predicts trust-related brain responses, showing interactions with social closeness and depression.

The paper examines how individual differences in other-directed emotion regulation relate to neural and behavioral responses during fairness decisions in social contexts.

This paper investigates the reward response using intraindividual fMRI data, finding low between-person reliability and significant within-person variance explained by mood and alertness.

This study shows that α-tACS over VLPFC modulates pupil responses and corticostriatal connectivity during reward processing.

The paper investigates how social closeness and individual differences in reward sensitivity and substance use affect ventral striatal activation and connectivity during shared reward experiences.

The paper investigates how neural responses to betrayal and unfairness are linked through insula-valuation network dynamics in social exchange tasks.

This study examines how aging affects brain network connectivity during fairness decisions in an ultimatum game, finding age-related differences in default mode and executive control network interactions.

The paper investigates how the cerebellum and ventral striatum process social rewards using fMRI, finding the cerebellum responds uniformly to feedback regardless of reward valence, unlike the striatum.

This paper uses a meta-analysis of neuroimaging studies to show that exploration and exploitation decisions activate distinct brain regions, with some overlap suggesting complex interactions.

This study examines how trait reward sensitivity influences neural connectivity patterns during strategic decision-making tasks using fMRI.

The paper investigates how affective and informative reward components are represented in the striatum and hippocampus using high-resolution fMRI and representational similarity analysis, finding differential coding in the dorsal and ventral striatum.

The paper examines how reward sensitivity and subclinical substance use relate to striatal function during social rewards, finding nuanced neural correlates linked to potential risk for substance use disorder.

This paper applies tensorial ICA to fMRI data to identify brain networks associated with MDD, finding reduced coherence in three networks involving vmPFC, striatum, and cerebellum.

The paper investigates how reward affects connectivity between the default mode network and the ventral striatum during a task, finding it correlates with personality openness.

This study examines age-related differences in brain responses to reciprocated trust using fMRI, finding reduced striatal responses and altered default-mode network connectivity in older adults.

The paper examines changes in cerebellar connectivity with the substantia nigra and ventral tegmental area in Parkinson's disease using resting-state fMRI data, finding a double dissociation in connectivity patterns.

The paper investigates how family history of depression affects neural connectivity in the brain during social cognition and reward processing tasks.

This study maps brain regions involved in social reward and punishment processing using a voxel-based meta-analysis of fMRI data from the Social Incentive Delay task.

This study uses meta-analysis to parcellate the default mode network into functionally distinct subcomponents and assesses their associations with cognitive processes and health conditions.

This study investigates how relationship closeness affects default-mode network connectivity during social interactions involving trust.

This study finds that higher body mass index is linked to reduced gray matter volume in the right orbitofrontal cortex in a meta-analysis of neuroimaging data.

This study performs a meta-analysis of neuroimaging data to show that major depressive disorder is associated with opposing abnormalities in the reward circuit, including hypo-responses in the ventral striatum and hyper-responses in the orbitofrontal cortex.

The paper investigates gain/loss framing biases in decision-making using fMRI data, finding that biased decisions correlate with default brain states rather than emotional processes.
