A structural MRI marker predicts individual differences in impulsivity and classifies patients with behavioral-variant frontotemporal dementia from matched controls

The paper develops a structural MRI signature of impulsivity using machine learning, validates it across multiple samples, and shows its diagnostic value in behavioral-variant frontotemporal dementia.

Common and distinct neural correlates of music and food-induced pleasure: a coordinate-based meta-analysis of neuroimaging studies.

This study compares the neural correlates of music and food-induced pleasure using a meta-analysis of 38 neuroimaging studies, finding common and distinct brain regions involved.

Predicting future drinking among young adults:using ensemble machine-learning to combine MRI with psychometrics and behaviour

The paper uses ensemble machine learning to predict future drinking in young adults by combining MRI, psychometric, and behavioral data, finding that specific neuroimaging and non-neuroimaging factors are strong predictors.

Cue-reactivity and approach bias to social alcohol cues and their association with drinking in a social setting in young adults

The paper examines brain and behavioral responses to social alcohol cues and their link to drinking in a social setting, finding no significant association.

Altered orbitofrontal sulcogyral patterns in gambling disorder: a multicenter study

This study finds a skewed distribution of orbitofrontal sulcogyral patterns in gambling disorder, with increased prevalence of Type II patterns compared to healthy controls.

Brain responses to anticipating and receiving beer: Comparing light, at-risk, and dependent alcohol users

The paper examines brain responses to beer anticipation and consumption in different drinking groups, finding reward network activation but no group differences.

The contribution of striatal pseudo-reward prediction errors to value-based decision-making

This study investigates how pseudo-reward prediction errors in the striatum influence value-based decision-making, finding that they bias choices even without actual reward.

Spontaneous eye blink rate and dopamine synthesis capacity: Preliminary evidence for an absence of positive correlation

The paper investigates the relationship between spontaneous eye blink rate and striatal dopamine synthesis capacity using PET imaging and finds no positive correlation, suggesting caution in interpreting sEBR as a proxy for dopamine function.

Dopaminergic drug effects on probability weighting during risky decision-making

This study investigates how dopamine D2/D3 receptor antagonism affects probability weighting during risky decision-making in healthy individuals and pathological gamblers.

Can pornography be addictive? An fMRI study of men seeking treatment for problematic pornography use.

This study uses fMRI to examine neural responses to erotic and monetary cues in men with and without problematic pornography use, finding increased ventral striatum activation in those with PPU.

Reward learning deficits in Parkinson’s disease depend on depression

This study shows that Parkinson’s disease patients with depression have impaired reward and punishment reversal learning and reduced striatal BOLD signals.
