The paper uses computational modeling and fMRI to investigate how environmental uncertainty influences premature decision-making impulsivity in humans.

This study shows that high SPS-like rats have increased cocaine self-administration and altered glutamatergic/GABAergic signaling in the prefrontal cortex, suggesting a risk factor for cocaine use disorder.

This study compares serum tryptophan pathway alterations in chronic METH and MDMA users, finding distinct metabolic changes linked to psychiatric symptoms.

This study uses fMRI and multivariate pattern analysis to show that wanting-related brain patterns persist longer in individuals with nicotine use disorder, supporting the Incentive-Sensitization Theory.

The paper investigates plasma endocannabinoids in cocaine dependence and their relationship with mGluR5 density in the brain, finding higher 2-AG levels in dependent users and a positive association with mGluR5 density.

This study shows that opioid antagonism reduces reward wanting by enhancing frontostriatal connectivity in humans.

The paper examines how morphine affects cortisol response to stress and links it to changes in negative mood and social reward seeking in humans.

This study finds that chronic cocaine users show altered sensitivity to gain information during risky decision-making, leading to increased risk-seeking in unfavorable scenarios.

This study shows that cocaine users can self-regulate their reward system using non-drug imagery and that real-time fMRI neurofeedback enhances this ability.
