A brain signature of vaping cue-elicited craving

The paper develops a brain signature for vaping cue-elicited craving using fMRI and validates its distinction from smoking and food craving signatures, linking it to e-cigarette dependence.

Hippocampus mediates conceptual generalization of pain modulation

The paper investigates how conceptual generalization influences pain experience and shows that the hippocampus mediates this effect through cue-evoked expectations.

Brain neuromarkers predict self- and other-related mentalizing across adult, clinical, and developmental samples

The paper develops fMRI classifiers to predict self- and other-related mentalizing, showing high accuracy and distinct neural patterns across different populations and conditions.

Convergent and selective representations of pain, appetitive processes, aversive processes, and cognitive control in the insula

The paper identifies convergent and selective functional zones in the insula using fMRI data, revealing a hierarchical convergence architecture across pain, appetitive, aversive, and cognitive control domains.

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.

High delay discounting relates to core symptoms and to pulvinar atrophy in frontotemporal dementia

This study finds that frontotemporal dementia patients show higher delay discounting, linked to impulsivity symptoms and pulvinar atrophy.

How motivational interviewing shifts food choices and craving-related brain responses to healthier options

This study shows that motivational interviewing shifts food choices and reduces craving-related brain responses to healthier options by altering value-based decision-making.

Odor imagery but not perception drives risk for food cue reactivity and increased adiposity

The paper investigates how odor imagery, not perception, influences food cue reactivity and adiposity in healthy individuals.

Effect sizes and test-retest reliability of the fMRI-based Neurologic Pain Signature

The paper evaluates the effect size and test-retest reliability of the Neurologic Pain Signature (NPS) across multiple studies, finding large within-person effect sizes and reliable performance with sufficient trial numbers.

An fMRI-based brain marker predicts individual differences in delay discounting

The paper develops an fMRI-based brain marker predicting individual differences in delay discounting using machine learning, showing significant prediction accuracy in two independent studies.

Evoked pain intensity representation is distributed across brain systems: A multistudy mega-analysis

This study investigates the spatial scale of acute pain representation using fMRI data from 289 participants, finding that distributed, multi-system models better capture pain intensity than single regions or networks.

Multiple brain networks mediating stimulus-pain relationships in humans

The paper identifies brain networks mediating stimulus-pain relationships using high-dimensional mediation analysis in fMRI data from 284 humans.

A generalizable multivariate brain pattern for interpersonal guilt

The paper identifies a brain pattern specific to interpersonal guilt using neuroimaging data from two independent populations.
