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.

The paper investigates patch-leaving decisions using pupil dilation as a measure of neuromodulation, finding increased pupil dilation before leave decisions and linking it to LC-NE activity.

This study shows that stopping speed in rats varies across sessions and is not a fixed trait, suggesting SSRTs should be treated as state-like variables in multi-session stop-signal tasks.

The paper investigates how lactate levels in the dmPFC/dACC relate to motivation for physical effort and neural activity, finding a systemic influence of lactate on brain metabolism.

This study investigates how reward prospects affect cognitive processing under different task specificity conditions, finding that reward enhances preparatory top-down attention in a task-specific manner.

This study shows that defensive freezing enhances threat-reward processing in the dACC during approach-avoidance decisions, improving decision-making under threat.

This study uses intracerebral stimulation to show that different locations in ventromedial prefrontal cortex and anterior insula have opposing effects on economic choices.

This study identifies distinct OFC-subcortical pathways in macaques that support experience-based and inference-based value updating during adaptive decision-making.

This study examines how anhedonia severity affects attentional network recruitment and emotional blunting during music listening in healthy adults.

This meta-analysis examines how Flanker task parameters affect ERN-anxiety associations, finding that response type and block-level feedback significantly influence effect sizes.

This study shows that neural activity patterns in the prefrontal cortex predict cognitive improvements during adolescence, with long-distance white matter tracts playing a key role.

This study investigates the neural mechanisms of fast versus slow decision-making in mice using a novel floating-platform system and neuroimaging, revealing distinct roles for medial and lateral frontal cortex.

This study identifies distinct roles of prefrontal cortex neuron subtypes in cognitive flexibility during set shifting in mice.

The paper shows mice adapt perceptual choice history biases to different temporal regularities, supported by a reinforcement learning model and striatal dopamine signals.

The paper shows that prediction-error signals in the anterior cingulate cortex are necessary for rapid task-switching in mice, with specific neural circuits involved in computing these signals.

This paper models how the brain computes delayed consequences in decision-making without explicit feedback, showing how neural dynamics and learning mechanisms adapt over time.

The paper investigates how change and uncertainty affect pupil-linked brain arousal during belief updating using a probabilistic reversal learning task.

This study separates the neural bases of selective attention and decision-making using a two-stage task and multimodal neuroimaging data, showing attention affects stimulus representations before decision-making begins.

This study investigates how stake magnitude affects Pavlovian biases and response speed in humans, finding that high stakes slow responses without altering bias magnitude.

The paper shows that GABA in the dACC affects appetitive and aversive learning through distinct mechanisms involving different brain regions and connectivity patterns.

This study examines sex differences in contextual control over reward prediction in rats, finding females show slower acquisition but more robust performance with increased orbitofrontal cortex activation.

The paper uses fMRI and Bayesian modeling to show that premotor cortex and intraparietal sulcus encode perceptual decisions independently of motor actions and sensory modalities.

This study examines the unity/diversity framework of executive functions in older adults using behavioral and neural data, finding support for the unity/diversity construct.

The paper shows that during decision-making, macaques' gaze at empty locations reactivates value encoding in orbitofrontal cortex, influencing choices even after offers are no longer visible.

The paper shares a dataset of cognitive tasks, anatomical MRI, and functional MRI data from 103 healthy adults to study self-regulation.
