This paper introduces a hierarchical Bayesian model to explain how the brain balances habitual and goal-directed behavior through context-specific learning and probabilistic inference.

The paper examines age, sex, and puberty effects on amygdala subregion volumes and proportions in adolescents, finding age drives these changes in males.

The paper examines neural responses to outcomes in the iterated prisoner's dilemma game using EEG, identifying specific brain signals that predict future cooperation decisions based on previous outcomes.

This study investigates how reward value and temporal gaps affect express saccades in rhesus macaques, finding that express saccades are insensitive to target value but responsive to salience.

This study investigates how visuo-vestibular mismatches affect value attribution to positive and negative reinforcers using a modified Flankers task with galvanic vestibular stimulation.

This study uses fMRI to show that frontoparietal brain regions contain both procedural and declarative representations of novel instructions, with procedural activation predicting behavioral performance.

This study tests if social conformity and reinforcement learning share a common neural mechanism using fMRI and finds no clear evidence of such a shared mechanism.

This study identifies distinct roles of prefrontal cortex projections in modulating sensorimotor behavior through separate circuits for motor response coordination and sensory cue processing.

This study links the timing of readiness potentials to evidence accumulation in decision-making, showing that RP duration predicts decision time and reflects response selection in the motor system.

This study shows that value-based decision making in monkeys occurs in the action domain of the prefrontal cortex, not through an intermediate stimulus-based stage.

This paper introduces a neural network framework called DynaMoE to model how the prefrontal cortex encodes, stores, and switches between schemas, demonstrating transfer learning and memory savings.

This study shows that electrical stimulation of orbitofrontal cortex in rhesus monkeys biases economic choices by altering encoded values.

The paper uses chemogenetic techniques to show that the anterior cingulate cortex and its projections to the anterior thalamic nuclei are involved in attention to task-relevant information and cognitive flexibility in rats.

This paper examines β-bursts in EEG during saccade countermanding tasks in macaques, finding they are too infrequent to explain stopping behavior and show no response time adaptation.

This study links longitudinal decline in executive function with increased prefrontal and amygdala activation during emotion reappraisal and reduced white matter integrity in older adults.

The paper shows that expecting social punishment reduces decision noise under uncertainty by engaging the medial prefrontal cortex, while worsening mood.

The paper links individual differences in social reward and threat expectancies to grey matter volumes in specific brain regions using structural MRI and voxel-based morphometry.

The paper shows that subjective value and decision entropy are encoded by aligned gradients across the human brain, with value areas more strongly signaling decision entropy than value itself.

This study investigates how reward learning influences spatial attention by identifying neural correlates in brain regions associated with value-driven attention.

The paper investigates how the brain represents task-dependent errors during adaptive learning using fMRI and multi-voxel pattern classification.

The paper uses a machine learning model to identify EEG features distinguishing Go and NoGo conditions in a task, achieving 92% accuracy and localizing brain regions involved in selection and inhibition.

The paper tests if a dimensional framework can link error-related negativity (ERN) to psychiatric symptoms but finds no significant associations.

This study shows that stimulating the orbitofrontal cortex impairs decision-making based on inferred outcomes but not on direct experience.

This study uses fMRI and multivariate pattern analysis to show that the ventral pre-supplementary motor area responds similarly to conflict and affect tasks, challenging the idea that these processes are independent.

The paper examines neural responses to criticism from different relationship types using fNIRS, finding varied prefrontal cortex activation based on perceived criticism levels.

This study identifies three neurocognitive subtypes of depression in youth using machine learning, showing distinct neural signatures despite similar clinical symptoms.

This study compares how adolescents and adults adjust learning rates and exploration based on uncertainty over time, finding adolescents overestimate environmental volatility leading to higher learning rates and exploration.

Unexpected sounds suppress visual stimulus representations in an attentional task, revealing a role for inhibitory control mechanisms in attentional disruption.

This study examines neural correlates of binge-watching during response inhibition and performance monitoring using EEG, finding increased P3 and ERN in high binge-watching participants.

The paper shows that choosing negative stimuli activates reward circuitry similar to extrinsic incentives and curiosity, contrasting with positive stimuli choices.
