This study compares task-switching neural distinctiveness in children and adults using fMRI, finding similar switch-related reductions but differences in regional correlations.

This study investigates how cognitive fatigue affects effort-based decision-making using fMRI, finding that fatigued individuals are more likely to choose lower reward options requiring less effort.

The paper investigates the functional organization of the human lateral prefrontal cortex using fMRI, revealing category-biased patches adjacent to domain-general regions.

The paper manipulates subjective time perception and shows its effects on delay discounting impulsivity and associated neural activity.

The paper investigates how two neural signals encode different aspects of belief formation during decision-making in a volatile task, finding that one signal tracks evolving beliefs while the other encodes belief updates.

The paper investigates how stimulus representation in the frontal cortex supports flexible control in working memory using fMRI and simulations.

This paper proposes a meta-Reinforcement Learning framework to unify theories of anterior cingulate cortex function in cognitive control and surprise monitoring, showing it explains neuroimaging data better than previous models.

This study constructs ex-Gaussian RT-signatures from reaction time data and finds higher similarity across participants for incongruent stimuli compared to congruent stimuli.

This study compares the subjective effort costs of distractor resistance and flexible updating in working memory tasks, finding that distractor resistance is more effortful.

The paper investigates neural mechanisms of credit assignment for delayed outcomes using fMRI and an adaptive learning task, identifying roles for lOFC, HC, and lFPC in tracking causal choices over time.

This study compares intensive task-switching training and single-task training in children, finding that task-switching training leads to sustained improvements in cognitive control and neural efficiency.

This study shows that rats exhibit distinct heart rate changes before and after selecting risky versus certain options in a gambling task.

This study examines how acute moderate alcohol consumption affects the speed of endogenous and exogenous attention shifts, finding that alcohol slows all types of attentional shifts equally.

This study uses intersubject correlation analysis on fMRI data to identify brain regions with synchronized neural responses to naturalistic emotional stimuli across participants.

The paper examines amygdala subregion volumes and apportionment in preadolescents, finding age-related expansion, sex differences, and associations with BMI.

This study shows that adolescent alcohol exposure leads to sex-specific changes in response inhibition and orbitofrontal-striatal activity, with increased adult alcohol consumption in males.

This study identifies reward circuitry activity predictive of risk-taking in humans using local field potential recordings during a gambling task.

This study uses EEG to examine how neural patterns dynamically represent and reconfigure information during novel verbal instruction tasks, revealing changes in dimensionality and abstraction over time.

This paper uses a meta-analysis of neuroimaging studies to show that exploration and exploitation decisions activate distinct brain regions, with some overlap suggesting complex interactions.

This study investigates whether rare events enhance working memory representations by examining P3b responses and behavioral accuracy in an oddball paradigm.

This study shows a neural network model of prefrontal cortex and basal ganglia can adapt chunking strategies to improve working memory capacity, mimicking human performance and linking it to dopaminergic signals.

The paper analyzes response-selective stopping using EMG and behavioral data from 17 cohorts, revealing overlaps in timing of action cancellation and re-programming, suggesting a 'pause-then-retune' mechanism.

This review identifies a multifactorial etiology and neurobiology of IED, highlighting the amygdala and orbitofrontal cortex, serotonergic signaling, and childhood trauma as key factors.

The paper introduces a gated accumulator model to explain how predictions of sensory timing influence choice anticipation and evidence accumulation during free choice saccade tasks.

This study shows the anterior cingulate cortex supports persistence toward certain and valuable rewards in both information and effort choices.

The paper extends a hybrid RL model with a heuristic-based exploration mechanism to analyze two-step sequential decision tasks, finding it better explains choice probabilities in stage one.

This study identifies common and unique neurophysiological signatures for action stopping and revising, revealing two distinct phases of inhibitory control.

The paper uses NLP and neuroimaging meta-analyses to show that arousal has seven varieties but a domain-general cortical network underlies most, reconciling opposing views on arousal.

This study examines neural activity in primate dlPFC during saccadic movements, finding that retrospective representations of recent saccades are reliable, while prospective planning-like activity is limited to reward-eligible saccades.

The paper investigates distractor-response binding in visual search, finding that response priming is stronger when distractor features or target positions are repeated, indicating DRB occurs at late stages of target identification and response selection.
