This study uses cTBS to inhibit the left DLPFC in older adults and finds that it disrupts verbal working memory by prolonging P200 latency, suggesting impaired early attentional gating.

This study shows that aging and loneliness impair trust learning through reduced amygdala function and altered reward signaling.

This paper identifies a frontal motor circuit that transforms abstract economic decisions into spatial actions through dynamic reconfiguration.

The paper shows high trait anxiety impairs reward learning in noisy environments but not volatile ones, and N3 sleep improves learning and evidence accumulation.

The paper shows cardiac-sympathetic outflow predicts action restraint during a task, with effects modulated by reward and loss conditions and participant success.

This paper shows that environmental conflict reduces Pavlovian avoidance and increases instrumental choice, especially in individuals with high trait anxiety.

This study uses real-time fMRI neurofeedback to train individuals to regulate DLPFC-amygdala connectivity during threat exposure, reducing anxiety.

The paper identifies functionally distinct adjacent regions in the dorsolateral prefrontal cortex (DLPFC) specialized for social and cognitive control tasks using individualized neuroimaging.

This study uses multi-task intracranial EEG recordings to investigate the role of the human dorsal anterior insula in various cognitive tasks, revealing its involvement in the Action-Mode Network and the interplay between cognitive effort and efficiency.

This study shows that noradrenergic signaling in the orbitofrontal cortex adjusts learning rates based on environmental volatility, improving adaptive decision-making in rats.

The paper investigates general forms of stochastic dependence that imply a probability inequality in race models of cognitive tasks, using copulas and heavy-tailed distributions.

The paper uses fMRI decoding to show that neural activity in the posterior putamen during learning predicts individual differences in habit versus goal-directed behavior across multiple cohorts.

This study investigates how working memory generalization occurs across tasks in human parietal and frontal cortices using functional MRI experiments.

The paper tests whether movement and decision vigor are co-regulated or decoupled in a reward task, finding they are mostly decoupled and driven by distinct time-cost signals.

The paper examines EEG and pupillometry signals during reward learning, showing that an early neural signal following negative feedback is linked to uncertainty and improved learning through network resets.

The paper investigates how neural responses to betrayal and unfairness are linked through insula-valuation network dynamics in social exchange tasks.

This study shows that subjective value signals in the brain's valuation circuits can be computed without conscious awareness of the stimuli.

This study shows that the primate orbitofrontal cortex is specifically involved in value-based decisions but not perceptual decisions, indicating functional specialization.

The paper shows that multidimensional attentional control involves reactive suppression of distractor representations in human EEG, guided by a structured multivariate conflict signal.

The paper develops mixture-model classes for stimulus-selective stopping and applies them to a published dataset.

The paper develops a neurocomputational model of hierarchical decision-making that captures trial-by-trial variability and reproduces human behavioral patterns.

The paper investigates whether the centro-parietal positivity (CPP) EEG component reflects evidence accumulation in perceptual and mnemonic decisions, finding it scales with evidence strength, response time, and confidence across tasks.

This study uses EEG to investigate covert habit activation and control in humans, finding that the lateralized readiness potential tracks habitual responses and frontal midline theta power scales with habit override.

This study uses cTBS to inhibit the vmPFC and shows reduced Go responses, slower reaction times, and increased reward prediction error signals in subcortical regions.

This study shows that ventromedial prefrontal cortex (vmPFC) excitability decouples value computations from physiological arousal during normative decision making, increasing selfishness in social interactions.

The paper investigates how the brain encodes value signals for pleasant and unpleasant scenarios, showing distinct neural systems in vmPFC and aIns that guide decision-making.

This study examines how modulating tonic arousal affects attentional processing in children and adults, finding no effect of arousal modulation but stronger phasic responses in children to novel stimuli.

The paper identifies distinct neural pathways for evaluative and informational social influence using EEG and the Judge-Advisor System, showing feedback and advice engage different processing routes.

This study investigates how the substantia nigra pars reticulata encodes decision-making in monkeys, showing a shift from representing optimal choices to encoding actual selections during the decision process.
