The paper links bradycardia states to approach-avoidance decision-making under threat, showing amygdala and dACC involvement in integrating value and physiological states.

This study shows frontal theta power predicts response inhibition success in a stop-signal paradigm, with higher theta preceding successful stops and shorter Stop-Signal Reaction Times.

This study investigates distractor suppression in visual search tasks, finding that foreknowledge of distractor locations improves suppression, independent of pre-distractor alpha-band activity.

The paper investigates how depression affects self-belief formation through altered neural responses to positive and negative feedback.

This study investigates how anticipated competition levels modulate preparatory brain activity and task performance using EEG and MVPA in a sex judgment task.

This study examines how arousal affects attentional priority and processing speed in young and older adults using eye movements, finding no arousal effect on priority in older adults but increased pupil size and decreased evoked responses.

The paper examines how pupil responses and confidence judgments relate to decision accuracy and behavioural adjustments in young and older adults, finding older adults show reduced pupil responses and overconfidence in noisy conditions.

This study investigates how decision-making evolves during initial learning in rats, finding that choice performance improves with experience while response slowing persists.

The paper shows that anticipatory activity in the anterior prefrontal cortex and hippocampus guides continuous stay-leave decisions when waiting for future rewards.

The paper investigates how prefrontal cortex neurons represent deliberation during ambiguous visual tasks in macaques, finding that categorical choices precede motor plan representations.

The paper shows that environmental regularities can bias reward learning by increasing confirmation bias and reducing the dimensionality of learning tasks.

This study uses a reinforcement learning model to examine how monkeys' motivation to earn symbolic reinforcers is influenced by task state values.

This study uses 7-Tesla fMRI to show that the human periaqueductal grey (PAG) shows bilateral BOLD increases during a working memory task without threat, suggesting a broader role in brain-body communication.

This study investigates how perceptual uncertainty and reward information influence decision-making through a human behavioral experiment and computational modeling.

This study investigates whether midfrontal theta and brain activity in aMCC/preSMA reflect proactive or reactive cognitive control mechanisms beyond response time effects in conflict tasks.

The paper examines neural volatility in the orbitofrontal cortex during affective processing in healthy aging, finding that higher volatility correlates with distinct affective experiences and uncertainty in older adults.

The paper identifies two separable valuation systems in prefrontal-limbic circuits of macaque monkeys, with one in OFC representing outcome flavor and another in vlPFC representing outcome probability.

The paper uses a control theoretic approach to analyze neural activity in macaques during a continuous pursuit task, revealing how latent control variables influence decision-making and change of mind.

The paper uses MEG to study reward processing in depression, finding hypoactivation in ventromedial frontal cortex and its correlation with anhedonia.

This study investigates how ERP components like P2 and P3 are modulated by misjudging social information validity during decision-making tasks with conflicting advice cues.

This study investigates how the ventromedial prefrontal cortex (vmPFC) supports persistence during goal pursuit by modulating attention, showing that vmPFC activity predicts individual differences in goal-oriented attention and persistence.

This paper develops a cross-species evidence accumulation task to compare perceptual decision-making in humans, rats, and mice, finding similar strategies but species-specific priorities in speed, accuracy, and reward optimization.

This study combines pupillometry and drift-diffusion models to analyze auditory category learning dynamics, showing that delayed trials reveal distinct learning markers and DDM parameters.

This study shows that ACC neurons encode chosen actions and their outcomes rather than cognitive states like attention or impulsivity in mice performing a task.

The paper investigates the relationship between implicit statistical learning and executive functions, finding a consistent negative correlation driven by verbal fluency and working memory.

The paper investigates how neuronal representations of reward and risk expectations differ between impulsive and less impulsive decision-makers during a risky choice task.

This study identifies overlapping neural mechanisms for evidence accumulation, confidence, and changes of mind in specific brain regions using intracranial recordings and computational modeling.
