This study shows that orbitofrontal cortex activity predicts both economic choice and stopping in macaques, suggesting shared neural processes for these tasks.

This study examines how working memory load affects neural responses to targets and distractors during visual search, finding impaired distractor processing with increased load.

This study investigates how aversive emotions affect trust decisions and the associated neural circuitry, showing reduced trust and altered connectivity in specific brain regions.

The paper shows that the medial prefrontal cortex network computes value homeostasis by tracking imbalance and redress in goal-related assets during decision-making.

The paper tests three theoretical models of dorsal anterior cingulate cortex using a value-based decision-making task and finds the Predicted Response-Outcome model best explains the results.

The paper uses EEG to show that retroactive attentional cues in working memory involve both distractor inhibition and target enhancement, as indicated by lateralized alpha oscillations.

The paper presents an EEG/fMRI dataset from human subjects performing a perceptual decision making task, available for validating computational models and processing algorithms.

The paper investigates how frontoparietal cortex represents information across different stages of cognitive processing and finds that MD regions show flexibility in representing task demands.

This study decodes EEG signals to reveal how task-set representations dynamically influence stimulus and response processing in humans.

This study uses eye tracking and EEG to decompose Symbol Search performance into cognitive components, finding that efficient performance depends more on memory encoding than general processing speed.

This paper presents a unified model of distraction that explains perceptual, cognitive, and economic decision-making phenomena and predicts new behavioral outcomes.

This study uses fMRI to show that ventromedial prefrontal cortex encodes subjective effort valuation while anterior cingulate encodes choice difficulty during effort-based decisions.

The paper proposes a dual competition model between the basal ganglia and cortex to explain action-outcome and stimulus-response processes in decision making, validated in primates.

This study shows that perceptual decision-making and response inhibition share a common computational mechanism involving interactive stochastic accumulators.

This study investigates how cognitive conflict is resolved during decision-making, finding that executive control mechanisms, not early sensory modulation, dominate in resolving conflict.

This study investigates the role of dopamine in serial decision-making by examining Parkinson's disease patients on and off medication in a patch-foraging task, finding that dopamine affects the opportunity cost of time.

The paper isolates neural activity related to decision-making in a gambling task and demonstrates that the ventral striatum mediates the relationship between expected value and choice.

The paper investigates how alpha EEG power suppresses Pavlovian bias during social reinforcement learning, contrasting it with theta power for monetary feedback.

The paper uses fMRI and computational modeling to show that a Kalman filter best explains action-outcome learning, with the medial prefrontal cortex distinguishing action effects from background noise.

The paper identifies categorical representations of decision variables in orbitofrontal cortex using rats performing a complex task, showing neurons encode distinct decision-related features.

The paper demonstrates covert learning in the basal ganglia by showing monkeys improve performance after GPi inactivation is reversed, indicating value evaluation occurs without conscious awareness.

The paper investigates how amygdala input differentially affects prefrontal cortex encoding of reward-based decisions through local field potentials and single neuron activity in monkeys.

Meta-analysis across human neuroimaging studies in four task domains shows preferential activation of anatomically defined ventral anterior, dorsal anterior, and posterior insula sub-regions across emotion, pain, and cognitive control.

The paper presents a new analysis technique for multi-step decision tasks that reduces confounding issues and provides a theory-neutral view of behavior.
