The paper identifies common neural patterns associated with task engagement and disengagement in macaques using fMRI, showing causal links to specific brain regions.

This study shows that medial prefrontal cortex (mPFC) reduces reward-seeking behavior under positive punishment risk by decreasing reward sensitivity, but not negative punishment.

This study compares motor inhibition in reactive and anticipated movement tasks, finding no difference in inhibition speed but faster action reprogramming in anticipated movements and age-related slowing in both.

The paper shows individual differences in decision-making strategies are linked to neural efficiency in memory or reinforcement systems.

This study investigates how pupil dilation reflects effortful action invigoration in overcoming aversive Pavlovian biases during a task involving subliminal emotional cues.

This study investigates how cognitive effort affects neural representations during working memory using fMRI, finding that frontal cortex activity predicts visual cortex decoding accuracy during effortful trials.

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

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 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.

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 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 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 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.

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 identifies an extended motivational signal in the orbitofrontal cortex to anterior cingulate cortex pathway during learning in mice.

The paper shows that anterior cingulate cortex inhibition disrupts information-based choice preference in female rats, suggesting a sex-dependent role for ACC in decision-making involving information.

This study investigates subcortical involvement in working memory updating using 7T MRI and finds subcortical activation during gate closing and substitution, suggesting a role in general updating processes rather than specific gating.

This study uses fMRI and Hidden-Markov models to show that mixed valence feelings have distinct and less consistent neural patterns compared to univalent states in specific brain regions.

The paper uses fMRI and a novel multivariate analysis to show orthogonal neural representations of target and distractor processing in cognitive control tasks.

This study investigates the 5-CSRTT task in rats, finding that response accuracy reflects sustained attention while omissions indicate failure to attend to stimulus location.

This study examines how low alcohol doses affect inhibitory control and brain activity during a stop-signal task in healthy social drinkers.

The paper investigates how reinforcement and its omission affect trial-by-trial changes in response bias during perceptual decision-making in rats, finding that a generalized matching law-based model better explains the data than traditional criterion learning models.

This study investigates the roles of caudate and putamen in spatial self-ordered sequencing in marmosets using glutamate receptor blockade, showing distinct contributions to variable and fixed sequencing tasks.

The paper tests whether threat cues improve perceptual discrimination and finds no improvement despite increased neural activity in the frontoparietal network.
