The paper examines the relationship between frontal cortical activity and pupil responses in mice during decision-making, finding that pupil-linked arousal tracks decision uncertainty and predicts future behavior adjustments.

This study examines age-related impairments in sensory-motor reconfiguration and pupil-linked arousal during decision-making tasks, finding reduced flexibility in switching stimulus-response mappings in older adults.

This study investigates how temporal structure affects evidence accumulation in human decision-making, finding that subjects dynamically adjust their strategies to compensate for memory loss during breaks.

The paper investigates whether task-irrelevant sounds affect memory formation and finds they boost pupil-linked arousal but not memory success.

The paper shows that human brains rhythmically sample decision alternatives at 11 Hz, with attention shifts occurring at troughs and focus deepening at peaks.

The paper investigates brain dynamics during internal decisions about stimulus-response rules, finding widespread cortical representations of internal beliefs.

This study shows that NMDA receptor blockade reduces history-dependent biases in perceptual decisions, while GABA-A enhancement increases within-trial evidence transience.

This study shows that high-amplitude oscillatory events coordinate large-scale cortical networks during decision-making and attention, revealing a new mechanism for dynamic brain function.

This study investigates how confidence in decisions is shaped by competitive neural signals across multiple cortical areas using magnetoencephalography.

This study shows that catecholamines reduce choice history biases in perceptual decisions by affecting sensory evidence accumulation.

The paper shows that brain activity in the parietal cortex encodes evidence consistently with prior choices, leading to confirmation bias in decision-making.

This study investigates the interactions between serotonergic and noradrenergic systems in awake mice, revealing their combined and distinct roles in pupil-linked arousal.

This study investigates whether task-irrelevant auditory stimuli can manipulate central arousal during decision-making, finding they affect pupil responses but not decision formation.

The paper links individual differences in belief updating and phasic arousal to psychosis proneness in a community sample.

This study identifies large-scale neural dynamics changes in psychosis patients that resemble those from GABA-A and NMDA receptor manipulations and correlate with clinical symptoms.

This study examines working memory dynamics in older adults and MCI patients, finding age-related declines in memory quality and links to cognitive integrity.

This study investigates the role of GABAergic inhibition in the 40 Hz auditory steady-state response (ASSR) using MEG and pharmacological interventions, finding that GABAA receptor agonists increase ASSR amplitude while NMDA blockers have no effect.

The paper shows brainstem arousal systems and pupil size correlate with cortical interactions during flexible decision-making.

This study uses fMRI and pupillometry to show that both types of deviant stimuli activate multiple subcortical systems, including the locus coeruleus, in a 'local-global' paradigm.

The paper shows that history-dependent biases adapt to environmental correlations and selectively influence motor cortical activity during decision formation.

This paper introduces a new information-theoretic measure, FIT, to quantify feature-specific information transfer between brain regions using simulated and empirical neural data.

This study shows that brain-wide correlated variability between sensory and motor regions reflects participants' beliefs about active task rules during sensory-motor mapping tasks.

The paper identifies parietal cortex signals that mediate perceptual choice repetition bias through sustained gamma-band activity.

The paper uses an auditory accessory stimulus to show that increased pupil-linked phasic arousal reduces choice bias without affecting response caution.

The paper examines how arousal influences cortical processing by analyzing pupil and neuronal population dynamics across the human brain.

The paper identifies circuit mechanisms by which catecholamines and acetylcholine modulate cortex-wide network interactions and exploration behavior in humans.

The paper examines how the brain adapts evidence accumulation during changing environments using human behavior and MEG data, revealing links between decision dynamics and cortical circuit activity.

This study shows that making choices during a prolonged evidence stream alters how evidence is weighted over time, leading to confirmation bias.

This paper combines evidence accumulation models with confidence reporting to show that confidence dynamics depend on time and evidence strength.

The paper maps the dynamics of perceptual decision signals across the human cortex using magnetoencephalography and identifies a low-frequency endogenous component in primary visual cortex.
