The paper shows that pupil dilation and slow wave ERP reflect surprise during decision-making under uncertainty, and that these signals are independent and depend on feedback awareness.

This study shows that phasic arousal suppresses decision biases in both mice and humans across different decision-making domains and sensory systems.

This study compares 7 T and 3 T fMRI responses in human brain regions during a decision-making task, finding greater 7 T benefits in subcortical areas like the brainstem.

The paper shows that decision confidence influences the speed-accuracy tradeoff in subsequent decisions by adjusting decision bounds based on previous confidence reports.

The paper shows that choice history biases perceptual decisions by altering evidence accumulation rather than shifting the starting point of accumulation.

The paper investigates the relationship between neural variability and oscillations, finding that variability quenching is linked to changes in alpha-beta band power.

The paper shows that pupil responses reflect internal belief states during perceptual decisions, scaling with decision confidence and prediction errors.

This study identifies two distinct brain-wide activity patterns modulated by catecholamines using fMRI and pharmacological intervention.

The paper develops a computational MEG approach to map cortical transients driven by surprise about sensory event timing, showing beta-band suppression in frontal regions.

This study shows that pupil dilation during encoding predicts long-term memory retention of visual and auditory stimuli, highlighting the role of arousal in memory formation.

This study shows that catecholamines change the intrinsic variability of cortical activity and perception, increasing the net E/I ratio in visual and parietal cortex, while acetylcholine does not.

The paper shows that choice history biases in perceptual decisions arise from confidence-weighted accumulation of past choices, adapting to environmental context.
