This study uses a passive auditory oddball protocol to measure pupil-linked signatures of Bayesian belief updating during environmental change.

The paper investigates how two neural signals encode different aspects of belief formation during decision-making in a volatile task, finding that one signal tracks evolving beliefs while the other encodes belief updates.

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

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

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

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 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 investigates how temporal expectations affect perceptual decision-making by manipulating cue timing and analyzing behavioral and neural data.

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.

The paper shows that neural markers of confidence, specifically post-decisional ERP components, predict information-seeking behavior in humans.
