Cortex-wide Dynamics of Internal Decisions About Behavioral Context

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

Dynamics of brainstem arousal systems and pupil size predict cortical interactions for flexible decision-making

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

Flexible Sensory-Motor Mapping Rules Manifest in Correlated Variability of Stimulus and Action Codes Across the Brain

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.

Circuit mechanisms for chemical modulation of cortex-wide network interactions and exploration behavior

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

Neuronal timescales are functionally dynamic and shaped by cortical microarchitecture

The paper infers neuronal timescales from human intracranial recordings and shows they align with cortical microarchitecture and cognitive functions.

Temporal expectation hastens decision onset but does not affect evidence quality

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

Sustaining attention for a prolonged period of time increases temporal variability in cortical responses

This study examines how prolonged attention affects neural responses, finding that task performance and temporal variability decline over time, while motivation does not fully restore performance.

Amplification and Suppression of Distinct Brain-wide Activity Patterns by Catecholamines

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

Catecholaminergic Manipulation Alters Dynamic Network Topology Across Behavioral States

This study shows that manipulating catecholamine levels with atomoxetine changes the functional connectome's dynamic network topology in response to cognitive demands.
