Global nonequilibrium cortical dynamics tie mid-level pupil-linked arousal to optimal task performance in humans

The paper examines how global cortical dynamics, measured via EEG and pupil-linked arousal, relate to perceptual sensitivity under different neuromodulator conditions.

Baseline activity of V1 interneurons connects pupil-linked arousal to engaged behavioral state

The paper shows that baseline activity of V1 interneurons mediates the relationship between pupil-linked arousal and engaged behavioral state in mice and humans.

Adaptive arousal regulation: Pharmacologically shifting the peak of the Yerkes-Dodson curve by catecholaminergic enhancement of arousal

This study pharmacologically manipulates arousal in humans to test its impact on performance, finding that catecholaminergic enhancement shifts the arousal-performance curve while cholinergic agents do not.

A disinhibitory circuit mechanism explains a general principle of peak performance during mid-level arousal

The paper provides evidence for the inverted U-shaped relationship between arousal and performance in perceptual decision-making and presents a neurobiological model explaining it.

Catecholaminergic neuromodulation and selective attention jointly shape perceptual decision-making

This study investigates how catecholaminergic neuromodulation and spatial attention jointly influence perceptual decision-making through behavioral, algorithmic, and neural measures.

Preserved sensory processing but hampered conflict detection when stimulus input is task-irrelevant

The paper shows conflict detection in sensory input requires attention to at least one conflicting feature, while basic sensory processing occurs without attention.

Decreased alertness reconfigures cognitive control networks

The paper investigates how natural fluctuations in alertness affect cognitive control by analyzing neural and behavioral responses during a conflict task under varying alertness conditions.

The brain detects stimulus features, but not stimulus conflict in task-irrelevant sensory input

The paper shows that the brain detects stimulus features but not conflict in task-irrelevant sensory input using EEG data from humans.
