Arousal does not enhance the dominant spatial scope of attention Open
A fundamental aspect of attention is its spatial scope: whether attention is narrowly focused or more broadly distributed across the visual field. Here, we examined whether the spatial scope of attention is modulated by tonic arousal level…

A normative account of the trade-off between cognitive stability and flexibility Open
Optimal decision making often requires a compromise between opposing functional demands. This is illustrated by the extensive literature that focuses on the optimal trade-off between response speed versus accuracy. However, a formally rigo…

Pupil-linked arousal counteracts the positive effects of reward anticipation on incidental memory encoding Open
The anticipation of a potential reward has been shown to enhance episodic memory, but the underlying mechanisms remain unclear. While previous research has highlighted the role of attention in improving memory for reward-associated stimuli…

Neuromodulatory influences on propagation of traveling waves along the unimodal–transmodal gradient Open
Understanding the factors underlying brain activity fluctuation is important to understand the flexible nature of the brain and cognition. Growing evidence indicates that functional magnetic resonance imaging (fMRI) activity travels as wav…

Subcortical nuclei of the human ascending arousal system encode anticipated reward but do not predict subsequent memory Open
Subcortical nuclei of the ascending arousal system (AAS) play an important role in regulating brain and cognition. However, functional MRI (fMRI) of these nuclei in humans involves unique challenges due to their size and location deep with…

Strength of Low-Frequency EEG Phase Entrainment to External Stimuli Is Associated with Fluctuations in the Brain's Internal State Open
The brain attends to environmental rhythms by aligning the phase of internal oscillations. However, the factors underlying fluctuations in the strength of this phase entrainment remain largely unknown. In the present study, we examined whe…

Subcortical nuclei of the human ascending arousal system encode anticipated reward but do not predict subsequent memory Open
Subcortical nuclei of the ascending arousal system play an important role in regulating brain and cognition. However, functional MRI of these nuclei in humans involves unique challenges due to their size and location deep within the brain.…

Neuromodulatory influences on propagation of brain waves along the unimodal-transmodal gradient Open
Brain activity fluctuates over time, and understanding the factors that influence such fluctuations is important to understand the flexible nature of the brain and cognition. Growing evidence suggests that fMRI brain activity shows spatio-…

Boosting arousal and cognitive performance through alternating posture: Insights from a multi‐method laboratory study Open
This study investigated the role of arousal and effort costs in the cognitive benefits of alternating between sitting and standing postures using a sit‐stand desk, while measuring executive functions, self‐reports, physiology, and neural a…

Phasic alertness generates urgency and amplifies competition between evidence accumulators Open
Although phasic alertness generally benefits cognitive performance, it often increases the interference caused by distracting information, resulting in impaired decision-making and cognitive control. However, it is unclear why phasic alert…

The effect of reward-induced arousal on the success and precision of episodic memory retrieval Open
Moment-to-moment fluctuations in arousal can have large effects on learning and memory. For example, when neutral items are predictive of a later reward, they are often remembered better than neutral items without a reward association. Thi…

Non‐invasive vagus nerve stimulation and the motivation to work for rewards: A replication of Neuser et al. (2020, <i>Nature Communications</i>) Open
The vagus nerve is thought to be involved in the allostatic regulation of motivation and energy metabolism via gut‐brain interactions. A recent study by Neuser and colleagues (2020) provided novel evidence for this process in humans, by re…

Broadening of attention dilates the pupil Open
Inconclusive evidence suggests that the pupil is more dilated when the breadth of attention is broad compared to narrow. To further investigate this relationship, we recorded pupil size from healthy volunteers while inducing trial-wise cha…

Pupil size reflects activation of subcortical ascending arousal system nuclei during rest Open
Neuromodulatory nuclei that are part of the ascending arousal system (AAS) play a crucial role in regulating cortical state and optimizing task performance. Pupil diameter, under constant luminance conditions, is increasingly used as an in…
