Vagus nerve stimulation increases stomach-brain coupling via a vagal afferent pathway

This study shows that vagus nerve stimulation increases stomach-brain coupling in specific brain regions and correlates with changes in hunger ratings.

Acute vagus nerve stimulation does not affect liking or wanting ratings of food in healthy participants

Brain signaling dynamics after vagus nerve stimulation

This study investigates the effects of transcutaneous vagus nerve stimulation (tVNS) on brain signaling using fMRI, finding increased NTS activation but no changes in dynamic functional connectivity or gastric motility.

Influenca: a gamified assessment of value-based decision-making for longitudinal studies

Influenca is a gamified app for repeated assessment of reward learning, showing moderate reliability in reinforcement learning parameters over time.

Non-invasive vagus nerve stimulation boosts mood recovery after effort exertion

This study shows that non-invasive vagus nerve stimulation improves positive mood after physical and cognitive exertion, with effects dependent on baseline mood.

Can't decide how much to EAT? Effort variability for reward is associated with cognitive restraint

The paper examines the relationship between variability in reward seeking and eating behaviors, finding that greater effort variability is linked to lower cognitive restraint.

Localized prediction of glutamate from whole-brain functional connectivity of the pregenual anterior cingulate cortex

The paper uses machine learning to predict local glutamate levels from functional connectivity in the pregenual anterior cingulate cortex, showing better prediction for p32 than p24.

Evidence for modulation of EEG microstate sequence by vigilance level

This study shows that EEG microstate parameters are associated with vigilance levels, with different effects on microstate class durations and transitions.

Vagus nerve stimulation increases vigor to work for rewards

This study shows that transcutaneous auricular vagus nerve stimulation (taVNS) increases vigor for rewards, particularly for food, but not effort maintenance, with left-side stimulation having a stronger effect.

Stimulation of the vagus nerve reduces learning in a go/no-go reinforcement learning task

This study shows that vagus nerve stimulation impairs reinforcement learning by reducing the learning rate, particularly after punishment, in a go/no-go task.

Non-invasive stimulation of vagal afferents reduces gastric frequency

This study shows that non-invasive vagus nerve stimulation reduces gastric frequency without affecting resting energy expenditure.

The anterior insula channels prefrontal expectancy signals during affective processing

This study investigates how the anterior insula modulates prefrontal cortex responses to emotional stimuli based on expectancy signals using fMRI and cross-correlation analyses.

Addressing the reliability fallacy: Similar group effects may arise from unreliable individual effects

The paper shows that reliable group brain activation patterns do not guarantee reliable individual measurements and provides a toolbox to assess fMRI contrast reliability.
