This study investigates how non-invasive vagus nerve stimulation affects pupil dilation and finds that effects depend on differences in perceived sensation between stimulation and sham conditions.

This paper performs a Bayesian meta-analysis comparing continuous and pulsed tVNS protocols on pupil dilation, finding stronger evidence for pulsed tVNS effects.

This paper reviews the role of ghrelin and GLP-1 in human reward systems using fMRI, finding ghrelin increases reward responses while GLP-1 effects are less consistent.
