Vasopressin and Pain Perception in the Brain

Intranasal vasopressin will be administered shortly before the fMRI experiment.

Intranasal saline will serve as a placebo for participants in the Saline Arm

During the observational learning intervention, participants will learn the experience of analgesia in another person via a video. Participants will learn the analgesia nature of the placebo cream and the neutral nature of the control cream.

All participants from the intranasal vasopressin and intranasal saline groups will go through a fMRI data acquisition to obtain the brain structural, brain resting-states and functional MRI scans.
