Oxytocin's nerve effects under the microscope in healthy volunteers

This study looks at whether oxytocin, a natural hormone, can change how nerves react to light touch and painful pressure after a small area of skin is heated. Sixty healthy adults will receive either oxytocin or a placebo through an IV, and a tiny needle will record nerve signals before and after the heat. The goal is to understand how oxytocin affects pain signaling, not to treat any condition.
