Nerve stimulation and upper gut movement in healthy adults

This study tests whether stimulating the vagus nerve (a major nerve in your body) with a small electrical device affects how your stomach moves and processes food. Researchers want to understand this effect in healthy people to potentially help those with digestive problems in the future.

This study tests a new way to listen to the vagus nerve in awake people. It may help understand how the nerve controls body functions like heart rate and digestion.

This study tests whether a small device that gently stimulates a nerve in your ear can help reduce nausea. Researchers will enroll healthy adults to see if this non-drug approach is safe and effective.

This study tests a non-invasive device that gently stimulates a nerve in your ear to see how it affects your body's nervous system. Researchers will compare different treatment durations in healthy volunteers to understand the best approach.

This study tests a non-invasive nerve stimulation technique applied to the ear at different frequencies in healthy people. Researchers want to understand how this stimulation affects your body's automatic nervous system (the systems that control heart rate, breathing, and digestion without you thinking about them).

This study looks at how vagus nerve stimulation (VNS) affects how your stomach works, like emptying and stretching. It may help researchers understand the digestive side effects of VNS in people who already have a VNS device for epilepsy or depression.
