What this study is about

Researchers are testing a new treatment to see how it affects the brain, stomach, and autonomic nervous system. The trial will use noninvasive nerve stimulation called transcutaneous electro-accupoint stimulation (TEAS) on healthy adults. Participants will have their brain activity monitored using fMRI scans.

Simplified from trial records by PatientMatch.
