NCT ID NCT06980090
First seen Jan 06, 2026 · Last updated Jun 19, 2026 · Updated 26 times
Summary
This study tests whether a gentle, non-invasive brain stimulation technique called tTIS can reduce negative emotions like fear and pain. It also looks at how a caregiver's positive or negative words might boost or weaken that effect. About 196 healthy adults will take part, including medical students and doctors. The goal is to understand the brain mechanisms behind expectations and emotions, not to develop an immediate treatment.
