Scientists probe Brain's wiring to supercharge depression therapy
NCT ID NCT07593222
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study aims to understand how a quick, non-invasive brain stimulation treatment called iTBS works in people with depression. Researchers will measure brain activity before and after stimulation in 100 participants (healthy volunteers and those with depression) using EEG and MRI. The goal is to uncover the brain mechanism behind iTBS, which could lead to more effective treatments for those who don't respond to standard therapies.
