This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a non-invasive brain stimulation technique called transcranial alternating current stimulation (tACS) to see if it can help people with PTSD process threats more safely. Researchers believe that PTSD involves changes in three connected brain regions that control fear and sensory processing, and they want to test whether stimulating the brain can restore normal communication between these areas. You would receive either active brain stimulation, a fake version, or a different type of stimulation while your brain activity is measured.
People with PTSD often struggle with overwhelming fear responses and heightened sensitivity to threats, even in safe situations. This trial exists to test a new understanding of how PTSD changes the brain's wiring and whether gentle electrical stimulation can help normalize these patterns without medication or surgery.

You would visit the research center for experiments involving brain imaging and simple sensory tasks. During your visit, electrodes would be placed on your scalp to deliver mild electrical stimulation while researchers measure your brain activity using a special scanner and EEG. You would complete visual search tasks and smell-detection tasks involving both neutral and threatening images or odors, both before and after the stimulation. The entire study involves two experiments designed to test how the brain stimulation affects your sensory processing and threat responses.
