Brain Stimulation for Negative Emotions
Trial Summary
What is the purpose of this trial?
The goal of this clinical trial is to learn whether non-invasive brain stimulation, called transcranial temporal interference stimulation (tTIS), can reduce negative affect, and how expectations shaped by care providers influence these effects.The main questions this study aims to answer are: (1)Does active tTIS reduce negative affect more effectively than sham (inactive) tTIS? (2)Do positive treatment expectations enhance the effects compared to negative expectations?Participants will: (1) Receive either active or sham tTIS. (2) Be provided with positive or negative messaging regarding treatment effectiveness. (3) Interact with care providers and complete assessments measuring negative affect and physiological responses.
Eligibility Criteria
This trial is for individuals interested in exploring how brain stimulation and care provider expectations affect emotions. Participants will undergo non-invasive brain stimulation and receive messages about treatment effectiveness to measure changes in their emotional state.Inclusion Criteria
