Brain Stimulation for Negative Emotions
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial investigates whether a non-invasive technique called transcranial temporal interference stimulation (tTIS) can reduce negative emotions. It also examines how care providers' expectations might influence the treatment's effectiveness. Participants will receive either active or inactive tTIS and hear either positive or negative messaging about the treatment's potential benefits. This study suits individuals without psychiatric diagnoses, seizure disorders, or severe migraines who are comfortable with the trial's tasks and procedures. As an unphased trial, it offers participants the chance to contribute to groundbreaking research in emotional regulation techniques.
Will I have to stop taking my current medications?
Yes, you will need to stop taking any medications that affect the central nervous system or are used for neurological or psychiatric treatment to participate in this trial.
What prior data suggests that transcranial temporal interference stimulation (tTIS) is safe for reducing negative emotions?
Research has shown that transcranial temporal interference stimulation (tTIS) is generally safe and well-tolerated in people. One study found that tTIS can be used at certain electricity levels without causing harm, allowing it to safely reach deep brain areas through electrical currents applied to the scalp.
Another study confirmed that tTIS is safe for humans and can target specific brain areas, such as the hippocampus, without causing major side effects. Participants reported few, if any, negative reactions during these trials.
While researchers continue to study tTIS, current evidence suggests it is a low-risk option for brain stimulation.12345Why are researchers excited about this trial?
Researchers are excited about Transcranial Temporal Interference Stimulation (tTIS) because it offers a fresh approach to addressing negative emotions by using non-invasive brain stimulation. Unlike traditional treatments like medication or psychotherapy, tTIS uses precise electrical signals to target specific brain regions without the need for surgery or systemic drug exposure. This method is believed to minimize side effects and enhance treatment precision, potentially offering quicker and more effective relief from negative emotional states.
What evidence suggests that transcranial temporal interference stimulation (tTIS) might be an effective treatment for reducing negative emotions?
Research has shown that transcranial temporal interference stimulation (tTIS), which participants in this trial will receive, can reach deep brain areas without surgery. One study found that tTIS might help reduce depression symptoms in people with bipolar disorder. Another study suggested that tTIS could improve mental health by lowering negative emotions. These results are encouraging, but more research is needed to understand how effectively tTIS reduces negative feelings across different groups.16789
Are You a Good Fit for This Trial?
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
