Temporal Interference Stimulation for Healthy Adults

(CAP-TI Trial)

This trial aims to explore whether a type of non-invasive brain stimulation, known as temporal interference stimulation, can affect brain activity during sleep. Researchers focus on sleep spindles, specific brain rhythms that occur during sleep. The study involves up to 24 healthy participants attending three overnight sessions. Individuals who are healthy, reside in Dane County, Wisconsin, and have no history of neurological disorders or sleep issues might be suitable candidates. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research on sleep and brain activity.

Yes, you may need to stop taking certain medications that can affect seizure thresholds, such as ADHD stimulants, some antidepressants, antipsychotics, bronchodilators, certain antibiotics, antivirals, and some over-the-counter antihistamines.

Research has shown that temporal interference stimulation (TI-TES) is generally safe and well-tolerated. Studies identified mild sensations, such as tingling or itching on the skin, as the most common side effects. Many participants reported these sensations, but they were not serious. Other research found no significant problems with brain or mental functions due to TI-TES. Most participants found the treatment comfortable and did not experience major issues. Overall, TI-TES appears to be a safe option for those considering participation in a clinical trial.¹²³⁴⁵

Researchers are excited about Temporal Interference Stimulation because it offers a novel way to target specific areas of the brain non-invasively. Unlike traditional brain stimulation techniques that directly activate neurons, this method uses intersecting electrical fields to focus the stimulation deep within the brain, potentially reaching regions like the thalamus without affecting the surrounding tissues. This fine-tuned targeting could enhance our understanding of brain functions and lead to more effective treatments for neurological conditions in the future.

Research has shown that temporal interference stimulation (TI-TES) can meaningfully change brain activity. One study found that TI-TES improved working memory by boosting activity in specific brain areas. Other research indicated that TI-TES could increase activity in deeper brain regions, suggesting potential benefits for various brain functions. Some studies have also demonstrated short-term benefits for conditions like Parkinson's and epilepsy, though more evidence is needed. Overall, TI-TES appears promising for temporarily altering brain activity and enhancing certain cognitive functions.⁵⁶⁷⁸⁹
