Brain Stimulation for Meditation
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether brain stimulation can help individuals quickly enter a meditative state without years of practice. Researchers aim to determine if this can enhance openness and overall well-being, similar to regular meditation. Participants will wear a special cap to record brain activity, undergo brain stimulation (specifically, transcranial electrical stimulation or TES, and transcranial electrical stimulation with temporal interference or TES-TI), and complete various tasks. It suits healthy adults who already practice meditation regularly. As an unphased trial, this study offers participants a unique opportunity to contribute to innovative research on enhancing meditation experiences.
Will I have to stop taking my current medications?
You may need to stop taking certain medications that can affect seizure thresholds, like ADHD stimulants, some antidepressants, antipsychotics, bronchodilators, certain antibiotics, and antivirals. It's best to discuss your current medications with the trial team to see if any changes are needed.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Earlier studies found transcranial electrical stimulation (TES) to be safe and easy to handle. Participants reported it as painless and having a good safety record. Another study with children and teens (ages 5-17) also confirmed its safety, noting only a few minor side effects.
For transcranial electrical stimulation with temporal interference (TES-TI), research shows it is safe and easy to tolerate. Studies indicate it does not harm brain function or cause major side effects. This non-invasive method targets specific brain areas.
Current research generally supports the safety of both treatments. These findings can reassure those considering participation about their safety.12345Why are researchers excited about this trial?
Researchers are excited about transcranial electrical stimulation (TES) and its advanced form, TES with temporal interference (TES-TI), because these techniques offer a fresh approach to enhancing meditation. Unlike common methods like mindfulness training or guided meditation, TES and TES-TI use electrical currents to stimulate brain activity directly, potentially boosting cognitive function and focus during meditation. TES-TI, in particular, is intriguing because it uses temporal interference to target deeper brain regions more precisely without affecting surrounding areas. This precision and non-invasiveness could set a new standard for enhancing meditation benefits efficiently and safely.
What evidence suggests that this trial's treatments could be effective for achieving a meditative state?
This trial will compare different brain stimulation techniques, including transcranial electrical stimulation (TES) and transcranial electrical stimulation with temporal interference (TES-TI). Studies have shown that TES can boost various mental skills, such as memory and attention, and is particularly beneficial for individuals with lower mental performance, enabling quicker improvement. Findings suggest that TES-TI enhances working memory by more precisely targeting specific brain areas. It has demonstrated safety and can improve mental functions by enhancing certain brain waves. Both techniques show promise for supporting mental processes similar to those developed through meditation. Participants in this trial may receive either TES, TES-TI, or sham stimulation.46789
