U.S., June 19 -- ClinicalTrials.gov registry received information related to the study (NCT07657260) titled 'Investigating the Transcutaneous vs. Transcranial Mechanisms of Trigeminal Nerve Stimulation (eTNS) Using fMRI' on June 15.

Brief Summary: Transcutaneous Trigeminal Nerve Stimulation (eTNS) is a non-invasive technique that modulates brain activity by applying electrical currents to the forehead. However, it remains unclear whether its effects are primarily driven by activating peripheral nerves in the skin (the transcutaneous pathway) or by the electrical current passing directly through the skull into the brain (the transcranial pathway).

This study aims to differentiate these two mechanisms in healthy volunteers. Participants wil...
