NCT ID NCT07658274
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a mild electrical current applied to the forehead during sleep can improve memory in healthy young adults. Thirty participants will spend four nights in a sleep lab, receiving either real or fake stimulation while their brain waves, heart rate, and breathing are monitored. The goal is to see if this technique can strengthen procedural and working memory overnight.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcutaneous electrical nerve stimulation (eTNS)
- What this could lead to
- If it works, this could point toward a non-invasive way to enhance memory consolidation during sleep.
- What could go wrong
- This is a very small, early-stage study in healthy volunteers, not patients. The effects may be small or not translate to real-world memory improvement.
