NCT ID NCT04680481

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether a gentle electrical current applied to the scalp can improve working memory in 9 adults with epilepsy who already had brain electrodes implanted. The stimulation targeted frontal and parietal brain areas at different frequencies. Researchers measured changes in brain activity and memory performance during the stimulation.
