What this trial studies

This project aims to evaluate the feasibility of using traveling wave transcranial alternating current stimulation (tACS) to enhance working memory performance and modify large-scale brain connectivity in patients with surgically implanted electrodes for epilepsy evaluation. The study will involve administering tACS to assess its effects on cognitive function in this specific patient population. By focusing on surgical epilepsy patients, the research seeks to explore innovative non-invasive methods to potentially improve cognitive outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have or are scheduled for surgically implanted electrodes for epilepsy evaluation.

Not a fit: Patients who have diminished capacity to consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved working memory and cognitive function in patients with epilepsy.

How similar studies have performed: While the specific approach of using traveling wave tACS is novel, similar non-invasive brain stimulation techniques have shown promise in enhancing cognitive functions in other studies.
