NCT04276805

Brief Summary

We need better tools to both enhance brain health and improve cognitive performance in healthy brain aging so that it can be delayed, reduced, or even reversed. The present proposal is designed to evaluate the pairing of cognitive training with a non-invasive neurostimulation technology that has shown promise in both increasing neuroplasticity and in enhancing cognitive performance, transcutaneous vagal nerve stimulation (tVNS).
