Summary

This study uses a safe, non-invasive technique called transcranial direct current stimulation (tDCS) to apply a very weak electrical current to the scalp of healthy adults. Researchers will compare how younger (20-40) and older (60-80) participants perform computer tasks and how their brain activity changes on MRI scans. The goal is to understand how age influences the brain's response to stimulation, which could guide future research into cognitive support.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: transcranial direct current stimulation (tDCS) - a mild electrical current applied to the scalp
What this could lead to: If successful, this study could help researchers understand how brain stimulation might be used in the future to support cognitive function in aging.
What could go wrong: This is a basic science study in healthy volunteers, not a treatment trial. The results may not lead to any direct medical application, and effects may vary between individuals.
