Summary

This study looks at how focused ultrasound (sound waves) aimed at the cerebellum changes brain activity and thinking in 20 healthy adults aged 18 to 40. Participants do thinking tasks after real or fake ultrasound. The goal is to learn how the cerebellum affects brain function, not to treat any disease.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
