This study aims to understand how different parts of your brain involved in the sense of smell affect your behavior. Researchers will use a technique called transcranial ultrasound stimulation (TUS) to gently stimulate specific brain areas: the piriform cortex (TUS PirC), the amygdala (TUS Amy), or a control area (TUS Sham). The main goal is to see if stimulating these areas changes how you perform tasks related to smell. You may be eligible if you are a healthy, right-handed adult between 18 and 45 years old. The study is currently unclear on its recruitment status, but plans to enroll 80 participants.

Study design

This interventional study plans to enroll 80 healthy participants. It is designed to see how stimulating specific brain areas with ultrasound affects smell-related tasks.

What's involved

You can volunteer for up to two experiments, each requiring five visits about one week apart. Before visits, you may have limits on food, alcohol, and caffeine, and your health and sense of smell will be checked.

Compensation

Not stated in the trial record.

Follow-up

Your task performance will be measured immediately after each transcranial ultrasound stimulation (TUS) session.
