Ultrasound scan to study the body’s automatic (stress) responses
Part of Brain & nervous system clinical trials.
This trial tests a low-intensity ultrasound approach while measuring how your nervous system and body respond automatically (like changes in heart rate or stress signals). It may help researchers learn how to stimulate or monitor these responses safely, using imaging and standard monitoring.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You should not have any of the listed safety “exclusion” issues (for example MRI/CT safety problems).
- You should be able to tolerate the scanning environment (no severe claustrophobia).
- You likely can’t have certain metal or implanted devices that are unsafe for MRI (like pacemakers or neurostimulators).
- You should not be pregnant, since CT is involved.
- You should not have certain conditions or medications that affect the brain or heart signals (such as neurologic disorders, heart disease, or many heart medicines).

This study tests how low-power focused ultrasound changes brain signals measured during MRI. You may help researchers understand how ultrasound can affect brain activity, even if you don’t have a known brain condition.
This study uses low-intensity focused ultrasound to see how it affects memory. It may help researchers understand how to improve memory or treat conditions that affect it.
This study looks at how long a low-intensity focused ultrasound treatment effect lasts. It may help researchers plan safer, more effective use of this technology in future studies.
This study tests whether low-intensity focused ultrasound changes brain activity signals measured on an MRI scan. It is done in healthy people to better understand how ultrasound may affect the brain without surgery.
This study uses a special kind of ultrasound and MRI scans to check safety and see how the brain responds. It may help researchers understand the possible mechanism of this treatment, but it is designed for people who are healthy and can complete the full visit schedule.
This study tests the safety of a brain stimulation approach that uses special brain recording and “focused ultrasound” targeted by brain signals. It is designed for healthy adults and checks whether the procedure is tolerated without serious side effects.
